I had bought 4 of these routers from NewEgg, with great expectations. I had been using Buffalo Routers since the days of the WHR-G125, especially the WHR-HP-G54, both of which use the Broadcom chipset and DD-WRT from around the same time, in probably every type of configuration possible, AP Only, WDS, Client Mode, Client Bridge, Wireless Bridge, etc. Swapping over to the WZR-HP-G300NH I expected to work just as well as what I had been used to before but there has been nothing but issues. I have tried the Stock Firmware from Buffalo (1.76), the Buffalo Branded DD-WRT (V24-SP2 build 14998), the latest stable versions of DD-WRT (14896), even the latest beta versions (15778) but simply could not get a stable AP and/or Client Bridge working. There are a lot of posts about the Wireless N (madWiFi) driver, the Atheros chipset, etc. simply not being able to cut it, one post recommend using Wireless G instead, another post said to try the Broadcom chipsets, another said to try OpenWRT, etc. None provided any solutions to the issue. I now have two WZR-HP-G300NH's which are running the latest Buffalo DD-WRT which I can connect to, get an IP address but cannot do anything else, PING fails, etc. I have tried Buffalo's CD Image to revert to the stock firmware but simply get an Requires Administration Permissions error, irrespective if I actually run it as Admin or set the Compatibility Mode to Run as Admin. The ONLY silver lining in all of this is that I tried this first in house before doing anything with any client's otherwise this would have been a huge embrassement to my 30+ years of a Systems and Development guru. I would hate to know how many hours I have spent trying to figure out if there was any interference, incomplete router flashing, invalid configuration, etc. but the simply state is that it runs for a while and then dies, a simple reboot get it working again, which leads me to that firmware being the issue. I am now trying other implementations of WRT, like OpenWRT (which is don't like as much as DD-WRT) but looks like I either throw away all my Buffalo Wireless N routers, especially those with the Atheros chipsets (which I believe to be the better chipset), I have 4 WZR-HP-G300NH's (Atheros ar9132), 2 WHR-HP-G300N's (Atheros ar7240) and a WHR-HP-GN (Atheros ar7240). AARRGGHH!!
