Sync rate dropping.

I signed up with Sky, all went well and I was connected on the 25th February.

My estimated speed is 3.5Meg, my initial sync speed was 2045 kbps.

Since then I have had two sync events, the second sync speed was 1543 kbps.

This morning I have there has been another sync event, this time down to 1019 kbps.

Stats are as follows:

ADSL Link Downstream Upstream
Connection Speed 1019 kbps 796 kbps
Line Attenuation 52 db 32 db
Noise Margin 20 db 12 db

Is this just a case of wait for my 10 training period to come to and end or is it an indication of a problem?

The line in question is only about 6 months old and has the pre filtered face plate, no extensions or any other devices plugged into it.

Is sync remains at 1019 and margin is 20dB after a reboot, then looks like they've locked you to 1Meg

They being sky

I am in the middle of an ongoing saga with Sky regarding my variable,(decreasing), sync rates since the start of Feb. I am currently, within the hour, expecting a visit from the Open Reach engineer requested by Sky - we shall see what the outcome is.
When it is resolved - I will let people know, contact me for details on how to escalate your problem beyond the first level of support, worked a treat for me.

Well I have just rebooted the router and I am synced at..........
ADSL Link Downstream Upstream
Connection Speed 1019 kbps 796 kbps
Line Attenuation 53 db 32 db
Noise Margin 20 db 12 db

Is this worth chasing up with Sky as I am within the cooling off period I think, I would prefer not to get tied in if it means such a low speed.

What Sky broadband package are you on?

I am on the unlimited package, I knew when I signed up I would only get around 3.5Meg but I chosse that package due to the fact we both work form home and didn't want to worry about download limits.

You need to get Sky to reset your target SNR margin - it's too high.

After speaking to Sky they have arranged a Openreach visit for tomorrow.

Waste of time, Sky has control of the DSLAM, NOT Openreach

They did quote to you the terms of such a visit? ie If no fault found you will be charged?

Don't worry, I'm sure that the Openreach "£ngineer" will tell him. It's the first thing they say when you open the door.

Well there is a fault, I am fortunate in some respects that I have two line into the house and broadband on both.

The "good" line syncs 3.5 meg, the engineer checked and the physical route of both my lines is via the same cabinets back to the exchange.

The "bad" line is now syncing at exactly 2400kbps 51db 7db, it has be up for 28 hours.

The Openreach engineer ran out of time and was unable to explain the difference in sync speeds as at the cabinet, the bad line reports a higher attainable speed if that makes sense.

Question is what sync did he get at the cabinet?

If Sky LLU and 2400 sync at cab, then Sky DLM has put you on a fixed profile.

He said the speed at the cabinet should give me the 3.5Meg that was esitmated.

I have just had to unplug the router actually and it has resynced at.......

ADSL Link Downstream Upstream
Connection Speed 4320 kbps 800 kbps
Line Attenuation 53 db 31 db
Noise Margin 7 db 10 db

No idea what is going on to be honest now!!!

The 20dB noise margin is now 7dB, so you get more sync speed.

i.e. perhaps Sky has 'unfixed' your connection speed.

Just to share my experience with O2, showed a sudden increase in noise/errors/unstable syncs on the line over 3 weeks. Finally showed them it was nothing on the premises, router in test socket only tests etc.

BT engineer came round, tested the socket, found a crossover link causing high resistance on my line at my local cabinet, BT Wholesale engineer who was there weeks ago was made the scapegoat, in passing at least, problem fixed, O2 put me back on normal profile after I called them, sync back to normal from at it's worst 800kbps sync when I am now at full 8Mbit AND line now stable

Well all was well for about 150 hours and since then I have had lots sync events and I am back down to ........

ADSL Link Downstream Upstream
Connection Speed 1856 kbps 800 kbps
Line Attenuation 52 db 31 db
Noise Margin 16 db 10 db

Very frustrated now!
