I've recently joined Talktalk on a fibre package, the minimum estimated speed on signup was 69.6Mb, we were given a date for a technician install, which was later downgraded to a self-install, with no option to ask or pay for a technician install... however...
The rate never went above 48Mb until we changed from the supplied 'super router' to a Cisco 887VA, we then hit 52Mb, and stayed there. Finally decided to call india who provaracated as to the cause for some time, until I pointed out there was noise on the line, once he noticed it, there was no problem logging a fault, although the first appointment came and went with no-show from any Openreach technician, when one turned up, he did find several poor connections and some 'blue beads' which were removed.
So now we have a clear line but the Openreach tech. stated that as it was a 'line fault' he couldn't ask the NOC to reset the DLM on the line...
so to the question - given the above, is it possible for Talktalk to require Openreach to reset the DLM given the causal effect of low line rate being defective infrastructure, or will I have to wait and hope the line recovers over the next < six weeks?, the line rate is now down to 46Mb due to the fault-finding and rectification efforts with an interleave of 8mS
I know it's a real first-world problem, but given the rate is barely above the lower speed/cost tier, it's irritating!
