Both pairs are a part of the same cable. I will be really impressed to see different stats on individual pairs within the same ethernet cable, don't think it will be different here as well. The proof here is that at the physics level lines are identical - stats proves it so I will not accept an explanation that "all lines are different", that is a pure simplification. Like I said I accept that hardware could be different, but it will not justify 25% performance difference. And since it is moderated by BT, that's really great, maybe they will have a look at it at some point, and consider changing the culture of "do whatever it takes not to let customers pass the first line of defence". Nothing personal, they are great script readers.
Hi @Kamehameha and thanks for posting.
Can you post your helpdesk details? You'll find them in Troubleshooting/Helpdesk on the web interface at http://192.168.1.254 or http://bthomehub.home or if you don't have those details can you run a speed test including the further diagnostics and post the results.
Thanks for looking into it. I don't have a BT Homehub, I use Vigor 2860ac which is alo on offer from BT for business customers. I have performed the test, and results are attached. Also I am attaching the router stats (from console, below; connection time - 00:41:20. SNR is 4db, but usually it drops to 2db, I think it didn't like me running the test and disconnecting several times). Test environment: Router plugged into BT MK3 2014 socket, no additional wirng/lines/etc. WAN2 interface (fed from a aparallel Sky line) disconnected; all etherenet connections unplugged. Wireless deactivated. Laptop directly connected via ethernet to the router. MacOS X; created a clean configuration. Browser: Chrome.
Also, just in case attaching stats for the parallel (sky) line.
