I'm posting this on behalf of my girlfriend. She has complained before at her apartment that often her MacBook has poor wireless performance. Slow speeds and dropped connections. I originally thought the issue was her ISP. Now, she is literately sitting on the couch next to me and is getting noticeably MUCH slower network speeds. We both tried loading Amazon.com at the same time, for example, my MacBook Pro loaded it instantly. Her's hung up on loading the page for awhile. The only difference between the two of us (other than she has a MB and I have a Pro) is that her's is not charging and is running on battery power. I remember reading awhile ago that MBs had poor wireless performance while running on battery power. Has this been resolved? Is there anything I should try? She has all the software updates (Running Leopard) and has all of the EXACT same network configurations as me. What should I do?
