Hi All,
Just signed up today but have been reading up a lot recently. I'll cut straight to the facts!
1. Signed up with Sky Fibre last year 40/10 and got the 38Mbps for 4-5 few months not a problem. I was provided with an ECI modem.
2. Started to get periods where interleaving was applied and sync was dropping to 28Mbps, but returning to 38MBps a few days later.
3. One day, sync dropped down and stayed at 18Mbps. After a week of this, I rung Sky to try and get on their fibre pro 76Mbps service. BT wholesale line checker was quoting me 55.1Mbps. Sky said they couldn't provide the Fibre pro so I changed over to BT Infinity2.
4. Received a text saying no engineer visit required as I already had a modem etc. They sent a Hub4 through the post.
5. On provisioning day, sync was..... 18Mbps!
6. Started to complain to BT retail.
7. Got an engineer eventually that reset DLM on the line. He used his J-something test device to confirm a 80Mbps sync with no errors on the line. He also did a pair test and that came. back all fine
8. A day later, I was down to 60ish
9. A day later, I was down to 55ish
10. Now I'm on 35ish
... not the quoted 55.1 mbps.
11. I bought a HG612 off eBay and unlocked it. I then found out that my cab is not an ECI cab (examining the band plans).
12. I thought as the line was fine at the time the engineer was round, it must be REIN or another type of interference. Being a radio ham, I have some HF receivers, but setteled on using a basic AM radio to hunt out noisy power supplies / appliances in the house. I've switched most things off now and relocated the modem away from other electrical devices. I've also disconnected the extension cabling from the master socket.
13. I've started to log stats which I have attached here. I'm sure I should be getting a faster sync than what I've got. My DS signal margins are ~16dB so scope for more sync hopefully?
14. What should I do next? Contact BT and complain again? I guess I may now be banded and stuck at this speed without an engineer visit?
I'm in Sale, Manchester if that means anything.Any help appreciated thanks!
