The Graveyard - Products No Longer Supported => Routers / COVR => DGL-4500 => Topic started by: Corpus on October 16, 2010, 09:37:53 PM
-
My DGL-4500 was working well for about a year until seemingly a couple months ago. Not sure if it was a firmware update or what. But...
At any random time the router will simply loose connection then reconnect all within 30 seconds or so.
Some times I get maybe a day of up time with it and other days it will loose connection 6 or more times.
My set up.
2 wired computers - My computer is used mainly for gaming and my other computer is used by my wife for surfing.
iPod, iPhone and printer use Wi-Fi
I am running a MOTOROLA SB5100 SURFboard cable modem through Shaw cable
Router firmware 1.23.NA
I read that this router can "crash under load" So if I am running a game and my wife is surfing could this be causing the connection loss? It does mainly happen when I am gaming. (Always when I am kicking butt too) Grrrrr. Anyway, or maybe it is happening more then I realize and only notice it when I am gaming. My main game right now it BFBC2. I don't have any port forwarding on nor am I using gamefuel... Well it is enabled but I have never configured it to anything.
Furynutz.. Sorry about my negativity just frustrated is all and thanks for the offer to help me out.

What do the router logs say? And the firmware doesn't update on its own, so unless you upgraded it, its not a variable. What is your network though?
1. What ISP?
2. When you loose it on one, do you loose it on all your computers?
3. Is your network just Modem > DGL-4500?
4. What do the logs say around the time of the problem? (192.168.0.1 Status>logs)
5. If you have cable, what do the logs of your modem say? (192.168.100.1 Logs tab)
-
1. What ISP? - Shaw Cable
2. When you loose it on one, do you loose it on all your computers? Everything goes down for for a 20 or 30 seconds.
3. Is your network just Modem > DGL-4500? - Motorola SB5100 modem connected to the DGL-4500
4. What do the logs say around the time of the problem? (192.168.0.1 Status>logs)
22:10:38 2010 WAN interface speed measurement completed. Upstream speed is 1039 kbps

5. If you have cable, what do the logs of your modem say? (192.168.100.1 Logs tab) How do I check the logs of my modem? Didn't even know you could do that.
Thanks for having a look at this for me.

I'm having a similar issue to you, and after some pokin' around I found out how to access the logs of the cable modem. In your browser, go to 192.168.100.1 (http://192.168.100.1). There should be a Login somewhere, and the default user/pass should be listed beneath it.

Corpus, I would check out the cable modem log and see if there could be and issue with the cable modem and see what UP time it's reporting. If the cable modem is reporting the same up time or close to what the 4500 is seeing then the 4500 is actually not crashing as it's loosing connection with the cable modem as that it going down as well. I would see if the cable modem is having any issues. I would also check the cable wire coming into the house. Are there any cable tv splitters in line? Its not recommended to use splitters in line, if they are needed, use HIGH quality ones, less the better or use an amp to keep the signal up to par going into the cable modem. I don't use cable tv here so my line is solid all the way through. From the cable modem, I would check the LAN cables and make sure they are good. I use a 1ft cable between the cable modem and 4500. As for this router crashing under load. I can testify that me and others have been using this router under load, weather DL'g, multiple xboxes or what ever it might be and these routers are solid.
A lot of issue seen have to do with user set up and how this router is configured. Yes this router does work well out of the box. Be aware that enabling gamefuel out of the box does not do anything and I would direct you to set up a DHCP IP reservation and then follow my gamefuel sticky instructions to fully enable and use the features this router comes with. These options are tried and true and work well for most most people.
We are here to help you and do understand the frustrations that come with the need of something to work when it doesn't.

Hey guys, thanks for the replies. Now when I input 192.168.100.1 into my browser all I get is a Configuration Manager with only a help link which doesn't do anything.
This is what is displayed
-----------------------------------------------------------------------------------------------------
This page provides information about the startup process of the Cable Modem. If there is a problem with the startup, the word "Failed" may appear in the Status column. Should this occur, visit the Help area and perform the Checkup procedures listed there. If the problem continues, click on the word "Failed" for more detailed information about the failure, or call your service provider for assistance.
The Configuration Manager is divided into several pages, each with a unique purpose. To access any one of these pages, click on the appropriate link at the top or bottom of each page. To update the information while viewing these pages, press the Refresh button on your browser.
Name Purpose
Help The Help Page provides information about how to troubleshoot the Cable Modem.
Standard Checkup
* Check to make sure that the coaxial cable connecting your Cable Modem to the cable wall outlet is connected, and that the screws have been tightened.
* Check to make sure that the power cord on the Cable Modem is plugged into a wall outlet, and that the Power light on the front of the Cable Modem is on.
* If connection is Ethernet, check to make sure that the 10/100BaseT Ethernet cable between the Cable Modem and your computer is connected, and that the connectors have been pushed in until they clicked. For a 10BaseT connection, verify that the top Ethernet Link LED is on. For a 100BaseT connection, verify that both the top and bottom Ethernet Link LEDs are on. For both the 10BaseT and 100BaseT connection, the top LED should blink when there is Ethernet activity.
* If connection is USB, check to make sure that the USB cable between the Cable Modem and your computer is connected, and that the connectors have been pushed in until they are fully seated.
* Check to make sure that the Send, Receive, and Online lights on the front of the Cable Modem are on or blinking. If the lights are off and do not blink, reboot the modem by disconnecting and reconnecting the power plug in the back of the modem.
* Please consult the Cable Modem User Guide for additional information.
-----------------------------------------------------------------------------------------------------
Now as far as for my modem losing connection all my Power,receive,send,online,PC/activity lights never lose connection.
I would really like to look at the "router logs" but can't seem to figure this out. I am pretty sure that my cables are all connected but will pay attention to on a windy day to see if this happens more as it is nice out right now.
There are no splitters that I know of and if I did would remove them knowing that causes signal loss.
We don't have TV only our computer systems. Cable from wall to modem, Ethernet cable from modem to router. That's it. Then one Ethernet cable to my wife system and 2 to my system.
All my LAN cables also seem to be in contact
Mogorain, did you fix your issue?
Again thanks for the help.

You might have an older model or the model doesn't support any options for logs or looking at things. Just view and thats about all you get. As for you cable and splitters, are there any possible splitters comming from the main cable box that maybe on the out side of your house into the room where you have the cable going into the modem? There could be other places for this. Do you have cable tv for the living room or bedroom?
What do the logs on the 4500 say before it looses connection? Are you doing anything at the time of the disconnect? If so, what are you doing? Trying to narrow down what might be causing. I would also ask your ISP if they can look at there logs to see if they see any disconnects on the modem. They will have this information and they can help you troubleshoot on there said of the modem.
You said you have one cable going to your wifes PC and then 2 to your PC? or just one cable going to your PC?
-
Hey Furry, I am awaiting a call back from Shaw Cable as I want to ask them if there has been any disconnects on their side (which I don't think there have been) I also wanted to ask them if they have a newer (better) modem then the one I am currently using.
"As for you cable and splitters, are there any possible splitters comming from the main cable box that maybe on the out side of your house into the room where you have the cable going into the modem? There could be other places for this. Do you have cable tv for the living room or bedroom?"
I thought of this and will have a look. Keep in mind that this issue has only been happening for a couple months prior to that the connection has been fine for almost 2 years.
Here is something that might very well be cause this connection loss.
I failed to mention this as I had to review my setup to see this.
Cabling configuration
#1 - Out of the wall cable into modem.
#2 - Ethernet cable out of modem into my surge protector.
#3 - Ethernet cable out of my surge protector into my DGL-4500 router
#4 - 3 Ethernet cables out to my computers.
This is where the problem might be occurring
#2 - Ethernet cable out of modem into my surge protector.
I will remove the surge protector from my setup and see if this fixes my issue.
I will let you know.
Thanks.
-
Kewl let us know what the ISP says.
As for the surge protector, that is possible. Again thats something in the loop that really isn't recommended as it can cause a drop in signal and possible drops and disconnects. Theoretically it shouldn't do much however like a splitter, it's something in the way and the less you have on the lines the better.
As for a better modem. If your ISP supports DOCSIS 3, I would get a Motorola SB 6120, It's the best they offer and I was just able to get mine last month. Been great a modem. I actually get good gaming signals now. Just ask your ISP if they support it as some may not at this time. It's supposed to be backwards compatible and I think it is but my ISP didn't support it so it wouldn't work 6 months ago so I had to wait. I love it now.
Let us know about the surge protector. Your cable should be clean and go from the outside box, inside to the cable modem then lan to the 4500 router, thats preferred. Nothing in between that.
-
I'm having a similar issue to you, and after some pokin' around I found out how to access the logs of the cable modem. In your browser, go to 192.168.100.1 (http://192.168.100.1). There should be a Login somewhere, and the default user/pass should be listed beneath it.
Motorola modems, and most cable modems I have ever delt with, don't have username and password. Just FYI as some good news. Also I know for a fact that the 5100 (unless the firmware was modified by the ISP to remove it) has that option. It will either look like

or
(http://i563.photobucket.com/albums/ss73/GenXXX/Screenshot.png)
Do you see the the tab listed as logs? Sounds like your stuck on the help tab.
-
Still waiting to hear back from Shaw.
Trikein there are no tabs only "Help" right in the middle where all the tabs should be.
(http://i131.photobucket.com/albums/p287/corpusmasochist/ModemScreen.jpg)
My connection has been up ever since removing the surge protector. The reason I included the surge protector was exactly the opposite of what you said Furry. I thought that including it in the wiring config that it would help prevent any loss or drops in signal. Isn't that what it is intended for?
-
Looks like that model may not support or have any user friendly menus like later model. As for the surge protector, it does just that, prevents a surge in excess power to connected devises, however not knowing how well the surge protector is built and what the specs on the cable circuitry do and allow. There is a possibility that the surge protector is introducing noise and or some level of signal level drop. Whos to know. I hope this might be the case and that the surge protector could be the point of issue for your internet drop. Keep us posted. Hope it works out.
-

No, it does. Looks like Shaw took it out of your firmware. If you bought that modem from them, I would be pissed. They...::grumble:: I shouldnt say more but this is becoming a trend with ISP and it is getting me very mad.
Now if you lease it, then yea, they can do what ever they want to it. I would ask to trade in your modem if possible. Try for a 5101U. Has the better chipset then that 5120 and newer firmware then the 5101 and don't have to worry about compatibility issues of the 6120.
Just out of curiosity, what happens if you go here (http://192.168.100.1/cmLogs.htm)
-
I finally got a return call from Shaw Cable and go figure the guy could barely speak English... Then to top it off I lost the phone call as I was on my cell phone. Talk about crappy luck.
He did say that there didn't appear to be any connection loss on their end but I don't think he even looked that much into it.
Plus when I asked about getting a different modem he said that the 5100 is the modem they use but he sounded quite uninformed.
I didn't buy this modem, Shaw gives their customers modems when they purchase internet.
Still connected 5 hours now. When I see 2 days that will be the longest in 2 months.
Curious to what happened as my system never had this problem up until a couple months ago. Maybe a something is wrong with my surge protector now?? Might be time to pick up a different one.
Oh and when I clicked on your link Tri it said "page could not be found"
-
Yes, that is the sad average state of technical support these days. A good friend of mine on PS3 has Shaw though, so I will ask him. Meanwhile. A quick glance on their support page says:
Found here (http://www.shaw.ca/en-ca/CustomerCare/InternetSupport/Residential/ResidentialInternetFAQs.htm)
I want to upgrade to High-Speed Warp or High-Speed Extreme from High-Speed can I swap my existing modem for a DOCSIS modem?
Yes. Simply bring your current Shaw High-Speed modem along with the power cable to your local Shaw retail centre to exchange it for a DOCSIS modem
So if upgrade to their Warp package, they give you a free modem. What stop you from upgrading, getting the modem, then downgrading the next day? Also, it looks like they even give you a free wireless gateway, with free installation if your a 3 Product user. I cant imagine them giving you a wireless gateway and not give you a new modem. Support for the 5100 on Motorola's website is discontinued.
-
Just curious if your ISP charges a rental fee for your modem? Some do and some don't. Mine does so I got rid of that soon as I found out I could get my own. I would look into getting the SB6120 if you can. For a $100, it's a great modem and seems to have room for growth. Over all I hope the issue was the surge protector and I would recommend if it maintains a connection, I would leave off the surge protector out of the network as to keep a good signal level between the ISP and your modem. This will help in troubleshooting later on as well. Remember KISS? ;)
-
I think they include the rental fee in the service charge. As in you can't stop paying it. I agree totally in taking the surge protector out of the equation. Also, if your looking for a new surge protector, I highly suggest [ur=http://www.newegg.com/Product/Product.aspx?Item=N82E16842111078]this one[/url]. Its rock solid, high joules, and most importantly, isolated filter banks. That means when the PSU from your PC dumps a huge draw on it, it won't cause a noise spike on the power going to your modem. Thats a big cause of T3 and other transmit errors on modems. I have one I use souly for my network equipment. Best 50$ I have ever spent.
-
You guys are truly awesome. The world should have more guys like you on it.
I have missed 2 call backs from Shaw today as they took to long and I had stuff to do.
I will try again tomorrow.
I am currently running Extreme Internet at $57.00 + 12% tax = 63.84
The Warp package is $107 + 12% tax a month = 119.84
The Nitro package is $150 + 12% = $162
I am a poor dude these days, I can barely afford the Extreme package.
Hmm, my next door neighbor is a Shaw tech I will ask him about getting a modem. I will ask shaw technical services first though then resort to my contacts if they deny me. heh...
I don't pay a rental fee for my modem.. I wouldn't do that, I would buy it our right if they tried charging me a monthly fee.
9 1/2 hours up and running... Woot!
Trikein's last post... I used to mess around with audio engineering and crossing patch cables over power cables was always a no no. Does that hold strong here as well? Stands to reason wouldn't you say. If you can keeping your network cables away from your power cables might avoid any "cross talk" or interference of any kind
Thanks for the suggestion on a different surge protector. As it is now I won't be running my network through a surge protector anymore.
"Remember KISS?" ----> Right on your furryNutz my friend.
-
Curious, what games are you fellas into? and are looking forward to playing?
Currently I play a lot of Bad Company 2. Years ago I used to be into Team Fortress Classic then Team Fortress, DOD, DODS, Counter Strike etc.. All the Valve games for that matter.
I personally want to play Brink http://www.brinkthegame.com/gate/?request=%2F, Battle field 3 (hopefully they remake BF2142 on the new BF3 engine. I also am looking forward to 2012 when Bioshock Infinite http://www.bioshockinfinite.com/ is released. I love the Bioshock story and scripts. Actually my favorite single player game ever. Great voice overs. Portal 2 looks killer as well.
So yeah many up and coming games I will be fraggin on for sure.
Maybe we can get together for a round or 2.
Cheers.
Corpus.

Wow, Canada is exspensive. We get 12 down, 5 up for 43$, 25down and 7 up for 53$ and 50 down, 10up for 100$. But anyway, if your not having a issue with the 5100 after resolving the issue with the surge protector, I would say get a new modem is you can, but don't go nutz about it. I mean diagnostics are important to me, but thats because I keep a eagle on them because I am in the buisness. To the adverage user, as long as everything is working, they don't care.
As for what games I am playing:
Starcraft 2 (though not as much after the last patch)
Fat Princess (PS3)
Red Dead Redemption
Little Big Planet
Halo Reach
Yea, as you can see, I have a mixture of intense games with simpler games. Depends on my mood. I got really burned out from RPG and FPS in my teens.
-

AC power is 60 hz - low audio. Cable is high frequency radio. The signals are so far apart in frequency as to be irrelevant.
Both AC electric and cable must connect directly to the same earth ground where each enters the building. Otherwise problematic voltages exist inside the building. Not only do both wires carry different frequencies. Problems currents on either wire are eliminated by connecting both short and direct to the same earth ground before entering. Visually inspect for that common ground connection.
-
If it ever drops connections, also can try downgrading drivers to the earliest for your network cards / wireless cards.
I had some pretty annoying connection dropping issues a while ago when I 1st got my DGL4500. Flashed to 1.23 and still had issues. I downgraded my wireless to the earliest drivers available and it's been solid since *i think* or at least better than b4 (which was dropping connection every couple days.
I also recently switched to a wired connection in my room to test things out and it's been dropping pretty bad and I downgraded my LAN to the earliest drivers. That also fixed my issues too.
So just keep that in mind ~ don't always upgrade to the newest drivers. They sometimes break things when trying to fix other features you don't use.
-
I'm currently into Halo Reach on XBL and most play on XBL. I do have Halo 2 on PC, Unreal Tournement 2003, All Diablo series and can't wait for Diablo III :P I also have BCBF2 and COD: WaW loaded.
-
Right on guys thanks so much for all your comments.
Unfortunately the loss of connection happened again about 7 hours ago so yeah I am thinking I am having some sort of firmware issues as I wasn't having any problems until the last couple firmware updates.
I agree updating your firmware doesn't always fix an issue cause other issues. From what I have experienced in the past anyway.
Where would I go to get previous firmware releases?

Very professional answer Westom.Thumbs up. Can I assume your a electrician? If so, can we call upon your expertise later in these kinds of matters?
-

Well you still don't know for sure its a issue with the firmware. I am more leaning to its the signal levels to the modem, which can change with a number of factors. Either that, the power to the modem, or the modem itself is dying. I cant think of anything that would make the router see the WAN connection disco. But if you want to back your firmware, try here (http://www.dlink.com/products/default.aspx?pid=DGL-4500&tab=3). You cant go before 1.21 I believe, unless you do a hard firmware flash, which is a pain(That reverts it to the firmware it shipped with).
-
Motorola modems, and most cable modems I have ever delt with, don't have username and password. Just FYI as some good news. Also I know for a fact that the 5100 (unless the firmware was modified by the ISP to remove it) has that option. It will either look like...
Actually, the modem I have (an Ambit), does have a password to get into the config and logs. Which is why I suggested it might have a "Login" somewhere in the corner. I almost didn't see mine. :) But good to know that's not standard.
-
Hmm, wow. Have seen alot of modems and never came across one that has a password. Good to know. Thanks
-
So I took my modem into exchange it which shaw technical support said they can do but the chick atthe counter refused to do it saying it wasn't compatible with the extreme service I have only with warp and intro. So she did give me a little newer modem the SB1502 but unconvinced I called shaw again when I got home. Another techi said yeah they can do that for me and said he would mail me the modem. But later left a message saying he made a mistake and confirmed that the extreme service is not compatible with the SB6120.
So. I am crap out of luck unless I upgrade to warp. Man that is a lot of cake for Internet. Extreme is expensive enough.
Now back to the new SB5102 modem, I have had one disconnect since connecting it yesterday. When these disconnects happen all the lights on the modem remain on so I really think it is the router causing the loss of connections not signal loss from the modem.
I will be clearing the FW and reflashing later today. Will let you guys know.
-
Nahh man, the 5102 is much better then the 5100. The 5100 was litterly the first DOCSIS 2.0 modem Motorola made. Fallows by the 5101, 5102,5120,6120,5101U,6180,6580 I think is the line. Technically there wrong in saying the 6120 is not compatible. All DOCSIS is backward compatible.<Edit out a whole bunch of stuff here on how and why> Basically they probably don't have a way to capp the bandwidth, which actually happened here in alot of areas when DOCSIS 3.0 first rolled out. Thats why the 6120 became so popular. You could pay for the lowest plan, get the 6120, and get simular performance of the higher plans. The ISP smarted up soon enough though. So now they either don't allow the 6120 unless you have the plan, or they implemented a method to cap it.
But yea, 6120 is great, but you did very well to upgrade to the 5102, if for no better reason you should (I hope) be able to see the signal levels and logs now. Sorry we put you through so much red tape.
-
Would be worth a try to go to radio shack and pick one up and see if it works or not. I did the same thing 6 months ago. Wouldn't work so I was able to take it back for a full refund. ;D
-
Trikein,with the 5202 I don't even get the "help" page now. Just a blank (done) screen appears. I was thinking about picking one up but I wouldn't know where to get it. Radio Shack here doesn't carry it.
I actually made a mistake saying I had one disconnect since connecting the 5102. I haven't. My connection has been up for 1 day 1 hour. Lets see if we keep going.
$120 a month for Warp is more then I pay for auto insurance. I want to upgrade but can't get my head around the price increase.
ACK!!
-
eeeks, what are you paying now and what speed is it? I'm pay $50 bucks for 10Mb down. Where abouts do you live. Maybe I can help you find a place that carries the 6120 if you want me to look.
Anyone of these places local in your city?

Ok, that gets me so ticked, I had to write a post about it. Hope you don't mind. If you do, let me know and I will remove it.

My monthly cost with tax is $67.84 which they say is a 15mbps plan but I usually get about 25mbps. Although earlier today I was getting only 6mbps. Sometimes it can fluctuate drastically. I just ran it again and got 18.31mbpa down and 0.94mbps up. So not so bad I guess. I am seemingly noticing since running this different modem to be a tad slower. Then again it might be slower going at this point in time.
As far as stores that I have close to me. Radio Shack for sure Wall Mart, and Best Buy. But I don't think they carry that modem and I am not sure I can run a modem I bought out right as they scan the serial number or MAC.. Some number that they use for they system to recognize the modem.. At least I think that is how it works.. But I might be mistaken.
Trikein do what you will man I don't care. You guys are the best 3some I have had in a long time.
Thanks again.
Corpus
Oh, Uptime 1 day 8 hours. Looking good. If my connection stays live then it was the modem after all.
-
Unless your ISP specifies that you have to run there modems, you can run your own modem as long as it meets there support specs and is supported by there systems. I think you have a good package for what your paying for and unless your doing a lot of downloading or what faster speeds, I don't see a need for going any higher. My 10Mb is really good for the speed and cost. I game, download and general Internet along with my roomie who works from home during the day. And that was before I added the SB6120. I think it's worth trying out the SB6120 and see if it works. I'm hoping it might. And you can just return it if it doesn't. Let us know man.
-
I think they have to use Shaw only EQ Furry. Atleasts thats what I gather from their DSLReport forum. And even if you could, looks like there having some big issues with DOCSIS 3. If I had to guess, its their traffic management system. Their infrastructure is under build and over sold, so when they get a push, they have to drastically cut bandwidth to get by.
And even if you could buy your own modem, they load their own firmware, which cuts out signal levels. I guess shaw goes by the theory "The less the customer knows, the better". That kind of attitude just pisses me off. But I have to also keep in mind this is a Canada ISP. They probably just do things differently.
-
I seriously can't justify spending an extra $50 to upgrade to warp. Way to much for what you get. I will stay with what I have which is expensive enough. But like you said Trik They do drastically cut bandwidth at times. My speed tests are all over the map.
-
Well hope the newer modem works better for you and the 4500 does well. Remember KISS and set up the 4500 well. It will help you keep your end of the network going for you. The ISP is a different matter. >:(
-
yeah, I'd like to know more about networking and getting things running fast and smooth

Yea, don't go to warp. They have some kinks to work out before the cost/gain ration is worth it. Your good where you are, as far as what they can offer atleast. :-\

Cableone 10Mb down, 1Mb up Cable>Motorola SB6120 Cable Modem>1ft Cat6 cable to DLink DGL-4500> 2ft Cat 6 cable to HP 24pt GB switch> All Cat 6 cables out to GB Lan cards on PCs that support it and another Gb switch in the living room for Dish Network and 2nd xbox. My first xbox is direct to the back of the 4500 using Cat 6. Other than this, all PCs are static IP on the 4500 along with a wireless AP. I don't use the 4500's wireless. All PCs aren't using any Gaming or Gamefuel rule accept my one gaming PC that connects to XBL that uses Gaming only. Both xboxes are using the game fuel rule listed in the sticky. The only thing I have changed is the ports, I've gone from using 65535 to 3074 as Tricky mentioned that using a global port for xbox could bring issues. I haven't seen any problems either way use either of the ports. Been happy with my system.
