Router Problems / SNR reset

Hi everyone,
I've had a more stable line recently with my new Billion 7800N router. However, it went wrong today for no reason and the DSL would not sync for hours. I tried a different router and that worked fine.
Anyway, after reflashing the firmware, restoring to default config settings and lots of resets I've got it working again.
Problem is, my SNR margin has gone from the standard 6db to 9 or 12 now I think, because BT obviously think I have an unstable line. My connection speed is very slow.
So could you reset my margin back to the default 6db please?
Many thanks.

Hi mike0381,
Youyr target SNR margin has indeed increased to 12dB due to those disconnections. As your line is now stable I have submitted an SNR reset. This should take effect within the next 24 hours. Keep an eye on those disconnections.

My line was incredibly unstable a couple of days ago. It's now much better but I'm still only getting 2.3 megs instead of the 3 megs which BT assure me I should be getting. Maybe my SNR needs resetting?

Hi tijara33,
Your current sync rate is just short of 3Mbps and configured to 12dB target SNR. Your line is very stable but your loop loss is nearly 60dB. I'd say if we reset your line the boost in speed would be temporary. If your line remains stable the Dynamic Line Management (DLM) system will lower your target SNR margin automatically causing a boost in speed.

But that will take at least two weeks of completely solid connection with low errors.

@Gigabit,
The DLM should make changes following a maximum of 120 hours stable. It does however depend on the error and retrain rates. All lines are constantly monitored for drop outs and errors. Depending on the levels of both an Indicated Line Quality (ILQ) is calculated. ILQ is split in to three main categories Red, Amber or Green. DLM makes improvements with an ILQ of Green which requires your line to error less than every 7 minutes and drop sync less than every 4.6 hours. A stable line that is error free should be ILQ Green the majority of the time.

Alex, Thanks for your feedback, I'm learning all pf the time. I'll leave everything alone & see what happens. I'm hoping to change to fibre at the end of September when my exchange becomes fully available. Presumably this will make a huge difference????

Unfortunately we don't have any estimated Fibre speeds for your line as yet as the exchange is not enabled so I can't give you any predictions at this stage. That being said, the majority of customers see a significant improvement in speeds when switching from ADSL to Fibre.
