So if you see this weird WiFi problem, disable your wireless security settings, save, then setup your wireless security again.
Probably, somehow the wifi security settings in my NVRAM got corrupted.
I too was having a wifi problem, without security everything was working, with security (regardless of type) I saw 0 ok and 1000's of errors.
For me disabling and re-enabling security was not enough. DD-WRT kept remembering the WPA key.
I managed to fix this issue by using the following commands:
nvram set wl1_wpa_psk
nvram commit
The first command is usually followed by a key, but by omitting it I cleared it from the NVRAM, the second command writes the changes to the NVRAM.
Since these two commands my WRT610n is finally transmitting on the second radio (A/N on 5 Ghz).
If anyone else is having a problem with the FIRST wifi radio, please use nvram set wl0_wpa_psk.
Thanks this worked for me too. Glad you included the part about the first radio.

I realize this thread is two years old, but
a) google brings it up for "dd-wrt wifi stops working" searches.
b) The solution of writing the nvram directly worked for me too.
Here are the details:
I am running "DD-WRT v24-sp2 (08/07/10) voip - build 14896" on a WRT54GL and have for years. I was a tomato fan until they stopped fixing bugs and now consider dd-wrt my goto firmware. When the WRT54GL dies, my next upgrade will be a dd-wrt ready router.
I thought it had died last night as the wifi just stopped working and like others, the symptoms were a TX with %100 errors and disabling security brought WiFi right back up.
Here is what eventually fixed it for me:
- Cleared the UPnP list
- Reset the WPA2 password to something else and then back using nvram commands (under "Administration" -> "Commands").
In my case, the setting I had to clear was "w10_wpa_psk". It took a few times and I ended up changing the SSID a few times until I could set it back. I bit afraid to reset the router, but everything is working.
Router randomly stopped working after about 4 years of rock solid service. I guess the power outage we had screwed something up, wasn't even in the broadcast list and there were several hundred-thousand TX errors. I didn't even need to go as far as the command console, just change the SSID/Encryption/Password, applied, and swapped it all back. Worked immediately.
(me again) I reset my router today and was dismayed to find the wireless not working/missing again. I vaguely remembered I had this problem before and managed to find this thread. I did the same as t3ch above:
changed the encryption/password
hit apply
changed it all back
hit apply
and it works again. I could tell it was working because the "Status" -> "Wireless" errors had stopped counting up. Yah!
I'm documenting it again because it will have to be fixed again in the future. The good news is that the router is on a UPS and as long as I don't manually reset it, it should be good.
I will be keeping an eye out for a new router - thinking a Buffalo N300 DD-WRT
I’ve also hit this problem several times already and searched for solutions. I played with nvram unset and managed to solve it after some hours but it always come back after some time. Today it happened again, I noticed an interesting thing, when I queried nvram it reported this:
size: 32776 bytes (-8 left)
I started to think that my nvram is full, then I was thinking and suspected the traffic statistics on Status / WAN page. I had data for years back, I’ve even read somewhere that it stores the data in NVRAM. I deleted these statistics and now the nvram status is:
size: 20891 bytes (11877 left)
My wifi started to work immediately.
Yes. Please read the forum announcements carefully. _________________ SIG:

I haven't been active in the forum for years.....I know nothing. Don't listen to me.
Just in case someone else has this issue with 0 OK 8,000 Errors TX, I figured out how to fix my issue. I didn't upgrade my build or anything, same build. I restored my backup, and of course the problem came back. I then disabled the WiFi security, I'm assuming this wiped the settings from NVRAM. I then re-enabled wifi security and set it up to be what it was before, same password and everything. It's working fine now, no problems, just as good as it was before.
So if you see this weird WiFi problem, disable your wireless security settings, save, then setup your wireless security again.

Ok, thanks for the solution since I had the same problem and I solved it by following the same steps.
