    I have a fairly old macbook, 2007, but am running Snow Leopard. Recently it has taken to randomly disconnecting from our house's WiFi network. The other computers in the house connect fine, but my MacBook sometime just disconnects and it shows an exclamation point over the WiFi bars in the top right corner. It then asks for the password, even though I have it set to connect automatically, then it never reconnects. If I shut down the computer for a bit, it will connect and work for awhile. Anyone have any idea what's up? Thanks in advance.

    Same for my MPB 2007 (but I don't have Windows on it so I can't say for Windows)

    Could be a channel conflict with cordless phones or neighbouring access points, worth a shot to see if this fixes the problem.

    I had this problem and changing the channel solved the problem. It was odd, there are two old white MacBooks in my house and only mine was playing up.

    What did you change the channel to? I changed mine to wireless G only and it didn't help. I don't have any cordless phones in my house.

    Vista, how do you change the channel on a router?

    Switching to wireless g isn't the same as changing the channel.

    Changing channels on a router differs by brand, you should download the user manual specific to your router model.

    You have to navigate to your routers config page using your web browser the address is usually something like http://192.168.0.1 for home networks. Once logged in you hav to find the wireless settings option. You can usually find the channel option in here.

    Wifi disconnect issue is finally gone!

    I tried _EVERYTHING_
    even taking my imac 3 times to the Apple Store (not easy, it's heavy!)
    And of course those dorks couldn't see _anything_ wrong because their WIFI inside the apple store has no security and the problem with the wifi disconnect is when there is security enabled (in my experience).

    I just updated to Mountain Lion and the problem is gone! So it was definitely a bug in Lion.
