I have cremoved the front plate from the master socket and connected to the test socket and here are the results (I had to use my fathers PC on wirelss as the cable isnt long enough for my pc)
Managed to run the test on my too (cable was long enough)
Here are the speedtest results with router plugged into test socket:
So I need to leave the router plugged into the test socket for the next 3 days?!
Again for my pc (cabled not wireless)
Do I need to leave the router plugged into the test socket for the next 3 days to get the speed back up to 8-9mb?!
I would leave in the test socket for the 3+ days and maybe think of improving your sockets. with your attenuation I would expect a connection speed of about 11/12mb on a good connection
