David,

Thanks for a thoughtful and thorough response. In point of fact, I am already operating on Chanel 6, having avoided the Channel 11 default as you referred to. But maybe there is an even better channel assignment that might work better.

1.  It's not that they work at the same frequency, but on the same set of 
channels (11 of them in North America).  You probably never set the channel 
but just left it at the default setting, right?  Well, your neighbors have 
probably done the same thing!  So you may get back to something like the old 
performance by changing the router to a non-default channel.  (You could download NetStumbler to your daughter's PC and run it to see what other wireless networks are in range, and what channels they're on.
  Note that for full-speed operation, both b and g will spread out to two 
additional channels on either side.  So if there are no other nearby 
networks, it's common to put them on channels 1, 6, and 11 to avoid 
interference that would limit speed.  You might not get that lucky, but if 
you find neighbors on channels 3 and 6, putting yours on 4 or 5 will not do as well as 11....
