|gambit, the home plugs do not boost the wireless signal of your router. All they do is convert a wired network connecting to a signal that travels over the power lines in your house and then convert them back at the other end.|
They work great if you can't run a cable and you have problems with wireless range, but their not foolproof. Some problems can be is if one end is an addition to the house that was built on later than where the other end is, especially if you have separate breaker boxes. Another can be, if I remember, sometimes surge suppressors or battery backups can degrade the signal if the adapter is plugged into one. Try plugging the adapter straight into the wall if it is plugged into a power strip.
Assume that I already did an Internet search.
