Two Wireless NICs - One stalls when other in use

OS: Vista

1) Two wireless network cards connected (both same make/model/driver
Belkin Wireless G+ MIMO USB Adapter F5D9050UK)

2) Each connected to different G wireless network

3) Routes added:
route -p add 216.196.109.131 mask 255.255.255.255 192.168.1.254
route -p add 216.196.109.144 mask 255.255.255.255 192.168.3.1

When download starts for 1st route at 20Mbits+, the second route (or
any traffic going thru 2nd NIC) becomes extremely laggy and totally
saturates the connections (high packetloss). When downloading stop at
1st NIC, 2nd NIC becomes responsive. And vice-versa when routes and
network cards switched around.

Why? Driver bug?

Doesn't happen when using a Wired NIC and Wireless NIC.

how close together are the antennas? are they on the same channel?? try
moving the antennas as far apart as possible, or orienting them at 90
degrees to each other and see if that helps. also put them on different
channels, there are some channel combos that are better than others for
preventing interference, i forget the best ones now but they are on the web
somewhere.

Thanks, moving the antennas seems to have fixed the problem, were just
30 cm apart before, now metre difference :)
