Short version. Changed ISP in December.
Before move was with EE (FTTC) and stable at around 60Mbps. The cable length is approximately 550m from the cabinet as measured by Openreach.
I moved to Pulse8 as they offer a monthly rolling contract with a fixed IP address. Openreach recently put fibre down our estate but it could be 6 months before it is available so monthly contract is best.
After move, everything worked fine for a week or so. We then got a dropped connection for a couple of hours. The next day it dropped again and came back on at 1Mbps, sat at that for a few hours and eventually after rebooting the modem/router (Zyxel VMG8825-B50B) it came back up.
I reported a fault as the connection seemed to be slow and dropping at times but was going back up to 58-60Mbps.
Openreach engineer came out. Tested line - No faults, checked DSLAM and changed my connection to new ports. Speed dropped to 48Mbps. He then left and didn't come back.
I am now on my 6th or 7th Openreach engineer as none of them can fix the issue. Every time they come out they test the line, change the ports and still no speed difference. I have been told by one of the engineers that the fault lies at teh DSLAM as the speed to the DLSAM is 80Mbps as soon as it goes onto my line it drops to around 48Mbps. One engineer even tested the line in the street ducts between me and the cabinet and the line is perfect.
There is a second cabinet in the same location which has 110MBPs coming into the DLSAM but Openreach will not move me to that cabinet.
I have been advised by Pulse8 that as the cabinet I am on is full, should I move to another ISP I would probably be given a connection in the other cabinet.
My line is on a 80/60Mbps profile with a DLSAM reporting I should get between 80 - 67Mbps with a DHT of 60Mbps.
Yes, I can move ISP but don't want tied into a contract as I will take the FTTP as soon as it is available.
How do you go about raising this issue with Openreach to try and get the faulty DSLAM replaced or what else can I do?
48Mbps may seem like a good speed for some but as an example, 2 people online, my wife watching low res training video, me watching 1080p YouTube video and downloading a software update and everything grinds to a halt with both videos and download failing/buffering.
I am now waiting on my 7th or 8th or whatever engineer to come out to tell me the line is great and that the DSLAM is faulty.
I told you this was the short version.
