    Hey there. Since I've been running leopard, my 2.16 CD Macbook Pro's internet connection comes to almost a standstill when my power cord is plugged in to the computer. About a minute after I disconnect it, everything's back to normal. I've searched for others with a similar problem, but I haven't had much luck. Any advice? Thanks

    Sounds pretty bizarre. The only thing I can think of is check the Energy Saver pane in System Preferences and make sure that the settings aren't set to reduced performance for AC power.

    Same Here

    I have been having close to the same problem with my 15" Macbook.
    I bought it in september 07 but recently have not been able to get ANY wireless signal when the power cord is plugged in. If I have a low battery then I usually have to: load a page->plug in to keep it alive->read what I want->then unplug after clicking a link to load again... (kinda sucks)
    This could be because I am using someone else's wireless in my apartment complex (not always the best signal), but it is strong enough to work fairly quickly when I have it unplugged. I will see what happens when I go back to my house for thanksgiving (I am in college for now) so I can use the wireless network that I set up there.

    Again, this is frustrating because there seems to be very few people with this problem... Any help would be awesome

    Ok, so I am at home, and the internet works fine right now even though it is plugged in... so I have to assume that some combination of unreliable internet signal, interference of the electrical current itself, or possibly the magnet on the cord (yes, I know it is supposed to be insulated inside the case)causes some glitch... at least in my situation...
