I have the TL-WR841HP router several months ago, about a month ago I started experiencing problems.The same I use it as AP, I have connected my PC by LAN. One day I connected with my phone like any day and did not surf, I noticed that I was giving an IP in the factory range.I configured it at the time 192.168.1.X, but connected from my cell was giving me the IP 192.168.0.X as if it was of factory, BUT IF I WORKED MY PC BY LAN and it gave me an IP in the rank 1 .
I reset it and reconfigure it, and when I try to connect to the wifi it tells me the wrong password. It does not authenticate well, try several times and the fourth time it works.

Does anybody know what is it due to.I have the latest firmware version
