I lost my wifi connection without warning getting the "no connections available" message and not being able to solve it I plugged in a second laptop with same resuluts. I then plugged in the ethernet direct from yhe Wimax modem and both laptops work fine. I bought a new router but with no improvement. So 2 laptops and 2 separate routers produce the same result...nothing on wifi, perfect on ethernet. WHY? Reward to charity offered for anyone who can help get me back on wifi.
