Powerline networking starter kit on the cheap
I know from experience that there some parts of some homes that simply can't get a decent Wi-Fi connection. If your home doesn't have Ethernet cables in the wall powerline networking may be your only option. D-Link has announced a new powerline networking kit that's impressively low priced at $59.99.
The adapter kit is called the DHP-308AV and includes a pair of small adapters that support 128 bit AES encryption for security. The adapters use your existing electrical wires in the home for connectivity and leave the second plug in your outlet uncovered.
