Can a wireless access point act as a range extender? Say I have a wireless G router and a wireless G access point. Can I just plug the wireless access point into the middle of my house and use it as a wireless repeater? My router is on the 3rd floor and my computer is on the first and I do not get the greatest signal. Can I plug the access point into the wall on the second floor and boost the signal? How would I have to set that u p? TIA
