If you hate that AirWes login screen as much as I do, configure your computer to use AirWes-wpa, a hidden yet ubiquitous secure 802.11 network. You type your login credentials into your wireless network configuration preferences, your computer automatically connects and you need never see that stupid fucking impediment again. Instructions from ITS for Windows & Mac are here -> http://www.wesleyan.edu/its/wireless/WirelessSecurity.html
Ubuntu/Linux users essentially follow the Windows instructions regarding authentication scheme.
EDIT: Vista users, you might try the instructions (under the heading Manual Configuration) on this page (BE SURE TO USE PROTECTED EAP/ PEAP AUTHENTICATION) Let us know how that works out. Somebody from ITS answer the question about ethernet cabling… VPN software make no sense (since you’re already on the network you would be accessing) and would be slow.
