I had to re sync them in the same double socket, never had to do it before but it worked. Plugged back into an extension lead, running through an 8 port Ethernet switch and running a smart telly, Xbox, wii, sky and blu ray player. No slowness in connection and I may even say its running better than when we had wireless. If you go onto the to-link website you can claim a free plug adapter at the mo. Tp-link not to-link lol P.s. I don't know what you have to do to get the free one, I just saw it when I went on there website.
