Hi, I have had to set up my 841N as an AP, which worked previously, due to losing connection. I have followed many videos on TP-Link and youtube and thought I had cracked it but it will only work on wifi picking up my main router. I set up using a cat5 cable link but when i move to new position it does not work, so i have returned adjacent to the main router and it works without cat5 link on wireless. Can someone please help, its driving me insane now
