didn't do it! but disabling WISH did though!

i was skeptical, but i've had 9+ days without lockups since disabling DNS relay.

Is this a memory leak issue with DNS or a physical memory limitation with the new Kernel?  With any DNS cache algorithm, you should be aging DNS entries and pruning that cache frequently.  This is especially true when you have limited memory, like on these little routers.

So, to me this looks like some fundamental issue with memory management on the box.  This is especially true if by disabling the DNS relay, it does not clear up the issues for everyone.

My guess is that there is a general memory problem, and DNS is the largest consumer of available user/system memory.

Firmware 1.21 had an issue with DNS Relay that was referred to as "DNS Slowdown" (you can do a search).  This was fixed in a beta firmware 1.22B05 and rolled into 1.31.  It would be interesting to see what the original problem is and what the fix was.

yea, very familiar.  if i had the source, i would fix it too.

I have A4 hardware and 1.22 FW.  Was regularly having drops.  109 days without a lockup and still counting since disabling DNS relay.  Was only change I made, so absolutely no doubt that this fixed the lockups.

I am having this issue with hardware A4 and 1.21. I tried disabling DNS relay and the internet actually stopped working completely. Had to re-enable it to get back on. Has anyone else had this issue? My ISP is comcast.

You have to disable and re-enable your network connection, or just restart.

If you use a static IP, you'll have to manually set the DNS addresses displayed on the router's status page in your OS settings. If you just use DHCP, restart the connection like the guy above me said.

thanks guys. that did the trick. i will now add my name to the list of people waiting to see if this resolves the issue. confused as to why this is an issue on 1.21 firmware that's been around since November. Shouldn't 1.21 be rock solid?

You would think. Glad to hear it worked.

Are you seeing freezing or something else?  If you do a search for "DNS Slowdown", there was an issue with 1.21 that some people saw (including myself) where DNS resolution would start taking a really long time.  This was fixed in 1.22B05 and then subsequently released in 1.31+.  Disabling DNS relay was also a fix for that issue.

does DNS relay = Advanced DNS?

my router locks up randomly at least once a month, sometimes once every three days.

i know its the router b/c my surfing starts to simply not work, and when i try to go to 192.168.0.1 i can't.  power cycle the router and all is fixed.

any solutions?

No, DNS relay is on the network page.  You need to disable advanced DNS and securespot and then disable DNS relay.

I disabled DNS relay last night and have still experienced the issue with momentary lock ups. The connection is restored almost instantly, but still annoying nonetheless.

Question: I'm on hardware A4 with 1.21. Most people in this thread who have seen the issue and say disabling DNS relay solved it seem to have upgraded to 1.31 or 1.32. Should I try upgrading to 1.32 and then disabling DNS relay to see if it resolves the issue? I just bought this router yesterday, so I'm not really concerned about not being able to downgrade since I can just go return the thing.

I'm grateful for all input. Thanks.
