Router is not the problem...
« on: February 23, 2012, 06:47:25 AM »

I have a unique issue here because having router issues that is definitely not the routers fault, and most likely not the modem's. I currently have a DIR-655 in place here but have gone through 4 routers and 2 modems trying to resolve this problem.

When this all started in October last year we were having trouble staying connected to a terminal server and would lose access to its URL which is set up with DynDNS. We switched service providers and all was well for a wile until our wireless started to drop, at the time we had a Netgear VPN and a Netgear Access point, and the network would just drop until the router was rebooted, sometimes 2-3 times a day and it would become a morning ritual to reboot the modem/router first thing.

We removed the Netgear AP and turned on the wireless on our VPN and tried that along with a new modem, no help, we replaced both with a Cisco VPN with wireless, no help, we migrated to a software vpn solution and installed the current D-link router and the next day the same thing happened, I then replaced the power strip that was feeding the router and modem and that fixed it! We were good for months!
but now the issue seems to be coming back, not as bad as before but still a lot more frequent than is acceptable.

Does anyone have any Ideas? Something I can try? Am I wrong in thinking it is power related still? I am about to put them on a UPS system but it doesn't seem like anything else is affected by any power oddities in the building...we have about 5 PCs on wireless and 2 wired printers and nothing seems to be affected.
Any help is greatly appreciated.

What Hardware version is your router? Look at sticker under router.
What Firmware version is currently loaded? Found on routers web page under status.

What ISP Service do you have? Cable or DSL?
What ISP Modem do you have? Stand Alone or built in router?
What is the current ISP Modem make and model# do you have now?
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.

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.
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 mixed G and N?
What security mode are you using? Preferred security is WPA-Personal. WPA2/Auto TPIK and AES. Some WiFi adapters don't support AES, so you might want to try TPIK only.

Any cordless house phones?
Any other WiFi routers in the area? Use InSSIDer to find out.
Turn off Short GI 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.

Maybe someone can review your router settings with you using teamviewer if your interested. Its safe and secure.

Thank you very much for the reply, sorry I am so late getting back to you.
I have the B1 hardware version and 2.0 firmware version and am running mixed wifi modes, I am running on channel 11 which I have heard is the best channel for N networks (although I believe all our adapters are B/G)
There are no cordless phones in the area as far as I know and only one other wifi network nearby and it is on a different channel
the current issue seems to be that the router stops broadcasting wifi and wont start again until the router is restarted. this currently is very infrequent and hard to troubleshoot.

Changed from Mixed mode to Single mode G.

Any other WiFi routers in the area? Use InSSIDer to find out.
