Re: Sync speed gradually reducing

Tested using 17070 with cordless phone both using home extension wiring and direct via the test socket and there is low level but perceptable "white" noise in the background and no hum in both cases.

Re: Sync speed gradually reducing

Re: Sync speed gradually reducing

Tested with corded phone and the noise is still there.

 

How do I go about reporting a fault? What information are they likely to need from me?

Re: Sync speed gradually reducing

Contacted 151 as you suggested and no fault was discovered on the line but it was agreed to send out an engineer to checlk the phone socket. Engineer arrived this morning and diagnosed a fault with the socket and replaced it.

 

Line sync dropped as low as 7.9 but has now recovered to 10.4. How long should I expect to wait before peak speed is achieved (somewhere between 16 and 18 based upon previous experience)?

 

Thanks for your help which is really appreciated.

Re: Sync speed gradually reducing

Stats taken from last occasion yesterday (26 Feb) when router restarted and after the engineers visit:

 

15:49:13, 26 Feb. (16152.680000) DSL noise margin: 5.90 dB upstream, 15.30 dB downstream
15:49:12, 26 Feb. (16151.660000) DSL line rate: 851 Kbps upstream, 10359 Kbps downstream

 

Is there any other data that you require?

Re: Sync speed gradually reducing

Your noise margin is very high at 15db as normal about 6db. If you can maintain connection for 3+ days then repost the 2 lines of stats and we can see if mods will reset noise margin back to 6db

Re: Sync speed gradually reducing

Just updating after about a week after the engineer replaced the main phone socket.

 

Latest figures from hub event log are as follows:

 

15:48:08, 07 Mar.(297527.270000) DSL noise margin: 5.90 dB upstream, 0.80 dB downstream
15:48:04, 07 Mar.(297523.240000) DSL line rate: 964 Kbps upstream, 18070 Kbps downstream

 

All seems to have settled down.

 

Thanks for all the helpful advice.
