Wireless Access for DS Lite

Wait, your school wireless network has encryption? I can see why, but that's kinda pushing it. I've been in a local Community College as well as in a private University, and both places had networks without any restrictions. You could connect and it'd be fine, sure, they could monitor and find out what you're browsing, but you could easily connect. I'm sorry about your case. I think one of the easiest options would be to find another area that has a wireless router without WEP or WPA. Perhaps leech off another person's internet somewhere in the dorms?

Edit ; Personally, I wouldn't spend anywhere near 40-180 dollars to buy a wireless router just for a DS, but that's just me. Unless you really need it just so you could connect to the internet to do homework, research, etc.
