Slower Broadband after Firmware SG4B1000E040

[BeardyTimbo]

Hi all - my router restarted just now and looks like its installed new firmware SG4B1000E040. Since then my Line attenuation and signal attenuation have increased a fair bit and now my broadband speed has dropped more than 20% from 25mb to about 18-19mb. That doesn't sound like a lot I guess but I am working from home and it is having an impact.

See info from router below.. I don't have a land line to plug in and check quality of line (for crackles etc). Also the box I connect my router to is a Mk2 so it doesn't have a test socket. Any ideas?

according to stats you have 22mb connection with a 23mb attainable and noise margin down at 3.1db suggesting G.INP active

which master

[BeardyTimbo]

Hi there - thanks for replying its appreciated. 

Yeah despite the data rate shown since the restart the max I have managed is 19mb or there abouts. Thats wired direct into data port on router. The data rate used to be around 25/26

I have the socket shown in number 6 on that list.

[imjolly]

so just to confirm if master no 6 then you do have a test socket behind the faceplate

enter your phone number and post results

Oh ok is it behind the top bit perhaps then? The bottom bit if I take it off just has a socket for a phone not an RJ11 which my broadband uses.

[imjolly]

your connection speed is about the same now as it was on 16/10 before the firmware update  it is also well within your expected speed range

[BeardyTimbo]

Ok thanks yeah I can see that says 22.66 observed on the 16th, and I'd expect some fluctuation in results.

However I do usually get a solid 25/25mb and have done for the 2 years I lived here. The 19mb I am getting now on every single test (whether that is due to firmware or not) is a fair amount lower than my norm.

I realise BT have their stay fast range but I posted here as I hoped someone could help explain the sudden drop. Granted the firmware could be a red herring although I do now see other posts with people posting similar issues after this firmware upgrade earlier in the year.

[imjolly]

but as can be seen from dslchecker results your speed is the same now as it was before the firmware update so the firmware update is a red herring as far as your connection speed is concerned

[BeardyTimbo]

I think you might be  missing my point.. I'm also not convinced the firmware made any difference but what I do know is prior to the firmware and subsequent reboot I got a solid.

25mb

now I get 

19mb

Somethings changed I dunno what, thank you for your help though your troubleshooting steps were helpful but my original issue remains. 

[imjolly]

sorry to labour this but your firmware update was today but your speed on the 16/10 is the same as the speed currently shown by your hub stats so how can firmware be the problem if speed just the same before and after
