Homeplugs may well do the job, but they are hated by anyone trying to use the SW bands due to the hash they radiate. Hardwire whenever possible please, Homeplugs last resort.Homeplug adaptors use your existing house wiring to send broadband signal around the home. You plug one in at your router & join them with an adsl cable. You can plug the other one in anywhere you have a 3 pin socket and you have an instant broadband connection socket. You even get them with built in wifi giving you a wireless access point.
.....then swre at the sucker and it started working.
Hardwire whenever possible please
