I actually broke down and drilled a hole through two walls to get a wired connection for the xbox as I believe that is best(just didn't want to have to deal with drilling holes but oh well)...but I'm going to test the router method soon, as my brother is in possesion of the other router - going to get the router from him next time I see him...
but what is interesting is this website
http://www.sveasoft.com/turns out that they got possesion of the source code for a linksys router due to some open source thing(somehting like the linksys router is run on linux code, and since linux is opensource linksys had to release the code)...but they made their own firmware which "is a replacement firmware upgrade for Linksys WRT54G, WRT54GL, and WRT54GS, the Buffalotech WBR2-G54, and the Belkin F5D7230-4 wireless routers. Our firmware adds dozens of sophisticated features to these sub-$100 routers turning them into the equivalent of products costing hundreds or thousands of dollars. Support for several more router models from Buffalotech, Belkin, ASUS and other manufacturers is under development."
I have that belkin router, so once I get that back I'm going to test that firmware out...also got an old linksys one that I'm going to test out with the other method too...interesting site there though if you have that linksys router
