i own an asus m6bne. i recently got back from a month long vacation and now i constantly have to keep turning on and off my wireless card because the internet just stops working. once i turn it back on, it works fine. i get a message that says "limited or no connectivity". what could the problem be? im thinking it cant be my router because the other 3 computers in my household work fine. it was working fine before i left. thanks.
