Re: Sync speed gradually reducing

Your noise margin is very low - is it affecting your download speed? If it goes any lower your router will probably reset

There was a reset at 15.48 today was that a manual reset or router dropping connection?

Re: Sync speed gradually reducing

Thanks for the reply.

 

The line sync speed has been rising around 16.6MBps to a peak of 18.1 on 7 March but has since fallen to about 14.5MBps today (9 March).

 

The reset that you mention was not a manual one but a dropped connection which has happened a few times randomly in the preceding 3 or 4 days.

 

Why should a low noise margin result in a possible reset?

Re: Sync speed gradually reducing

There havwe been no further connection dropouts since 7 March so I carried out a manual reset today (11 March). The event log showed the fiollowing:

 

16:36:31, 11 Mar. ( 98.280000) DSL noise margin: 5.90 dB upstream, 3.00 dB downstream
16:36:30, 11 Mar. ( 97.170000) DSL line rate: 1176 Kbps upstream, 18453 Kbps downstream

 

The line sync has risen from 14.5MBps to 18.4MBps after the reset.

Re: Sync speed gradually reducing

maybe it has stabilised now  just need to monitor and see if it remains stable and also watch noise margin and see how low it drops.  the lower it drops the more likely that your download speed will slow down and if it goes <1db then a reset is probable
