My macbook pro cannot connect to my express. The green light is on but I have no signal. My macbook can pick up the network but when I enter my password it wont let me hit submit. It doesn't find the base station in any of the setup utilities scans. I've restarted my router and everything numerous times, unplugged it all and what not and still nothing. My wifi enabled phone doesn't even get a signal from the network. I updated to the latest firmware, it worked for a few days now it isnt again. Whats the deal?!? Thanks.
