So whenever I'm upstairs the wi-fi signal on my MBP is most of the time really choppy. It'll be really good one second and then it becomes crappy for a little bit, I won't lose it. But websites won't load. But when I come downstairs where the router is I have no problems at all. I checked on Kismac and when I'm upstairs the Max Signal is 26 and my signal jumps from 0 to 26 to 0 and so forth. And when I'm downstairs it sticks 46 out of 46(Max Signal). What could be causing the signal to go whack-o on me?
