I have a very frustrating issue with my internet connection.
I have the black heavy duty BT cable coming into the house from the telephone pole. That is extended using proper heavy duty black extension cable (with the wire stiffeners in it) by about 3 meters to the BT master socket 5C on the wall.
The connection between the actual BT cable and the extension cable is via 2 gel crimps in a sealed junction box.
I had this setup running perfectly for about 3 weeks and was getting ping response times of about 10ms with no drops at all, then for no reason (nothing has changed) the internet connection started being really laggy, when I checked the ping response times they were dropping frequently and generally running at between 300 and 600ms.
What I have done to try and resolve this is change the gel crimps for better quality ones and replace the master socket with a new one. It hasn’t helped, if anything the connection is worse now.
I am guessing that the 2 cores in the BT cable are very sensitive and anything other than a perfect join is going to introduce noise to the line which will affect the connection. Am I right in my assumption? Is there anyway I can test the signal strength at the master socket to see if the problem is in the junction box or somehow where the 2 cores are crimped in the snap lock thing in the master socket. While I am writing this I have the constant ping test running and the response times have gone back to about 30ms with no drops but I know that next time I look at it the response times will be back to 600ms again. There just doesn’t seem to be any logic I can see to this.
I really hope someone out there can point me in the right direction to try and fix this as I don’t really want to spend £200 getting a BT engineer out to look at it…
