I've owned the 655 for 3 months. Recently the DNS keeps failing on me (some website suddenly throws a DNS error) requiring me to do a ipconfig /flushdns as often as 10seconds. This happens to both wireless and wired connections.

I'm from Canada using Teksavvy.
Tried using default teksavvy's dns servers, or google's 8.8.8.8, 8.8.4.4 with no success
Tried setting dns server on my computer with no help
Experience DNS errors to all device that is connected to the network.
Tried enable/disable DNS relay
Using Rev. B
Newest firmware according to the router GUI

any thoughts?

I am not sure whether you are saying you have a network DNS error or a corrupted DNS data packet.  If you do a recursive ping, say for a 1000 pings to your DNS server do all requests look good.

Link>Welcome!

Link>What Firmware version is currently loaded? Found on routers web page under status.
What region are you located?
Are you wired or wireless connected to the router?
Has a Factory Reset been performed?

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.
Double NAT
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 router gets from the modem and put that into the modems DMZ.
Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask.

Some things to try: - Log into the routers web page at 192.168.0.1. Use IE, Opera or FF to manage the router.
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. This ensures each devices gets its own IP address when turned on and connected, eliminates IP address conflicts and helps in troubleshooting.
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.

Does this happen with all connected devices?
What browser are you using?

You can disable DNS Relay and manually input DNS server addresses into Setup/Internet/Manual. Save settings and reboot. You'll need to either reboot all the devices or /ipconfig flushdns.

[danieljai]

pings are fine when it works. Then all of a suddenly random pages will show DNS unresolved. If i do a /flushdns it comes back up.

What region are you located? Canada
Are you wired or wireless connected to the router? Wired to router. Wireless also exhibit same behaviour
Has a Factory Reset been performed? Yes, quite a few times.

Hardware Version: B1     Firmware Version: 2.10NA

What ISP Modem do you have? Stand Alone or built in router? Standalone router, no dhcp.
What ISP Modem make and model do you have? DCM476
No double NAT. The modem didnt have NAT capabilities, the WAN address is my public IP

Traffic Shaping is off
Advanced DNS Services is off
Enable DNS Relay is on
All devices has their own IP, so no conflict
Firewall is Endpoint to endpoint
uPnP and Multi-cast Streaming are both on.

I've tried manually input DNS with 8.8.8.8 or rely on obtaining default DNS from my ISP. Still has same problem.

It seems like I have all the things you've mentioned still no luck... just got an unresolved DNS googling again...

Ping by address not by name.

[danieljai]

does pinging DNS server address count? I also did 1000 ping 8.8.8.8 and 4% was timeout.

[FurryNutz]

Try disabling SPI as a test.

Try disabling SPI as a test.

It was never enabled

[FurryNutz]

Has the cable been swapped out between the ISP modem and router?
Does this happen if you directly connect to the ISP modem?

Was this working before updating to v2.10?

What browser are you using?
Try Opera or FF? If IE 8 or 9, set compatibility mode and test again.

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

No the cable modem has been the same nor switched out for the psat 3 months.

connection directly to the modem has been
I'm using chrome 23

who's "someone"?

[FurryNutz]

Try Opera or FF? If IE 8 or 9, set compatibility mode and test again.

Would be me if you need me to review your router settings.

[danieljai]

sure. What do I do? download and install teamviewer?

[FurryNutz]

download and either RUN or Install it. It's a self contained program. Lets set this up tomorrow.

[Hard Harry]

What is the DNS error you are getting? When it occurs, can you ping the domain? Does it return a different IP  when you ping and the site isn't working compared to when it is working?

[FurryNutz]

Any status on this?

I've got my 655 running with v2.10 at the moment.
I'm currently using manual DNS address entries and DNS Relay is OFF.
