I currently have one router (AEBS) distributing service to over 5 machines at times. Considering buying a new router, and was wondering if this will improve the speed of the internet (also going to upgrade to 50 MB service). I wouldn't have it connected to a computer though, rather kept in my bedroom plugged in. Is this possible or does a router have to be connected to a computer at all times to distribute wifi signal? I understand setting it up initially with a computer, but does it need at all times to work?
