So I recently got the ASUS N66U and it has been working fine for the last 3-4 days. But yesterday I had a problem where all my mobile devices were connected but would not be able to load anything that needs internet. So this morning I tried to use my laptop (which is connected through a LAN cable) and it worked fine. Then I disconnected the LAN and tried it over wifi, still worked fine. Then I tried my mobile device again and everything seemed to work again. But whenever I reconnect my laptop to the LAN cable, wifi stops working. I could really use some help here.

 
Solution
I would start by resetting the router and then updating the firmware from an Ethernet connected computer using the latest firmware version from ASUS SUPPORT since there have been a number of firmware updates this year.
