I get free wieless sinalin my apartment but the sinal ii very weak. I was wondeing if I can use a wireless router as a repeater or access point and increase the signal. Can I use the wireless router I have as a wireless access pointwithout hadwiring it with another router or modem with internet signal? Is it possible to use a wireless router as a wieless accesspoint, without hadwiing it with another route o modem? If possible how do I do that?
