I've just received your e-mail.
Since the engineer visit, our IP profile has remained at 33.25Mbps and download tests have been pretty much a constant 30-31 Mbps, which is a slight improvement on what were were getting previously. I've kept a screen grab each day from the BT wholesale speed tester site.
However, I know our line is capable of a higher IP profile (it used to be around 40Mbps, giving us a download speed of between 37 and 38 Mbps).
I was hoping that the IP Proflie would have risen over the last week (router and modem have not been switched off and according to our router, there have been no dropped connections since 16:30 last Saturday).
I still wonder whether our profile is stuck as I would have expected speeds to have returned to what they were late last year.
As I said in my previous post, the line tests carried out by Open Reach indicated that the line was excellent with no faults.
I'd like to leave the case open for another 4 or 5 days and if our profile hasn't increased in that time, I'd like to try and request a profile reset.
I wanted to give an update to our speed issues.
Our IP Profile has remained at a solid 33.25Mbps since Sat 11th June.
Our download speeds look to me like they're now being limited by this IP profile. What I mean is that our download speeds are constantly around 32Mbps but I have a suspiciion that with a higher IP profile, the speed would be increased.
I still think our IP profile is stuck and feel that our line is capable of higher download speeds (based on what we were getting up until around December last year).
Since it's been around 9 days since our engineer visit, long enough for DLM to kick in, is there some way in which our IP profile can be reset. I realise that it will settle at the most stable speed but at this stage, I refuse to believe that we're getting the fastest download speed.
IP profile is a function of your sync rate, not the other way round. I.e your speed determines the IP profile.
What we really need to see is what your sync rate and max attain rate is to understand what is happening. Your IP profile won't change unless your line re-syncs at a different speed. If you have an Huawei HG612 modem rtaher than the ECI version, it is a fairly trivial matter to unlock it to view the line stats.
I received your voicemail/e-mail earlier. Apologies that I couldn't take the call.
I can arrange to work from home any day next week from Tuesday to Friday.
I wasn't sure if replying to your e-mail would mean that it reaches you so thought it best to post here and "mention" you!
Let me know what day best suits and I'll arrange to be at home on that day. AM is preferable to PM, but if PM slots are the only ones available, then that's fine.
Just to provide a final update to this issue.
A second engineer visit today has run a battery of tests, including visiting the cabinet to check througput, etc (we've remained at a solid 33.25 IP profile since the last engineer visit), but it looks like our line is giving the maximum it can. It has actually increased slightly today such that our download speeds are at around 32.5 Mbps.
No line faults were found (other than a false reading due to a call blocker which we use, which has been in place for around 4 years). I've since unplugged this but the engineer doesn't think it would be the cause of the problem.
At this stage, I'm not sure where the additional speed has gone, but I'm happy that everything that could be done has been done.
A special thanks to @NeilO for arranging the engineer visits and keeping me in the loop by phone. Also the Openreach engineers were both brilliant and did as much as they could to try and increase our speeds.
