Well you can see you can upgrade to FTTC and get expected range 49/35mb and the your cabinet is available. Huge difference to your current 2/3mb
if you decide to upgrade then phone options team and see what deal you can negotiate 0800800030
Thanks again @Keith_Beddoe . The information you've provided is very interesting and very useful.
In particular I was intrigued to learn that the Home Hub 4 is more suitable than the Smart Hub 2 for an ADSL service, since I am actually using a Smart Hub 2. I think I have a working Home Hub 4 somewhere though and will give it a try. I do however vaguely recall that I'm on ADSL2+.
It's also very useful to know more about the different relays that are used, and the plethora of joints in the exchange. And I'm pleased to now know why the upstream speed seems to suffer the most during episodes of noise. When it does so I can indeed hear the noise on the phone.
looking at your stats you are on adslmax but a change to adsl2 would not help your down speed but would improve your up speed - vdsl is way to go to get better faster connection
Thanks to all who helped me by posting replies to my post.
I recently upgraded to Fibre 1 and have been very pleased with the results. Aside from the higher bandwidth, which will certainly be useful, the service has been stable which is what I needed most.
I availed myself of a 'January Sale'. or some such, and was pleasantly surprised at how little extra the new service costs. It's a two-year contract, and I was also able to switch to an Anytime deal for voice minutes. This is a great improvement on my previous evenings and weekends calling plan, not least because I'm not now charged punitive rates if I talk for more than an hour.
