[OLPC Networking] Wifi doesn't work well?

[Michael McGlothlin]

I have three APs and of them only one, the one that works the worst in 
general, works on a regular basis with the XO. All three work with my 
other laptops and have been tried in different locations with various 
settings and still only the dumpy one works. I can see lots of neighbors 
APs. Any idea why two of mine won't even show up in the AP browsing view 
99% of the time?
