Use Existing Cabling to Extend your Home WiFi Network with AuraGrid

Eliminate any dead spots in your home's wifi network with this product that harnesses the already-in-place coax cable running through your home. From Smarthome:

Use one of the included extension units to connect your router to the AuraGrid, and wire the additional extensions into the cable entry point of the rooms to be connected. Each comes with an antenna: Rooms that are equipped with an AuraGrid antenna will enjoy maximum wireless signal strength as well as data throughput without interrupting cable TV/Internet services.

Great idea.
