Many folks at home are unaware of the technology where, with inexpensive devices, you can create a wired computer network within the confines of your home by using your existing electrical wiring. Setting this up is actually quite simple (plug and play) and be done by using the devices manufactured by TP-Link. Typically one device is plugged into an electrical outlet at your router then plugged (via ethernet cable) to your router. The other device(s) are then plugged into outlets in your home, paired with the main one at the router, then plugged into the computer or components using an ethernet cable.
Wired networking will give you better security, speed, and performance; which, are the main reasons to give this a try. It is one of those networking options that people do not think about and/or are totally unaware of. This eliminates having to run networking cable all through your house and is a good option if your wireless connectivity is poor in certain areas.
