You may be checking at the wrong place there. The external socket at the master should be about the same, but the internal Test socket may be better.
Yeah, I was referring to the internal test socket, the SNR is a little higher (0.5 -1db) when plugged in there when compared to the extension I wired up, but the speed still isn't notably higher as I recall. Even though I say it myself, I'm quite pleased with the wiring work I did as the SN margin has shot up by nearly 6db and the connection is so much more stable than before.
I suspect its the downstream SNR thats causing the loss of the last little bit of speed.
That's what I presumed I could ask my ISP to do - change the SN margin to a lower value and get some increase in sync speed. Virgin said it couldn't be done and my line was maxed out for speed, even when I quoted the attentuation figures and the higher SN margin. That's when I started to think about swapping provider.
I agree with Zarjaz that your IP Profile is high and slowing you down. It should not have risen like that from improving the wiring setup.
My knowledge is poor on profiles but here is my assumption: I was running on a 12db profile previously as my connection was continually dropping. When I improved the wiring set up I presumed I was creating more margin in the connection for the adsl signal and I could request a lower profile (6db) from Virgin and therefore get some more speed. Please feel free to correct me on this assumption, and if there is anything useful you guy's know, please share !
I'm more than happy to switch provider and have also been looking at Xilo LLU. Would it be correct to presume that if I swap from Virgin to Xilo (or some other ISP) and they are both buying the LLU connection from C&W at my exchange, I would essentially end up with the same physical connection as before in the exchange, but what I would gain is better support etc?
thanks again for your interest
