On my Mountain Lion iMac, I've realized that my wireless router disappears every time the channel is changed on it.  And for me to be able to find the router again, I have to reset the router and start the setup process all over.


Anyone have ideas on what I can do to resolve this issue?

iMac, Mac OS X (10.7.2), Boot Camp

    Over the past 3 months, I've tried all sorts of trouble-shooting steps I could find including the steps you've mentioned.


    The best success I've had so far is to prevent the router from switching between B/G/N, which keeps the connection live the longest.


    If I had to take a guess, the iMac is just terrible with wifi routers that allow multiple bands (B/G/N), and auto channel changing.


    By the way, I do not have this problem with my iPod Touch, iPad 1, iPad 2, and Windows laptop.  I don't seem to have a problem when using bootcamp Windows on the iMac either.

    Wireless routers vary in their compatibility with Apple devices. You could check the manufacturer's website for a firmware update. Sometimes that helps.
