I have been plagued with this issue on DD WRT firmware for over 3 years now and although I've been hunting down a solution i haven't found one that knocks the problem on the head.
After being connected to the router for a prolonged period of time, sometimes a couple minutes, sometimes hours, I will lose connectivity to both the internet and the router even though Windows still reports that i am connected to the router.
I get the yellow triangle over the wireless strength icon in the taskbar and hovering over it states "No internet access" or "No network access". Checking the connection details in windows shows i still have an IP address assigned and that i am still connected to router.
I have tried various techniques including adjusting power saving settings for the wireless card and disabling wireless N on both the router and the wireless card. Only a disconnect/connect cycle resolves the issue until it happens again.
My other two laptops connect with Broadcom and Atheros Wireless cards and have no problems. They can be left connected for days at a time without losing connection.
When i use these other laptops to login to the router to see whats happening when the 4965 disconnects, the 4965AGN is not on my list of connected devices even though windows still thinks it is connected. It seems that the router is disassociating with the wireless card (Why, i have no idea). Assigning a static IP address or raising the client lease time to 99999 minutes does not make any difference.
This does not happen with the original Netgear firmware or with any other router.
I have been hoping that it was a bug with DD WRT that would be ironed out but 3 years down the line it's still an issue. I would like to think that its a way DD WRT handles this chipset or that its a way the Intel chipset interacts with DD WRT and that DD WRT could be issued with a fix as it is the only common factor in every set up i have tried and I'm convinced its DD WRT.
But i am no software engineer and that's why I'm here.
I've read the Peacock thread and i do the 30/30/30 hard reset when required. I've tried the firmwares recommended for my router chipset and I've regularly searched for solutions to no avail.
If I'm not having any success after a good stress test I'll bump the thread and similarly if I'm successful I'll do the same so the answer can be Googled by anyone who needs it.

also alot of rx/tx errors are due to noise around you, did you do a site survey and using a good channel with no neighbor noise interference? is there alot of cell phone, microwave, Radio interferences from neighboring Wi-Fi etc. _________________ Wireless N Config | Linking Routers | DD-WRT Wiki | DD-WRT Builds | Peacock - Broadcom FAQ
Out in the country I'm the only AP for a couple miles and I've taken care to keep the unit away from other appliances.
Turning down the power to 35mW has already increased the signal quality from both my phone and my laptop over 10%. I'm getting signal quality of about 60-70% at a 6 foot range with the noise varying between -81 and -90.
Had over 28 TX errors in the last 45 mins though. They happen about 9/10 at a time when a device connects but once connected it seems to stop.
WRT320N is a good price and looks not too bad, however the process to put DD WRT on for the first time looks a little risky and seems plagued with issues.
