I just got a new modem, it's wireless but the wireless is horrible on it, so it's hooked up to my airport express. Ever since I got it, the iPad and iPhone have gone on the Internet with no probem, but my MBP constantly struggles. It will work for 2 minutes, then not for 5 minutes. Then work for 6 minutes and not for 10 minutes. It's made the Internet on my MBP completely unusable. Does anyone have any tips for how to solve this? MBP is mid 2009 model, all OS's are the latest. iPhone 4 and iPad 1. AE is fairly new and the lit stays solid green. Thanks .
