Hi there,

first of all, thanks in advance for the answers...so, here i go with my problem. I own a AP ASUS WL-550ge connected to a router to get internet. The point is that everything was working fine, but since few days ago, when i try to connect, it says i only have local area network, and get no internet. however, if i connect my laptop straight to the router by cable works perfectly.

The setup of both AP and router are the followings. Any idea of what I should do? it is driving me crazy! PS: sorry for my english...
