I am testing my MBP's wireless for the first time and i'm a little bit disappointed. I know that MBP in general are so-so with wireless, but it's sitting maybe 5 inches away from an airport express and the istat wireless widget reports 60% strength?!! Is that normal? I mean it seems to me that it should be 100% bearing in mind they are right next to each other. Also there are no wireless networks or anything else that might interfere (microwaves, etc.) in the vicinity. Thanks for the help.
