Title: Connection dropping on both DIR-655 and DI-604
Post by: elsporko on March 02, 2009, 08:30:30 PM
Alright, here we go  :-\ I bought a DIR-655 router a while ago and it worked great for a while, both wired and wireless. Recently, my connection started dropping randomly (anywhere from 2 minutes to 12 hours). Thinking the problem was my DIR-655, I tried different firmwares, factory resetting, messing with the QoS engine, UPnP, different IP ranges, turning off wireless completely, and it still happened. To get my connection back, I had to reboot my DSL Modem (Modem is a Speedstream 5200, and my ISP is MTS) as well as my router to get the connection back.

I switched to my old DI-604 router to test to see if it was my DIR-655 or not. The next morning, I woke up to find my internet down again. I rebooted my router, it was still down. Rebooted my modem, and it came back up. A few hours later, my internet dropped again, this time requiring a reboot of both the modem and router.

So, thinking maybe the problem is an old, flaky modem, I went to my ISP's store and got a new modem. Hooked it up with my DI-604, and it worked good for a while. About  2 hours later the connection dropped again. So right now, I've taken both my routers out of the mix, and am going straight from my modem to my PC. So far it hasn't dropped yet, but I'll have to wait a few hours/days to see if it stays up or not.

I'm at a loss of what to test next. I was thinking maybe it's a software issue with my PC, but I've had times where I've turned off my PC when the connection was up, and woken up with the connection dropped, so the PC wasn't on when it dropped. Anyone have any ideas as to what I could do? I'm going to phone my ISP soon and see if they can think of anything, but I'd rather fix it myself. Long post, I know, sorry guys  :-[

Thanks in advance, and I'm not sure if this is the right forum, but I couldn't find just a general help thread.

Who is the maker of the modem?

Are you running torrents?

Modem is:
Speedstream 5200
Part # 060-E270-A19
also has an Efficient Networks logo on the top left.

And yes, I do run torrents sometimes, but I doubt that's the problem. I've ran torrents before without it disconnecting, and it disconnects even if I haven't torrented in days.

Yesterday I connected my PC directly to my modem, and the connection didn't drop once in 21 hours and I was torrenting at max speeds the entire night. I just hooked up my DIR-655 again, hoping to find the problem. I just checked, and I have the timeserver option disabled.

Also a few minutes ago, I got the following messages (bubbles in the bottom right of the screen):
Local area connection 2 (my main connection through my router) is now connected. Speed: 1.0gbps
A network cable is unplugged
Local area connection 2 (my main connection through my router) is now connected. Speed: 1.0gbps
A network cable is unplugged
Local area connection 2 (my main connection through my router) is now connected. Speed: 1.0gbps
A network cable is unplugged
(These messages were about 1 second after eachother.)

and then it stayed connected fine. This is also weird, since usually the speed shows 100mbps, not 1.0gbps. When I went into Network Connections and disabled the LAN2 connection and re-enabled it, it switched back to 100mbps.

When you get one of those bubbles, does the router uptime reset?  (in which case, the router is rebooting).

If it is rebooting I recommend the latest beta b05.  (seems to have fixed my reboots)

I'm not sure if it's reset during that or not, but I don't think I've seen the uptime counter reset before (at least when my internet dies). I have noticed, though, when the internet goes down, where it normally says this:

Cable Status :  Connected
Network Status : Established

It stays like that. Despite me not being able to go online at all (or even ping an IP address, leaving out a simple DNS issue), it still says I'm connected. After I click the disconnect button just underneathe it, and try to reconnect, it can't, and says it's disconnected until I reset my modem.

Edit: Also, I've tried a few different firmwares, and I think I am on the most current one.

About 4 hours ago, I set my Windows XP PC to not get DNS and IP addresses automatically from my router (I still have it set to DHCP on my router since I usually use it with my 360 and Wii), and instead use a static IP, but use the router's gateway address. The connection is up and running, and I've had no troubles for the past few hours, so maybe it was just an IP conflict issue? Again, it's still too early to say anything, and I might just have jinxed myself :x I will leave it on overnight and see if it disconnects.

Moooooore to add, woot.

Parents phoned our ISP today, I was at school so I was unable to talk to them, but I had wrote them a few things to mention. I asked about what they said, and they just said that everything pointed towards a router problem.

So today, I just updated the firmware on the DIR-655 to the new 1.22 beta firmware, and set my PC to automatically get an IP from the router, and use specific DNS servers (doing everything I can think of at the moment ._.)

I left my PC on while at school and checked the logs of the router. One thing I see almost every time after it disconnects is this:

[INFO] Wed Mar 04 09:27:48 2009 Blocked incoming TCP packet from 71.60.37.49:43633 to 142.161.xxx.xxx:3992 as RST received but there is no active connection

There are a few messages with "but there is no active connection" after it when it disconnects. There were also a few new ones, though.

[INFO] Wed Mar 04 09:30:14 2009 Blocked incoming TCP packet from 118.136.8.51:30509 to 142.161.xxx.xx:3992 with unexpected sequence 447785366 (expected 4294901761 to 65536)
[INFO] Wed Mar 04 14:31:31 2009 Dropped packet from 5.116.216.100 to 74.52.201.106(IP protocol 17) as unable to create new session (quite a few of these near the most recent logs)

I've seen the IP Protocol 17 mentioned before on here for the same router, and he was having random disconnects as well? Does anyone know what this means?

The most likely cause is wireless hijacking or sniffing. Do a scan of your computer, uninstall wireshark, clean up your computer. It's not router issues, it's issues outside your router. IE: your doing it yourself unintentionally/Intentionally using packet sniffing / wireless hijacking software or someone else in your vicinitiy is.

Internet just disconnected. I checked my router's device info, and the connection uptime had reset, as well as my time (Jan31st 2004 D:). Cable status was connected, but the network status was disconnected and trying to re-establish. Underneathe, my IP address, gateway, and DNS all showed up as 0.0.0.0. I checked my logs, and found this (it's never said this before. Before when it disconnected, it never said any of this, maybe new with 1.22b?) These few messages repeated constantly. Resetting the router did nothing, and it just kept repeating. After resetting the modem, it connected right aways.

Sorry for the huge, constant posts guys. I'm really thankful for the help and suggestions, and I'm trying to provide as much info as possible.

@lotacus. Yeah, that's what I had assumed too at first. Although, the first thing I did when I started having this problem was simply turn wireless off, and it's been off since. Could this still be a problem even if wireless is turned off?

Also, We got some new phones a while back, so I just now disconnected all of them, they might be causing some sort of issue. Hopefully x_x

Edit: Disconnected :\ so it's not the phones. Put an old 1.10 firmware on it, now. We'll see how this runs ._. I'm running out of ideas. If I get a chance to, I'll bring my router to a friends place and see if it does the same thing to see if it's the router itself or not.

When you installed the Digsby Instant Messenger program, did you "unsubscribe" or decline from all their advertisment options?

check this out: http://www.downloadsquad.com/2008/11/24/new-digsby-installer-loaded-with-bloat-and-adverts/3

Now, it doesn't directly relate to the problem your having, but it is a possibility, that if you just installe digsby by blindly clicking next, next, install, yes, yes, etc, then you will not even know what malware was installed with Digsby.

You may also want to check out your Avast logs to see if it's dropping connections, or blocking needed processes required to maintain a connection.

With a computer name as Pwn, is someone concerning,

The line: [INFO] Wed Mar 04 09:30:14 2009 Blocked incoming TCP packet from 118.136.8.51:30509 to 142.161.xxx.xx:3992 with unexpected sequence 447785366 (expected 4294901761 to 65536)
 those malformed packets you are seeing from ip: 118.136.8.51 is from indonesia, which is also concerning, pointing at what your "internet environment" is regarding to your online habits.


You line: [INFO] Wed Mar 04 14:31:31 2009 Dropped packet from 5.116.216.100 to 74.52.201.106(IP protocol 17) as unable to create new session (quite a few of these near the most recent logs)
 is the router dropping packets being sent to Avast. For whatever reason it may be.

My suggestion would be to run another A/V program just incase Avast has been compromised, as well as download adaware S&D from www.lavasoft.com.

I would also hope that you obtained your software from a reliable source and one that has not been infected itself.

Run Adaware first and see if it detects anything. I would also hope that you are not infected with the conficker trojan. http://en.wikipedia.org/wiki/Conficker.

I've ran a scan a few days ago with Avast, Spybot, and Malwarebytes and didn't find much. I just installed Ad-aware, and I'll try out another antivirus program as well. Tonight, I'll reboot into safemode and do a full system scan all night with a few different programs and see if I can find anything.

I do remember something like that when I installed digsby, but I'm pretty sure I either said no to the different offers (Well, "offers" :P) in the installer, or I cleaned then up after installing. I've been on the fence between staying with digsby or switching back to trillian anyways, so I just uninstalled digsby to see if it affects anything.

Also, I checked Avast's logs, and the only logs I could find were of past virus scans and virus definition updates. However, just in case, I'll try uninstalling it as well and see if anything happens.

Since you swapped out your modem already, you may have an actual LINE problem, which isn't related to the router rebooting or anything.  When the connection/uptime resets, then that means it hasn't established an IP address.  So, one of two things can be occurring here. 

1) There is line attenuation, causing your disconnects, and you should ask your ISP to run some tests to see if the lines are corroded or something.  This can easily cause service interruptions.  It happens with DSL a lot!

2) Since you are using DSL, PPPoE is required to connect, and sometimes requires a username and password.  It may not, and if it doesn't, then make sure you set your "Reconnect Mode" to "Always On", and "Maximum Idle Time" to "0".  This way, regardless of activity, it'll stay on and not disconnect you.  I had noticed that it was trying to do "On Demand"...so of course while it's not being used, it would disconnect you.

Also, if you are going to set DNS servers, please set them in the router. 

If I also recall correctly, you should make sure that the modem is setup properly.  It's pretty much an entire gateway, with firewall and all.  Make sure that it's in bridge mode.

Hope some of that helps.

Since you've seen the router HAS rebooted I would continue down that road rather than jumping to wild and silly conclusions like you're being hacked over wireless thats not even turned on.

FYI, other torrent clients can keep your IP around for quite a while, and they can produce messages such as you were seeing, long after you turn off YOUR torrent program.  You may be able to confirm that (some of it) by checking your torrent port against some of the packets.  Either way its doubtful that external traffic is causing your problem.

I suspect whats going on is your router is rebooting, and then (for some reason) the authentication is unsynced between modem/router/isp requiring a reboot of the modem.  You ARE using PPPOE as your log states right?

I would continue to pursue eliminating or confirming this behaviour by tracking whether your router is in fact rebooting when this happens most/all instances.  You can probably do this by finding the event log ID on your PC for when it loses connection.

If that is the case then you want to fix the rebooting.  Im running 1.22b05 (just released a few days ago.. check the beta forum for links) and it fixed my remaining reboots.  (combined with simplified settings, turning off everything I wasnt using, or anything that I thought could be stressing the hardware).  As well you need to make sure your torrent settings are such that they wont cause reboots because of too many connections -- there's about 5 settings in utorrent that affect this.  Global connections is one, DHT is another.

Good luck

Just got back from my friend's place. I set up my DIR-655 there for about 4 hours without any disconnects. Couldn't stay any longer, so I packed it up and set up my DI-604. I'm leaving it there overnight, and I'll go get it tomorrow afternoon. If it disconnects, then it's a problem with the routers and how they're set up.

This morning I woke up and my internet was down on my PC, but it worked for the other PC on the network, so I unplugged the ethernet cable from my PC. If it's my PC causing the problem (as stated before, through things like torrenting and malware (I ran my PC in safe mode and ran AVG, Ad-Aware, Malware Bytes, and Spybot overnight and it was clean) ) then a format might be in order D: So right now I'm on my laptop wireless with my DIR-655, hoping my internet stays up.

Would it be possible that the problem is with DSL filters on my phoneline in my house? Even if the connection is fine directly to the modem, and it never drops when the phone rings. Could it still be a problem? Scrounging for ideas here >.<

Edit: With my laptop running ubuntu on wireless as the only thing on my network, it disconnected. I don't think it's the router resetting, since if it resets, then it says I'm disconnected from the network, and a notification pops up. When the internet gets disconnected, the connection uptime gets reset, but there are no entries in the logs mentioning it was reset, and none of the "You've been disconnected from the network" bubbles come up, since I'm still connected to it, the internet is just down. I think the points where on my XP PC it flashed the LAN2 connected, and then cable disconnected, etc, rapidly pretty much only happened when I actually reset the router (like for a firmware update), but it would connect and disconnect rapidly for a few minutes which is odd.

I'm sorry for being so hard to help, guys ._. but I really appreciate the help, since nobody else will give a suggestion other than "Buy a new router"

Hi elsporko,

Does your Friend also have DSL Connection?
Are you leaving your Computers on 24/7?
Could there be Noise on your Line?
Have you had the Telephone Company check for Line Noise?
Are you using a Static or Dynamic IP Address?
With all the changing around, have you performed a Factory Reset on the Router?
Are you using the Network Filter or Lock?

Could be the powersave on the NIC, disable all powersafe options to let the NIC run fullspeed all the time. Laptops limit the 'power' used by a laptop which makes it harder to (stay) connect(ed) when there's interference or a mediocre connection.

It's starting to sound like your connection to me a little.

You need more data under controlled circumstances IMHO.  I would eliminate wireless from the equation and try to build a baseline for what is actually going on.  Right now we're shooting in the dark.

-Yes, we're both on the same ISP, MTS, and both on a DSL connection.
-Nope, one PC is hardly ever used, and mine is on about 12 hours a day, maybe once a week I'll leave it on overnight
-I haven't thought about phoning them to check anything for noise, but I'll put that on my list of things to do.
-It's a dynamic address
-Yes, I've set it to factory default multiple times. Last night I set it to factory defaults, and disabled different options like QoS, UPnP, everything that I knew wasn't needed. It ran for about 13 hours until it disconnected. I reset the modem and it connected again, and then about 4 minutes later it disconnected again.
-By network filtering, do you mean MAC Filtering? If so, no, that's disabled.

@bluenote

For the most part, I've had wireless disabled. I only re-enabled it for a bit to go online with my laptop, to see if the connection would still go down with my main PC unplugged from the network. I've disabled it since then, once again.

Tomorrow I'll go check my DI-604 at my friend's place (Set it up wrong so it wasn't going to work in the first place >_<) to see if it's disconnected. I'll also see if I can get someone to come here and test the line to see if there's any noise or interference, which will probably be next week since it's the weekend. Is there anything else you guys would suggest to try and make this more controlled? I'll go unplug every computer from the network except mine, turn off wireless, reset it to factory defaults and maybe re-flash to the 1.22b firmware, and then disable some of the options on it.

Edit: Connection's been up for 23 hours now :o! Tonight I might connect the other PCs and see if it stays up. All I've done, like I said, unplugged other PCs and turned off wireless, reset to factory defaults, disabled things like UPnP, DNS Relay, Securespot, QoS, and set the WAN port speed to 100mbps instead of auto. Yesterday, when it disconnected after 13~ hours, I was streaming a couple of different videos. Today, I haven't torrented (in a few days), and I've kept downloading and streaming to a minimum, and it's been running fine. I do remember the last few times it disconnected I was downloading something, even if it was a small 10mb file on a site's FTP. Could this be pointing to the option that the router's getting overloaded with connections and it's somehow desyncing with the modem?

Might have found the problem! The connection was fine for over 24 hours straight with just my PC connected. During the night, I connected another PC and let it run overnight as well. In the morning, there were no problems and the connection was fine.

One of my parents went on youtube in the morning, and then it disconnected. They reset the modem, and then it was up again. Then, a few hours ago, I went on youtube as well, and within about a minute of watching the video, it disconnected. I reset the modem, and it was up again. Could it be whenever streaming a video, it disconnects? I tried to do it again about half an hour after resetting the modem. I watched about 10 minutes of videos and the connection was fine, no disconnects. A bit later, I tried again, and within about 5 minutes it disconnected again while streaming a video over youtube.

Could this be the problem? I imagine streaming videos like that takes up a lot of bandwidth, so could this be overloading the router? I remember, like I said before, a few times I was downloading a file and just as it was about to complete, it disconnected. I reset the modem and it was up again. I tried re-downloading the file, and again it disconnected. I reset, and then it downloaded all the way, and the connection was fine for a bit after that.

You didn't do a proper test then.  Just because you stream a youtube video, doesn't mean a whole lot.  Especially on the router.  What you should have done ALSO, is tested a youtube video with one computer plugged straight into the modem.  If it disconnects also, then you have a line problem. 

If it doesn't, then you have a router problem.

@Reinvented

When I had my PC connected to the modem directly, I did my usual thing. Watched a lot of youtube videos and also had a page from ustream.tv open most of the day, and then torrented all night without any problems. So yeah, it is a router problem, I'm just trying to figure out what it is :P. Could MTU have any effect? It's at 1492, the default, right now. Maybe set too high?

Normally when MTU is set to high, you'd get a lot of packet loss too.  It's not like are you having any issues resolving webpages, right?

You can try lowering it, till it gets stable.  Try increments of 4 or 8. 

If you are truly afraid that you had a bad flash, see if you can drop down to the previous version...maybe 1.21, and then reflash to the 1.22. 

When I had posted previously regarding the "PPPoE" setup, you never mentioned if you tried ANY of those settings I recommended you.

I did go over your post, and checked to make sure that the reconnect mode was set to always on, and maximum idle time (which is grayed out) is set to 0, so I'm not sure why it would say on demand. I also set the DNS IPs right underneath it, and disabled DNS relay. Also, the modem is pretty simple, and doesn't have any sort of setup or interface to my knowledge, so we always just plugged it in and it went.

Also, I set up my DIR-604 last night and tested streaming a video, and it disconnected right away as well. I got my DIR-604 back from my friend's place, and though it wasn't used much, it didn't disconnect. I'll go back there and try setting up a big download and streaming videos with both routers, now that know how to make it disconnect on purpose, and I'll see if it does the same thing. If it doesn't and it stays connected, then I will phone my ISP and see if I can get someone to check it out.

Edit: Well then, I feel smart :D *cough* It's a good thing you reminded me to doublecheck my modem, Reinvented XD. I just plugged directly into my modem, set up about 70 videos in my youtube playlist (leaving for work soon, figured I'd let it play while I'm at work), and started downloading two ubuntu ISOs (not torrenting, just regular FTP downloading). After about 8 videos, it disconnected, so the problem is with my modem after all? Weird how before I torrented all night and did my normal thing, and it went fine. I'll try and phone my ISP and see if they can send someone to check the lines and everything.

I feel smart now >.> ._.

Old lines and any sort of transfers or buffering can cause the connection to completely drop.  It doesn't necessarily mean the modem is bad, but instead you have bad lines.  Corrosion can interrupt transfers, etc.

So yes, definitely go and get your lines checked, and see if you can get them replaced. ;)

Agreed seems that way when there is a steady stream of data dropping the connection

this DIR-655 is a peace of junk, I used Belkin Pre-N for years and the dropping issue was hardly a problem until switching to this junk router.  I bought it because it got more security features than Belkin but didnt know it was this BAD

This is the best router I've ever had. Models used: Linksys (2), Asus (2) and... a Belkin. The latter s*cked big time. But hey, everybody's is entitled to their opinion.
