The Graveyard - Products No Longer Supported => Routers / COVR => DIR-825 => Topic started by: lagonauta on November 11, 2012, 08:27:31 AM

Hello, yesterday I just did one lan party here at my home and had a very annoying problem that took me some time to workaround albeit my solution was not ideal.
There were 6 computers on the 2.4GHz band, and 2 on the 5GHz.
Everytime the people on the 2.4GHz band would get disconnected for no reason, but this router should be able to handle that number easily. After lots of fiddling, like telling people to shut down their phones WiFi, I finally found the culprit:
N and G mixed mode
Even with only Wireless-N devices there would be problems. N-only mode worked well.
That is unpractical for me as there are some devices here that are still on Wireless-G, like game consoles and some phones.
Sadly I did not test G-only mode, but that would be too slow.
My old DIR-615 could handle more than that on mixed-NG with no problems
PS.: I only use 20MHz on 2.4GHz.

Link>Welcome! (http://forums.dlink.com/index.php?topic=41537.0)
What Hardware version is your router? Look at sticker under router.
Link>What Firmware (http://forums.dlink.com/index.php?topic=47512.0) version is currently loaded? Found on routers web page under status.
What region are you located?
What ISP Service do you have? Cable or DSL?
What ISP Modem do you have? Stand Alone or built in router?
What ISP Modem make and model do you have?
Some things to try: - Log into the routers web page at 192.168.0.1.
Turn off ALL QoS (http://vonage.nmhoy.net/qos.html) or Disable Traffic Shaping (DIR only) GameFuel (DGL only and if ON.) options. Advanced/QoS or Gamefuel.
Turn on DNS Relay under Setup/Networking.
Setup DHCP reserved IP addresses for all devices ON the router. Setup/Networking
Ensure devices are set to auto obtain an IP address.
Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall.
Enable uPnP and Multi-cast Streaming under Advanced/Networking. Disable uPnP for testing Port Forwarding rules.
WAN Port Speed set to Auto or specific speed? Some newer ISP modems support 1000Mb so manually setting to Gb speeds can be supported by the router. Advanced/Advanced Networking/WAN Port Speed
Link>Wireless Installation Considerations (http://forums.dlink.com/index.php?topic=48327.0)
Channel Width set for Auto 20/40Mhz.
Try setting a manual channel to a open or unused channel. 1, 6 or 11. 11 for single mode N if the channel is clear.
What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only and has the best performance.
Any other WiFi routers in the area? Link> Use InSSIDer (http://www.metageek.net/) to find out. How many?
Turn off WISH, and WPS under Advanced.
Try turning off Short GI, WLAN Partition,and Extra Wireless Protection if you have it. Under Advanced/Advanced Wireless.
Enable WMM Enable (http://forums.dlink.com/index.php?topic=50738.0) Under Advanced/Advanced Wireless.
Turn off all anti virus and firewall programs on PC while testing. 3rd party firewalls are not generally needed when using routers as they are effective on blocking malicious inbound traffic.
Turn off all devices accept for one wired PC while testing.
Check cable between Modem and Router, swap out to be sure. Link> Cat6 is recommended. (http://en.wikipedia.org/wiki/CAT6)
I also highly recommend gaming over a wired connection. I've personally haven't had that many gaming over wireless, At most I think some uses have done 2 or 3 devices.
One thing you should check out and maybe use is the 645/835 Gaming and Gamefule settings for XBL if your using any online services in the FAQ Library (http://forums.dlink.com/index.php?board=302.0).
Keep us posted.

My router is one DIR-835 A1, with firmware 1.02.
My ISP is Primus Canada, DSL.
The modem is with built in router, but it is bridged right now. Thompson TG585v7.
I set the wireless channel manuallyto 1 (it was on 1 already, but automatically) and was still having problems.
I only use 20MHz channels and WPA2-Personal with AES.
WLAN Partition is already off. WMM is forced on.
But I just noticed that changing Short GI to disabled and saving does nothing, when I go back to its page it is enabled again. Anybody can reproduce?
WPS is always disabled.
The lan party was for playing Age of Myhology, but the problem was that the router couldn't sustain 6 simultaneos clients, those clients couldn't even authenticate with the router.
It worked fine on 802.11n mode only, but on mixed-NG it did not (even though there were no G clients connected)
-
Channel Width set for Auto 20/40Mhz.
-
On Auto it stops working with 2 wireless-N clients when just one wireless-G client connects.
On 20MHz it works with up to 6 wireless clients, be them N or G.
My router is always set for 20MHz-only on 2.4GHz, as I want it to be neighbor friendly.
I have a hunch that the problem is the "Short GI" that I am unable to disable :/
-
According to my router the firmware 1.03 is up, but I can't see it on the website.
What was changed?
-
Can't find it on any site either. Not sure whats changed.
I would go ahead and load it. You can always downgrade if something happens.
I recommend following this:
FW Update Process (http://forums.dlink.com/index.php?topic=42457.0)
Where it says you need to download the zip file from the main web site, just replace that step with using the routers web page. Please do a factory reset both before and after the udpate. Then configure from scratch using the web page.
Please use IE for FW upgrade. Try using FF when configuring after.
-
http://ftp.dlink.ru/pub/Router/DIR-835/Firmware/DIR835A1_FW_ReleaseNote.txt
It seems that not much was changed, but will update anyway when I get home.
-
Odd that it hasn't posted officially to the mains yet. I suppose. Not sure if that info is the same for NA units or not.
If the router says theres new FW, then give it a go and let us know.
-
Got home, connected the cable and... the ports are now fried. Maybe D-Link forgot to put some circuitry to prevent short circuit or something when connecting any cable. I can access the router through wireless but now the WAN and the LAN ports are dead.
The port on my computer still works, also on my modem.
Good thing that I bought it less than 30 days ago.
-
Was this after for before trying the FW update?
Power OFF the 835 for 30 sec. leaving it unplugged. Power OFF the PC that you were using to wire connect.
Try a factory reset.
Does anything recover? I had one of these and didn't see these issues. Only thing that might fry the LAN is improper connections or maybe a mis configuration in the network cards management options on the PC. Or a bad cable.
-
It was before trying the FW upgrade. I left it and my computer resting for 5 minutes but did not work.
Tried a factory reset, the SSID got back to "dlink" and "dlink_media". I could connect to it wirelessly, but couldn't access the web interface.
Pluged in the cable, did not work.
I just exchanged it for another unity, will test it for some time now.
-
Keep us posted. Use IE or FF when configuring the router.
Maybe someone can review your router settings with you using Link> teamviewer (http://www.teamviewer.com) if your interested. Its safe and secure.
-
Updated to 1.03.
Still unable to disable Short GI, but will keep testing.
-
I would contact level 2 support and ask about this. I think I remember seeing this on my 835 when I had it. I can't remember if I was able to turn it OFF or not. I'm wondering if there is a setting that is dependent upon being switched to be able to get Short GI to be disabled.
Are the wired LAN ports working now?
Let us know if you want someone to review the router settings with you.
Keep us posted.
-
When I noticed that the ports died, I also noticed that the router was very hot on the base (it was standing horizontally).
Now it is vertically positioned and seems to be running cooler, it also seems to be more stable. This weekend we are planning another LAN party, will post here if it goes without any problem. Did the other people that had problems with this router say if it was standing vertically or horizontally?
Maybe this router has some overheating issues? I keep the room where it is located at 25C (77F), for some it may be too hot but I am used to hot climates making it very comfortable to me.
I just hope that it works well in my country where it is fairly common for the temperature get to 35C (95F).
-
I had mine runing in both H and V positions. I didn't notice anything while using H however I didn't have a a lot of traffic going on like you do. I'm the only gaming in my house and during the day, roommate works from home so mostly general internet and some VPN stuff going on. So I might not have noticed it. I know we are tracking a temperature issue over on the 857 forum. The newer routers do run a bit hotter however if there are some differences between H and V positions, might need to let D-Link know. Can you look at the user manual and see if there is operating temperatures listed?
I would turn off options like WPS, WISH and options that you don't really need. Helps the router run lean and smoother sometimes. Use Specific Wifi modes like before if you don't need A or B modes.
Wire connect those devices that can be wired connected. IT's preferred specially for gaming.
Keep us posted on how it goes.
-
Also, the ISP modem, there isn't any WiFi enabled on it is there? Just checking.
-
The operating temperature goes from 0C (32F) to 55C (131F) according to the manual.
WPS is always off (too insecure and I never used it anyway), there is no WISH (I am starting to think that DIR-835 is lower-end than DIR-825).
Using NG on 2.4GHz and N on 5GHz. Medium transmit power on 2.4GHz and Low on 5GHz.
Using PPPoE to connect to the internet.
IPv6 is enabled with one HE tunnel, IPv4 and IPv6 firewall are up.
UPnP is active, media server and storage is off (USB is not being used). HTTPS is on. Guest network is off.
QoS is on (QoS configuration page is the same as the one for DIR-615, maybe the DIR-835 from Canada is different?)
Sadly I cannot connect any computer to it by wires as the router is in my bedroom and there is no way to put cables trough the walls.
The ISP modem is on Bridge mode and WiFi is disabled.
Will keep testing.
-
If you could do me a favor and capture the QoS page and post it here if possible when you have time. I'll adjust the stickies to reflect this.
Does the QoS section look anything like this?
Gaming and QoS for XBL (http://forums.dlink.com/index.php?topic=42011.0)
How is the WiFi on the newer 835? Still acting up or working better? How many devices are connecting wireless while gaming? Could be running into a threshold limitation maybe.
One suggestion if you are interested, run 1 long LAN wired from the bedroom where your router is and run it out to where most of your wired devices are located. Get you a external Gb network switch. They make them from 4 ports all the way up to 48 ports. I have a 24 and a couple of 8 port units. Put the switch near your wired devices then connect them to the switch. Will run smoother if you can use this platform. I use a 50 ft cable that runs from my office to the living room where my 8 port is.
Keep us posted.

Here:
http://img832.imageshack.us/img832/8214/dir835qos.png
The wireless connection seems to be working better, with four N devices on 2.4GHz (and sometimes one X360 Slim (N) or one 3DS (G)). On 5GHz there is only one device.
Do not know if this is because of the unit, or because of the new firmware.
I played online only with the 3DS and it seemed to work fine. This weekend I should be able to test it for real, maybe lots of small packets on the network from LAN gaming saturate the router wireless processor.
(6 computers and 4 phones on 2.4GHz + 2 computers on 5GHz)
If it still gives me problems I might do what you suggested, just need to measure how long the cable should be. Ugly, but certainly effective.

Thanks for the image. This wasn't what I saw, maybe they are different or they changed it. Crazy. One thing, I recommend disabling Dynamic Defrag. Thats for slow ISP connections. Isn't needed.
So you can review this:

One other suggestion, if you want to use more devices on 5Ghz, get you a DAP-1533 and connect them to it and bridge that 1533 to the 5Ghz on the 835. This might also help alleviate the load on 2.4Ghz radio.
If it still gives me problems I might do what you suggested, just need to measure how long the cable should be. Ugly, but certainly effective.
I agree, I have cables running back and forth from the office to the living room. I use those little brass round hooks and run the cable up and aroudn door jams and frames, putting the hooks up towards the top corners of the door frames then down as close to the floor as possible. This does help clean the wire runs up a bit.
If your concerned about router cooling, I bought one of these:
Onn Laptop Cooling Pad (http://www.walmart.com/ip/16794998?adid=22222222227000862257&wmlspartner=wlpa&wl0=&wl1=g&wl2=&wl3=13695380590&wl4=&wl5=pla&veh=sem)

Just noticed that the logs are flooded with name server messages, even when there is almost no activity on the router. Is that normal? I just had a major slowdown for some seconds and it seems to be related to them but that is a hunch, the router's config page was slow to navigate and websites were slow to load.
1 client on 2.4GHz and 1 on 5GHz.
Router has been running for 2 days and 3 hours with not very much traffic.
The slowdown stopped by itself. The logs are registering "System activity" and "Debug Information".

Seem like the router or ISP modem is trying to do something.
Is DNS relay and Advanced DNS Service enabled?
ISP Modem still bridged?
Try this, use either your ISP DNS or Google DNS, input the primary and 2ndary DNS into the Setup/Internet/Manual/DNS. Apply then DISABLE DNS Relay. Save and reboot. You might have to restart the PC so it gets it's DNS cache cleared.
Check the logs again, still see the message? You shouldn't be seeing this flood of messages.

Router's wireless just stopped responding when 6 clients connected on 2.4GHz, there is some kind of serious firmware driver bug here. It was still working on 5GHz and probably wired.
I put one rotuer from the competition and it is working fine now, but I really like D-Link routers and I would love if this bug were fixed.
DNS Relay was active, and advanced DNS disabled.
ISP modem still bridged.
Tomorrow will try this fix as I can't to it right now.

'I put one rotuer from the competition and it is working fine now, but I really like D-Link routers and I would love if this bug were fixed.' - What is this in regards too? Using a different router?
Possible there is a problem with FW and handling of 5 or more 2.4Ghz clients. One thing you might try, Turn OFF the 5Ghz radio and see if 2.4Ghz exhibits the same. If so, I would recommend you phone contact D-Link support, level 2 or higher. D-Link needs to be made aware of this problem. I might also check this router out at a different location, friend, neighbor or family members place and see if the problem follows just to make sure your external environment isn't interfering.
I think in mean time, if you can get as many devices on wired connections or use the 5Ghz radio for now, this should keep you going until D-Link comes up with a solution for the 2.4Ghz problem. Be sure when you call them that you have all the information, test details and such to give them so they can determine the best course of action. Let them know if you've tried different routers, radio modes and configurations and such. Any InSSIDer information and if other WiFi is near by. The more information they have the better they can figure out what needs to be done. Can refer them here so they can see what we've tried here as well.
Keep us posted please.

With the different router it worked perfectly, in the end I counted 10 clients on 2.4GHz and 4 on 5GHz. This router is at the same price range as the DIR-835.
Next weekend we are planning to have another LAN party, and I will try disabling 5GHz.
How can I contact D-Link support? Is it written somewhere on the box?
I couldn't test disabling the DNS Relay yet, but will do when I have the time. Would it reach the NAT table connection limit? I am just imagining 10 devices making lots of DNS queries at the same time while one is torrenting.

Please phone them and talk to level 2 or higher for this one. Tell them that you've done all the troubleshooting, mentioned trying a different router seems to resolve your problem using same clients.
May I ask what other router worked for you? Just curious.
I'll pass this along to my contacts as well here. I believe that this router should be able to handle more than 4 or 5 devices on wifi at a time. ::)
Please let us know how it goes.
-
I did not know if I was allowed to post its name here. It is one WD MyNet N750.
Feel free to edit my post if I should have sent to you by PM.
I will test 2.4GHz only this weekend, and then I will call them. What are their working hours? I am at GMT -5.
Should I call D-Link Canada or US? The one from US seems to be more organized as it has more than one phone number.
-
No thats ok. just need to know. Not trying to hamper any competition. Where here to help you determine whats going on and best course of action. it does help to know that a different similar router is working so this give DLink a bit more information and hopefully will review it and fix it soon. Ya we all like DLink, so we do want to help them improve and let them know if any problems we find. Troubleshooting using other routers is desired and once all that has been exhausted, then it should help D-Link to find a solution.
I would call the U.S. I don't think it should make any different unless they are going to do an RMA or something like that. I don't think an RMA is needed here, rather something in FW needs to be done. I don't think this problem can be fixed by and RMA since you have tried it one 2 same model routers that exhibit the same thing. Are there any other D-Link model routers available there? It would be interesting to see if you could test say a DIR-857, or 827. I suppose i can try this on my 857 this week. I need to see if I can bring up that many wireless devices. I only usually have about 3-4 at a time online. I'll see what I can dig up and test to help this out here.
Thanks for your patient, efforts and time in this. I hope D-Link will be able to resolve this.
Keep us posted.

Sadly I am the only one here that was willing to buy a router, all the others are using those modem + router combo from their internet provider.
Besides that, I do not have the money to buy another router to test. Lucky me I had just received some temporary money so I could test both routers the same time. I have 20 days to decide which one I will return, and I hope it is not the DIR-835.
-
No worries, I have forwarded this on to my contacts here. Please phone in as well.
I'll gather up all my devices and see what the DIR-857 can do. :D

Ok so I tested my DIR-857 Rev A1 v1.02, Mixed ALL modes, Mixed G and N and N only, Auto 20/40Mhz, Channel 11, WPA2 and AES only and i'm able to get 7 devices connected on 2.4Ghz all at once:
Started with 5 on 2.4Ghz and one on 5ghz to monitor wireless status:
(http://i1195.photobucket.com/albums/aa396/furrynutz740il/Screenshot2012-11-19at44855PM.png)
6 Devices connected on 2.4Ghz:
(http://i1195.photobucket.com/albums/aa396/furrynutz740il/Screenshot2012-11-19at45010PM.png)
7 Devices connected on 2.4Ghz:
(http://i1195.photobucket.com/albums/aa396/furrynutz740il/Screenshot2012-11-19at45529PM.png)
The only thing that I noticed is that one device with a DWA-131 does not connect using single mode N for some reason, this maybe a DWA issue not related to the router as you can see it's the only device connected in G mode. Other then that, all 7 connected and internet or network testing passed.
Devices used:
Mac Book Pro, iBook G3 using a DWA-131, 2 iphone 4s's, 2 PC's using DWA-160's, and a xbox 360 using a 2.4/5Ghz wireless adapter.
I hope this will let D-Link know that the DIR-857 supports more than 6 devices. I presume the DIR-835 should as well.
-
Just a quick update:
DNS name server is still flooding the router's log. For now I will leave "System Activity" logging disabled.
-
Are you using your ISP DNS or something else? I would try using Googles Name Bench app and see if you can find alternate DNS. Input that into the router and turn OFF DNS Relay.
-
I enabled and then disabled DNS Relay and now it is not flooding the logs :)
Maybe the config got lost somehow.
I also disabled DHCP always broadcast, I believe that all my devices should work with it off. Here is hoping that those two options were causing all the problems...
I am now using Google's DNS.
-
Keep us posted. Have you been in contact with DLink support about the wireless problem yet?
-
Not yet, I plan testing with only 2.4GHz active and then calling them. I might call them tomorrow morning if I have the time as I think that it won't make much of a difference.
-
It might not get any quick resolution however it will bring this to there attention. The more they know about it the more they will be apt to get a fix going for it.
Keep us posted.
-
I couldn't test it this friday night, our LAN party did not happen :/
Will try calling them anyway when I can.

Not sure if this will help any. Might be worth a try. There isn't any release info on it so don't know what it fixes. :-\
