i have an xbox and want to connect it to the internet without forking over 100 dollars for the adapter(the access point is upstairs, system downstairs. why not put it upstairs? hd tv downstairs ). i have an extra wireless router(lan parties XD) and would like to turn it into an access point that i can run an ethernet cable between and then have the router get/send info to the router upstairs. how would i do this? is it possible?
