I replaced my cnet el cheapo router with a Linksys WRH54G. World's apart in terms of signal strength. Now the whole house (1st & 2nd floor) is a hotspot. Abot din yung signal sa garage and front yard.
I upgraded my old TPLINK G router to TPLINK N enabled router. Faster data send/receive and wider range throughout my home. I can barely find a dead spot with this new router.
