It looks like the network is 802.11n (it tells me I'm connected at 130  
Mbps), and in my (granted, limited) experience with 802.11n gear is  
that unlike 802.11g, it has no compunction about about stepping on  
802.11b—hard.

Perhaps things would work better for last century's wifi cards if 2.4  
GHz stuff is set to 802.11g. Or maybe not...
