I have a Linksys BEFW11S4 BTW, and enabling encryption kills throughput
of this device. Their review of the Linksys while a bit dated catches
the serious performance hit WEP causes the Linksys. I have Optonline
and I loose a bit of speed on the wireless side. I top out a just under
3 megs but, my connection can hit upto 4.5 or 5 Megs on the wired side.
My Dell 1184 Router is much faster but, has a few issues with a few apps
and NAT that I was never able to get straightened out.
Obviously at this port you should be looking at 802.11G anyway.
