Upload noise margin dropped so has upload speed ?


[link to this post]
 
this afternoon my router disconnected and reconnected 3 times in very quick time frame ( less than 5 mins)

these are my stats now
5. DSL uptime: 0 days, 01:26:42
6. Data rate: 15304 / 79903
7. Maximum data rate: 15461 / 96972
8. Noise margin: 7.5 / 10.7
9. Line attenuation: 3.6 / 4.4
10. Signal attenuation: 3.9 / 4.4

Before the drops my upload speed has always been 19999 and upload noise margin between 16 - 17 since i had fibre in September 2015 I am on a 80/20 product


As you can see the drops have not caused my download speed to change , what could cause a 10 drop in upload noise margin and why would that cause my upload sync to lower by about 4.6 meg?

many thanks

Some noise present in a narrow frequency band that is only impacting the upload frequency band

Plugged in any thing new today? Or got a neighbour with an adjoining wall who may have done so?

Hi , No setup has been the same since sept 2015 , no neighbour with an adjoining wall .

would it be worth trying another router and filter? , i just have the one master socket with a BT MK4 faceplate

If the noise that is impacting the upload , went away ( could it just be a burst of noise at that time of the disconnects, and doing another re sync bring it back up?) on its own accord, would i likely get my 19999 sync back ?
many thanks

No one can say for certain, but when noise does go away your modem will not automatically resync, you should see the SNR margin improve, hinting that things are better and a resync might be worthwhile at that time.

Best thing is to leave alone and see what happens to the upload SNR margin over the next 24 hours.
