I live in a house built in 1949 which means plaster walls and lead paint. I currently have a wireless router set up in the front of the house near one computer that needs internet access. My PC is in the back of the house where I get absolutely no signal strength. Will a booster get the signal to the back of the house? What should I look for if you think one will solve the problem? I guess I could always take it back for a refund if it doesn't work. Also, Ethernet wiring is not a solution. Again the thick walls and distance from front to back of the house is just to much of a hassle than just not getting service at all. I actually have some kind of jack that plugs from the wireless router into the electrical wiring and then I have a jack in the back room coming out of the wall and plugged into my Ethernet jack. This gives me service occasionally but it fluctuates in and out so these devices are not a solution. Thank you very much.
