Moving furniture around I unplugged the AE. Replugged and no wireless for iMac, ATV2, iPad and a laptop. I have a new Lenovo laptop and plugged ethernet directly, then wireless started to work. The only difference now is I had a PC plugged in via ethernet from the AE. How do I get it to work again or just start over. Tough when you have no cable and kids asking to watch tv (i.e. ATV2). Thanks all.
