Query: Good alternative to WiFi

I use this in a place where I can't run an ethernet cable and have a weak WiFi signal because of multiple walls between my router and PC. Installation of the Powerline Ethernet Adapter was a snap - just plug one into the router and a plug, and the other (which you have to buy separately - so you need 2) into a plug and your PC ethernet port, and you are good to go. Couldn't have been easier. Maximum throughput in my home (built ~1985) was about 300 kbps.
