Download speed halved, upload still good

[#1]

Something a bit odd is happening with connection speed.

When it is acting 'normally' I get d/l 10 - 11 Mbps down and 1 Mbps up.

For a while the d/l speed has been lower and I've been seeing a number of connection drops.

I have done a quiet line test and it is fine

I have done soft re-set and disconnect/reconnect

I have a 3 femtocell mobile point and develo wifi powerpoint connector plugged in to router. Line speed was OK with these in place.

Fiddling with wiring makes no difference - it never does.

We've had a couple of power cuts in the last week or so, so my guess is that the line needs to be re-set to training please.

SNR values look a bit icky

Hi bin,

Diagnostic tests aren't indicating any issues. Would you be able to do a speed test whilst connected directly to the router over ethernet?

Testing your line isn't showing any obvious faults, the line stats other than the sync speed look good.

	Upstream DSL Link Information	Downstream DSL Link Information
Loop Loss:	19.3	34.5
SNR Margin:	7.1	5.8
Errored Seconds:	4	1
HEC Errors:	0
Cell Count:	0	0
Speed:	1259	6639

Maximum Stable Rate (KBPS):	11360	Fault Threshold Rate (KBPS):	9088
Mean Time Between Retrains (Seconds):	86400	Mean Time Between Errors Upstream (Seconds):	1763
Indicative Line Quality:	G	Mean Time Between Errors Downstream (Seconds):	1964

The SNR is where I'd expect on a 6db target and should be fine for your line.

Have you tried a resync rather than just a disconnect/reconnect? If not, try a single restart of the router.

Hi

Testing on cable makes no difference - flat 5Mbps.

I have done soft reset and hard reset - where do I find Resync on the TG582N?

Thanks

Bump????

[#6]

Just power it off for 30 seconds and then back on.

I've done that - again - still no improvement.

OK I guess I'm lucky compared with many, but having had 10-11Mps for the last year or more it's a bit of a pain finding I've been throttled back to half that value. Why?

bump??????????/

Hello?? Is anyone there????

[#10]

Sorry for the delayed response.

Your not being restricted as your current profile is "WBC 160K - 24M No delay (INP 0) 3dB Downstream, UC No delay (INP 0) 6dB Upstream (ADSL2+)".

We'd need you to raise a fault here so we can get this looked into.

Well, here we are a few weeks later and no progress.

Ticket was raised and someone said they had done something to put the line SNR back up.

That change never happened and it was supposed to have been redone over the weekend - nothing happened.

If that didn't happen it reads as though I then had to go back through the chat team and start again - I'm not sure why since if the backend team have the problem surely they should own it till it has been resolved.

Anyway - once again I'm deafened by the silence so would appreciate any possible guidance from anyone on PN team who could please advise what I should do next.

Thank you.
