Heartbeat failure and connection issue
I noticed one of my 225 EAPs had no clients, every so often i would see heartbeat failures but it would recover yet no clients would connect. I ended up rebooting the EAP, which then fixed the heartbeat issue and clients are then able to connect.
This was okay for a day or so but then I noticed even with clients connected the pings were extremely high such as 3000 with a ton of drops, I then went ahead and unplugged the EAP and plugged it back in, it is now okay and pings have returned to normal.
I've had this happen a few times, that after a few month I need to physically unplug the EAP to get it working correctly, a simple reboot does not work.
Do i have a defective unit?
