I've had a WZR-HP-G300NH (v1) router for a while now, and I'm finally getting around to writing about some frustrating wireless behavior that has been occurring for as long as I've owned the device. The basic symptom is that periodically all wireless connections fail (sometimes a couple of times a day, sometimes days apart). The SSID still appears, but connected devices are no longer able to send packets -- pings fail, can't connect to the admin page, etc. Sometimes the device recovers after a long while. Sometimes I have to walk across the house and power-cycle it.
The same basic symptoms occur whether I'm running builds acquired directly from the dd-wrt website (I've cycled through many over the course of two years -- 17461, 19519, 21676, 21286) or the latest officially blessed builds from Buffalo (19484 what I'm currently running now).
In the failure state (usually after a while), sometimes the pings start to get through and look like this:
Request timeout for icmp_seq 40
Request timeout for icmp_seq 41
64 bytes from 192.168.1.1: icmp_seq=42 ttl=64 time=599.500 ms
64 bytes from 192.168.1.1: icmp_seq=43 ttl=64 time=138.058 ms
64 bytes from 192.168.1.1: icmp_seq=44 ttl=64 time=779.801 ms
Request timeout for icmp_seq 45
Request timeout for icmp_seq 46
I've tried looking at the syslog (setup via instructions here:
http://www.dd-wrt.com/wiki/index.php/Logging_with_DD-WRT), but nothing appears unusual.
I've tried several different suggestions found on the forums without any luck:

Some details about my setup:device: WZR-HP-G300NH (v1)
build: DD-WRT v24SP2-MULTI (07/15/12) std - build 19484
Wireless-N only, channel 6 (fixed)
No WEP/Security Password (I use MAC filtering to only permit certain devices to connect)
No bitorrent running
No optware
No USB drive attached
Wirelessly connected devices include the usual smattering of mobile devices, iPads, a wireless bridge (that I've ruled out of being a problem by disconnecting it for a few days)
In my frustration, I even purchased a new WHR-300HP and had almost exactly the same behavior. Given that the same behavior occurs on both devices, I'm inclined to think there's a serious software issue here.
I'd appreciate any guidance from Buffalo support or other forum members about further options for debugging and/or isolating this behavior.
Thanks!
