TP-LINK AV500- Connected, but no internet/failed to obtain ip adress
I have my old tp link av 500.
About 2 months ago it started to disconnect from my wifi.
Now when i'm trying to pair it sometimes it is connected, but no internet/failed to obtain ip adress.
Cable is good, i can connect to my network from lan or the router wifi, but tp link is not working. I can't login to it's site to check the ip and mac and netmask.
Router restarting does nothing, it works for a while, but slower than normal and disconnects.
What can I do?
