Slower Broadband after Firmware SG4B1000E040

BeardyTimbo — Wed, 21 Oct 2020 13:16:17 GMT

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

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.

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.

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 — Wed, 21 Oct 2020 14:01:13 GMT

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.

Re: Slower Broadband after Firmware SG4B1000E040

imjolly — Wed, 21 Oct 2020 14:28:00 GMT

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 — Wed, 21 Oct 2020 14:34:18 GMT

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.

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

Re: Slower Broadband after Firmware SG4B1000E040

BeardyTimbo — Wed, 21 Oct 2020 14:43:46 GMT

Thats OK forums aren't the best way to communicate.

I think ignoring firmware put simply I'm not getting the speed advertised on my hub stats any longer.. the data speed is always liable to move up and down on the router over the months. But I always got the speed shown as I use wired connection, whether that was 23mb as shown today or 25mb.

My problem is despite what the data rates show is it seems to be locked and won't now go above a set data rate.

And yes this was since the firmware change, so perhaps the firmware hasn't causes an issue with the line but its caused an issue with me getting the data rate shown over the ethernet ports?

I logged a fault call earlier.. not sure if they did something back its now back to normal!

I have the same problem that after the firmware upgrade the speed has dropped by 4MB, and the attenuation on the line increased by about 15db. Can you please tell me where did you complain to ? Broadband fault or line fault ?

you may want to edit the photo/post as the photo contains a landline number which I am assuming is yours and this is an open forum.

Hi - I just clicked on the Test Broadband link via the router, then chose the option to log a fault for slow broadband.

Whether anything was changed or the router just "sorted itself" out following the firmware upgrade I couldn't say. The ticket hasn't been marked as resolved yet.

I must say I have received similar experience recently. My case:

I had 55/7 Mbps (by router Connection page). Actual speed was high 40's by 6+ (Speedtest.Net). The connection has been rock stable for maybe second year in a row.

Suddenly, first, disconnections began. When you're working from home, it's not a nice thing. So 8 or 10 disconnections. The speed dropped a bit, to 40/7.
Nothing has changed in wiring, I didn't touch the sockets and wires.

Then second, overnight, new firmware arrived, SG4B1000E040 with installation date 1-Nov-2020.

With it, speed synchronized became 6.40/5.00. Real speed is now about 5.4 / 4 by speedtest.net. Work became really difficult due to endless waiting for things to download.

VDSL available link speed is about 38k/8k. I am slowed down artificially by a BT limits.

My attenuation is now stronger by 10+ dB.

Router reboots did not help.

I raised the fault for frequent disconnections and slow internet.

@EastExpert Your noise margin would indicate a possible line problem, best to start your own thread.

EastExpert — Mon, 02 Nov 2020 21:42:09 GMT

Agreed, only thing why I decided to chime in, is nothing happened inside my house, only firmware change.

But, I am ready to admit that "after is not due to". So I'll see what happens tomorrow when engineer comes. Then probably start own thread as you advice, if it continues.

"After" was obviously not "due to" as you had a problem before as you admitted and have shown. TBH your post added nothing of value to the thread.

Let us know how you get on tomorrow in a post of your own.
