802.11a WAP channel question

I've noticed that if I pick a high channel (60 or above) I have a
plethora of issues regarding connectivity. Very poor connection,
might be able to browse my local home network and connect to my
server's shares, but can't get on the web... Then the connection gets
lost, and the access point doesn't even show up anymore in a list of
wireless networks. The 802.11b part of it does (it's dual band) but
the A part doesn't. As soon as I drop the channel to a lower number,
say low 50's or high 40's, it works just flawlessly. So it's
obviously not a problem, because I can get it to work.

I'm just curious about what the difference is between channels? Is it
just a slightly higher MHz signal or something? Since the card I use
doesn't have it's own client utility that I've found yet (Dell
Truemobile 1400 A/B/G Mini-PCI card) I don't have a way to force it to
use a certain channel on the client side.

Again, it works, I'm just looking for some knowledge about the
particulars of this aspect of wireless networking.

Thanks for any info.
