Is there anything that I can buy to improve the signal of my wireless network?

Question

Basically I have wireless internet at my house but its a big place and the signal is very weak or nonexistant in certain rooms. Is there something i can purchase to boost the wireless signal that I dont have to plug in an ethernet cable? My wireless router has the ethernet cable connected to it and i really just want something that can take that signal and boost it. thanks!

Yes, you buy a Range Booster and install it in line with your router.  You can buy one at any large computer store.
