Good morning,

I'm writting here today because I can not connect to Internet with the TL-WPA4220 product.

I am trying to connect with wifi but my devices like my computer or my phone can't. The device has been working perfectly wince yesterday when I was playing a video game my ping went to 500 and my connection crashed and since now i still can't have it back.

My devices still detect the wifi extender as "TP-LINK_D69E26" and the signal is still pretty high but they can not connect to Internet. But when i i'm trying to fix the Internet problem it says something like "Wifi has not a valid IP configuration" with a red cross on its right side. I have already tried to unplug the router, to enable and disable my wifi card without sucess.

I dont know what esle can i do and I would like to be helped to fix that problem

Thank you for your help!

(PS:Excuse my english)
