We have three of them, but one is messing around. As soon as you download a bigger file, he loses connection. I can't ping the AP (from another PC connected via LAN), and the PC connected via Wi-Fi can't ping anything (ping 184.108.40.206).
So I started to check when this happens. I ping 500 times 220.127.116.11 and download a file. As soon is the download starts, 18.104.22.168 isn't reachable, and also the AP isn't. When the download aborts, everything works again.
Tested the same with the other APs, but they don't have this issue.
The APs are connected to the same switch. I also checked if there is an IP error, like another one is using the same IP address as the AP, but no, he is the only one. Interesting thing is, that the "broken" AP shows only 100 Mb Ethernet Connection, while the other are showing 1 Gb.
I don't know where to start looking. Maybe it's hardware failure?
