Has anyone had this issue I thought it was the router but I just got a new one and I am having the same issue. My macbook pro shows the network but is not connecting to it. It says connected but doesnt have any signal but then when I restart the computer the signal works fine? This just started happening it doesn't happen everytime but it has happend a few times recently and all the other computers I have work when this happens also. any feedback would be great.
