For the last couple of days I've been having major issues with my iMac. It's been detecting wireless networks from surrounding houses, and even detects the one in my house, yet it will not connect. Occasionally it does connect, but it doesn't seem to hold the connection for very long and there is no rhyme or reason to. I don't understand what's changed. I've not moved the modem/router and my iMac has not moved either. Any ideas? Do I have a problem with my AirPort ariel do you think? I'm at a loss on this.
