The installation was completed today.
A nice guy from Kelly arrived, put a new faceplate on the socket, with 2 ports, he said that there is no need for micro-filters and that the same wires are used, connected the modem, done the job at the cabinet, connected the router with the ethernet cable I provided and that was it.
He didn't have like one of those tools that measure signal levels, attenuation, noise etc.
Did a check on a mobile phone and told me that my line will support 10Mb upload out of the 20 promised because of the exchange. My postcode is SM1.
The results are:
Wired computer shows on Xilo server on speedtest.net 37Mb download/ 9Mb upload.
Wireless connected laptop, on the same server, 32Mb down/ 9Mb up.
I am happy for the moment, I hope to have no problems at all
