As of next February it won't matter any more. At least not for analog
interference. Can't say whether the interference with be a problem with HD
channels or not. Eventually many of the current HD channels using UHF may
move 'back' to VHF after the transition.

Meanwhile, it sounds like the Buffalo unit isn't shielded properly. Could
be any number of things being defective. Could be the power supply, the
router itself, the TV or the way it's connected to your antenna/cable.
Simplest answer might be to switch the Buffalo WiFi setup to a different
WiFi channel. See if that helps, if so you're done. If not then it's
likely something defective. If it's new and you can return it easily then
consider that option.

Actually, I was completely wrong. I tested it again, and
the noise occurs even when the laptop is powered down, and
the download is going to the desktop computer via ethernet.
I still need to try it with the router completely out of the
picture.

My modem says the down frequency from Cox Cable is 663 MHz,
and the up frequency is 29 MHz. Channel 6 is 82-88 Mhz.
Not sure where the problem would be.

Well I'm on Cox Cable, and they say he whole analog lineup
is gonna stay where it is after the transition. So channel
6, on the cable at least, will still be at 82-88 MHz, as
well as at other frequencies in hi-def for those with cable
boxes.

So disconnect the router from cable and talk ethernet from desktop
to wireless on laptop. Now what interference? Then repeat the same
experiment - communicate locally with the router connected to cable.

Looking for a device that has an IF or harmonic of 88 Mhz.

"My modem says the down frequency from Cox Cable is 663 MHz,
and the up frequency is 29 MHz. Channel 6 is 82-88 Mhz."

Upstream modem @ 29Mhz has a 3rd harmonic of 87mhz.
