For the last 4 years I have used a Tp link AV500 powerline extender to extend the WIfi to my gite (guest house). Never a problem until last week when my guests were unable to connect to the internet. We tried reset, different sockets in the gite without success, but it works fine when in 5 metres of my Livebox (router). I have replaced the ethernet cable twixt livebox and adaptor.
Thinking that there was a problem with the extender I replaced it with a Tp-link AV600. Fired it up, same problem.works fine in my part of the house, nada in the gite. I've tried it in the gite with an ethernet cable attached to my laptop, nada.
The power LED, powerline Led and the WIFI clone buttons all show solid green in my house and the system works, despite the booklet saying that the powerline LEd is supposed to blink (doesn't say if it should be slow or fast) and the WIFI clone button is supposed to be blinking quickly.
Any Ideas on what the problem maybe and more importantly how to fix it wil be gratefully received.
