Just bought a new house and had Verizon FiOS (TV, phone, internet)
installed. Internet access is 5 down, 2 up.

My wife's computer's internet connection works fine; it's hooked up to
the Actiontec MI424WR router by ethernet cable.

My machine (Microsoft XP SP2) is in the basement. I connect via a
Linksys WMP54G v4.

Verizon speedtest says I'm getting about 1.4 up (fine with me), but
really crappy download speeds---on the order of 100 Kb/s.

What's the likeliest cause of this?

I dusted off a labtop this morning and tried connecting with that. It
was even worse; couldn't download enough to get the speed test working
before I had to leave for work this morning. (That card is 802.11b
only, not g.)

I also don't see any other networks in the Linksys wireless monitor
interface.
