Title: Dns issues
Post by: hortoristic on February 20, 2012, 10:02:13 PM
Some laptops on WI fi reporting bad DNS - but when I hard code DNS for Comcast - it starts working.  Seems to only be affecting WI fi not hard wired devices nor all the time

Is DNS relay still enabled?
How long have you been experiencing this condition?

How long have you been experiencing this condition?

I would run the following on each of the laptops: ipconfig /flushdns

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.

Turn off Short GI and Extra Wireless Protection if you have it. Under Advanced/Advanced Wireless.

I so appreciate your help.  I will check all this.

I'm still mystified why this router requires so much tweaking - other cheapo routers just plug and go - none of this reserved DHCP steps or other tweaks.

It does cover the house much better though.  Is it just a symptom of the firmware not up to snuff - why so much tweaking?

Im wondering if there is some sort of FW issue here. We might try and do a FW update using the Beta thats available.

I presume you have the initial FW version and haven't updated any?
