This would apply only to the UMN Secure network, correct? I think the UMN
and UMN Guest networks are unsecured.

Weird. I've got an Intel Centrino Advanced-N 6205. It works everywhere
else, but I'll try anything. I've saved instructions to disable 802.11n
locally and I'll try it tomorrow.

I've also got a Ralink 802.11g dongle of some sort I'll try out.

Thank you,
