Acer Travelmate laptop with built-in Intel 2200GB 802.11b/g wireless
network adaptor, XP Pro.
Netgear ME102 802.11b Access Point, plugged into network hub.
2 more desktop machines plugged into the hub, both Win 2k, it's a 100Mb
network.
The Access Point is approximately 3 inches away from the laptop.

That close may result in signal overloading in the radios.

I'm experiencing really bad network throughput at the laptop end, but
have discovered that copying a large file from the laptop to one of the
desktop machines is fast - the problem seems to be only when
transmitting data TO the laptop. I get all sorts of network errors,
including disconnections. Signal strength on the laptop is a full set
of green bars when I look at the connection status, "excellent" when I
hover over the tray icon.

I downloaded QCheck, installed it on a desktop machine and the laptop.
When I run a throughput test at the laptop, sending from the laptop to
a desktop machine with 100kb packet size, I get roughly 5 to 6 Mbps,
which as I understand is as good as you can expect from 802.11b.
However, when I run the test from a desktop machine to the laptop, I
get around 30 kbps. Yep, kilobytes per second. And that's when it
works, most of the time the test fails - it only works reliably when I
reduce the packet size down to, say 5kb, then it shows a throughput of
about 1 Mbps.

Anyone have any idea what could be causing this? I've tried all
possible channel settings, and combinations of all other settings I can
see.
