Buffalo AP randomly becomes unresponsive
I have eight Buffalo WHR-HP-G54 units flashed with DD-WRT (v24-sp2 std) and three out of the eight will randomly stop responding to network traffic. When they become unresponsive I am unable to ping or connect to the web gui. Clients can see the AP but get no IP when connecting. If a client is connected when the AP becomes unresponsive the connection drops and displays the x on the connection status (Windows 7). In my troubleshooting I thought maybe the problem was coming from multiple connects/disconnects over the course of the week so I created a cron to reboot each AP every morning before any clients attempt to connect but that didn't seem to help. Unplugging the network cable to the AP and reconnecting it will bring connectivity back and it will work until it randomly quits again. Same goes for unplugging the power and rebooting the AP. All eight AP's were flashed at the same time with the same firmware and have been in place for over two years before this problem arose. I have replaced cables and changed ports to where the AP makes the connection back to the core router/switch but that has not changed anything. I thought I would ask around before I reflashed the AP's or replaced them. I know it's not impossible that three units could be bad, but I find it odd that they all lasted the same amount of time before failing so I have to believe it is software or a load issue.
