Home networking can be a tricky thing especially if you have an older house without the proper cabling. If you're not too keen on wireless technology and need to access the internet from rooms where the router or cable modem might not reach, TigerDirect.ca has a good deal on a powerline adapter kit that should make things much easier. Right now, you can pick up the TRENDnet TPL-303E2K 200Mbps Powerline AV Adapter Kit for $49.97 after using the coupon code RBQ59626 at the checkout. Even at a regular price of $90, this would still be a decent buy as these kits usually only include one adapter and can jump in price pretty quickly.
These kits are easy to set up as all you have to do is connect one end to an AV line and the router or cable modem and the other to an AV line in the room where you need access to the internet. Installation is the definition of plug-and-play and you should be able to get things up and running in no time. We're not sure if this kit includes Ethernet cables so you'll need to make sure you pick some up if they don't.
The coupon expires on April 29, so you'll want to order online or head to a TigerDirect before then.
