I’m currently on the 76 download package. I have 4 extensions with star wiring but I still get full speeds of 76.
should I remove the extension wiring even if I’m getting full speeds? I thought having more extensions and star wiring deteriorates your speed but I’m still getting the full 76?
If it ain't broke and you're happy then leave well alone
where are the extensions connected if not master - maybe a junction box where incoming openreach wiring connects to internal wiring
if the incoming openreach connection goes first to your master and then to junction box which then feeds your extension wiring then that is not star wiring. star wiring happens when you connect your extensions before the master socket
Star wiring isn't considered good practice but at the end of the day it's the REN (Ringer Equivalence Number) that's important. This depends on the REN of each connected device, the number of devices connected, and, if the jobs been done completely wrong, the number of master sockets you have (there should only be one)
How is it possible to get an internet connection by connecting the extension sockets before the master socket? There’s no a and b terminal on the extension sockets??
From your post I assume your extensions are all connected after the incoming openreach cable is connected to terminals A&B in master socket - probably a connection from terminals 2&5 in master to one or more of your extensions this is not star wiring
