The Graveyard - Products No Longer Supported => Routers / COVR => DIR-645 => Topic started by: pdukers on April 06, 2012, 10:08:02 AM

I just had an issue where the router just stopped working:
- All wired pc's were unable to ping each other or access the internet
- Wireless also stopped working at the same time.
- Router did not respond to DHCP requests.
- Web interface of the router was unreachable.
- The power, LAN and WLAN lights on the router were still on.
I was not in the web interface making changes. A power off and on of the router resolved the issue, which lasted at least several minutes.
Hardware version: A01
Firmware version: 1.01
-
Some additional information.
I of course don't know if it is related, but about 15 minutes before the incident wireless was enabled on the router using the scheduling functionality of the router. A wireless device successfully connected to the router a few minutes laster.
Scheduled starting/stopping of wiresless was working without problems for about 5 days now since the last scheduled reboot of the router.

What region are you located?
Are you wired or wireless connected to the router?
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?
If this modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems.
To tell if the modem is bridged or not, look at the routers web page, Status/Device Info/Wan Section, if there is a 192.168.0.# address in the WAN IP address field, then the modem is not bridged.
If the modem can't be bridged then see if the modem has a DMZ option and input the IP address the 4500 gets from the modem and put that into the modems DMZ.
Some things to try:
Turn off ALL QoS or Disable Traffic Shaping (DIR only) GameFuel (DGL only and if ON.) options. Advanced/QoS or Gamefuel. Or set the QoS for manual and set the up and download links to match your ISP speeds you pay for. Don't use weighted.
Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual.
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.
What wireless modes are you using? Under Setup/Wireless/Manual.
Try single mode G or N or mixed G and N?
Channel Width set for Auto 20/40Mhz or try 20Mhz only.
Try setting a manual channel to a open or unused channel.
What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES, so you might want to try TPIK only or Auto.
Any other WiFi routers in the area? Use InSSIDer (http://www.metageek.net/) to find out.
Turn off Short GI, WLAN Partition and Extra Wireless Protection if you have it. 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. Cat6 is recommended. (http://www.networkcablingdirectory.com/articles/structured-network-cabling-id_1151.htm)

Yes I would set up for single mode G and test this out.

I don't see any newer or beta FW for your unit for your region at this time.

I switched to G only and will test it.

There are about 13 other wifi routers present, but I am the only one using channel 13 at the moment.
Do you think it is possible that something going wrong in the wireless part of the router can freeze the whole router?
-
If you have 13 other WiFi routers near by, this is probably a cause of the issues your seeing. Are they all on 2.4Ghz? Your area is probably experiencing WiFi congestion on 2.4Ghz.
-
Yes, all 2.4 GHz. Only one of those routers also has 5 GHz enabled.
-
Whats the chance of you testing or getting a 5ghz supporting router and testing your PC with 5Ghz wifi USB adatpers? I bet your problems would go away if you moved from 2.4Ghz to 5Ghz.
-
Not an option. I already did a test with a 5 GHz router before I bought the DIR-645 and found out that the range I got was not good enough for some parts of the house.
-
Well only other think you can try is to lower the power output of the WiFi from High to Medium and see if this might help. This will lower the radio foot print and maybe help with the interferences your experiencing.
Try to find a open channel and set it up manual for that channel thats not being used.
I would try 5Ghz and also get a 5Ghz AP or extender in parts of the house that you need WiFi on using 5Ghz.
Your problems are going to probably continue while using 2.4Ghz and all the neighboring 2.4Ghz radios around you.
Good luck.

Hi,
I have a similar problem with my DIR-645. I also use scheduling for wifi. Every couple of days the router will not activate wifi as it is supposed to and sometimes wired devices do not have internet access any more. After reboot everything is ok again. Unfortunately, I loose all log entries because of the reboot.
I start to believe that scheduling is buggy on this device. There is another thread reporting similar problems: http://forums.dlink.com/index.php?topic=45699.0
I will disable scheduling completely and see if the problem still occurs. To me it looks like a bug. Is there any place to open a ticket with dlink?

Any router log indication of loosing or re-establishing connection with isp modem during this time frame?
Does ISP offer any log viewing abilities?
Is the ISP cable line a dedicated internet line or does it also provide television services?
If so, make sure there aren't any TV line splitters on the cable line. These will lower the signal going into the cable modem. If you need too, use a One good quality one.
Check cable between Modem and Router, swap out to be sure. Cat6 is recommended. (http://www.networkcablingdirectory.com/articles/structured-network-cabling-id_1151.htm)

Thank you for your response.
As I mentioned above, my logs are lost whenever I have to restart the router. I use the cable only for internet.
I don't think these factors matter for the problem. Even if the router looses the connection to the modem I still should be able to access the router's management page.
There is a timely correlation to the scheduling. The router never stopped working during regular operation. It was only in the morning when it was supposed to activate wifi. I turned of the schedule now to see if the router becomes more stable.

Keep us posted. I'll try this when I get home. Can you provide a scheduling time frame and how your setting it up so I can replicate your condition?
-
Sure. I use 7 AM as start time and 12:30 AM as stop time.
I just realized there is a firmware version 1.02b11 available on dlink.de (on dlink.com 1.01 is still the latest version). I will give this a try before disabling the schedule completely.

Follow the FW update sticky in the FAQ forum for doing the update.
FW Update Process (http://forums.dlink.com/index.php?topic=42457.0)
Keep us posted.
I set mine to turn off at 2am and on at 2pm, I'll try your settings as well.
So you leave your wireless devices on while the wireless schedule is in effect and then when you come back you can't connect as the wireless seems to be not enabled?
-
My router has now been running normally for 2 weeks now with a daily scheduled off/on of the wireless part. Maybe it helped setting it to quiet channel, but it is hard to diagnose when the issue can't reproduced at will.
-
Glad yours has been running well. Hope you enjoy it.

And it stopped working again :(
My brother is visiting and made a wireless connection with his phone and laptop. It worked for a few minutes and then the router stopped responding again like before. Only a power off/on solved it.
And the router password was also blank after the power off/on.
-
I played for 6 hours on XBL yesterday. Xbox was wireless along with my Mac Book and iPhone connected. Didn't see any issues until the wireless schedule kicked in at 3pm. ::) I'll change it tonight to match yours.
Got 300 on the xbox and 130 with Mac Book. Overall it was good yesterday.
Maybe someone can review your router settings with you using teamviewer (http://www.teamviewer.com) if your interested. Its safe and secure.
-
So set my 645 up yesterday for 7am and 12:30am and I got up yesterday am before the 7am kick off time and I could not access the WiFi, I checked the WiFi indicator and it was OFF. I came home yesterday afternoon and checked the WiFi and it was ON and I could gain access just fine. I changed the schedule for 6am to 2am last night. I checked this morning when I got up and I had internet. I presume it shut off during the night at 2am since I went to bed at midnight and came back on at 6am.

Unfortunately the problem does not occur every day. I ran 2 weeks without problems and now I had the problem 2 days in a row. But when it happens it is a few minutes after the WLAN part gets activated.
I will send you a PM with a link to my router config.
-
One thing I'd like for you to test for 2 days if you can, turn OFF the wireless radio and just test wired and see if any problems arise while wired to the router. I'd like to isolate this to the wireless if possible.

Ok. I will keep the wireless part disabled for some time.

I loaded your config and took a look:
I see your running G mode only? No N?
I would turn SPI back ON.
I would also enable the rest of the 3 ALG options. Those should remain enabled.
Other than this, all seems ok. Maybe we can have a review live sometime at your router settings. How has it been running? I played xbox for a bit last night. Router was fine.

My router has been running for 3 weeks now without problems. So I believe the scheduler problem is fixed in firmware version 1.02b11.
Here is the link to that version: ftp://ftp.dlink.de/dir/dir-645/driver_software/ (http://ftp://ftp.dlink.de/dir/dir-645/driver_software/)
Sure. I use 7 AM as start time and 12:30 AM as stop time.

Be advised that the version you posted is for EU or a german version of these routers and not for NA units or supported on NA units. Glad its working well for you. Enjoy.
-
Ok. I will keep the wireless part disabled for some time.
No problems with wireless disabled. I think I will try the 1.02b11 firmware too. Should not be aproblem since I have European version of the router.
-
You may have some sort of wireless interference if the router works well with the wifi radio turned off, let us know how the beta works. Been using the NA version here and its good so far.
-
I have successfully upgrade to v1.02b11. Now wait and see.
-
Keep us posted. Only thing I see and maybe its a configuration issue on how I have scheduling set up, however I noticed that when using schedule for WiFi, setting up monday thru friday, 6am to 1am, it works however on the weekends the WiFi is being turned off when I haven't selected the weekends. Let us know your experiences with WiFi scheduling.
-
I have successfully upgrade to v1.02b11. Now wait and see.
And it already stopped responding again ... that was quick.
Only test I can think of right now is to turn off scheduling and keep wireless enabled all the time.
-
give that a go, I've got mine set to a schedule, all week 6am to 2am. Been working so far.
Let us know what you find out with Schedule OFF.
-
No issues with WLAN enabled all the time for 13 days. Then the router unfortunately got rebooted because of a power outage in the area I live. Has been running fine again for another 5 days.
-
Ok, now is the wireless scheduling working for you? Glad the Wireless is working at this point.
-
I will set it back to scheduling again.
-
Keep us posted. Mine was working fine the last time it was online.
