I actually had to just register this new forum account so that I could reply to this thread. I've had a TERRIBLE time with wireless on my new MBP Penryn @ home and at cafes where my old Vaio would pick up the signal ANYWHERE and was never let down. I'm pretty disappointed but I followed the advice to change the signal from 11->6 and that seemed to have fixed my situation at home at least. Not sure how the cafe situation will be but since I work from home, this is the most important. I'll report back if I run into problems again.
