Sky Broadband Hub - Stats meaning?!

[Sky-2022]

Hi, Sky Community. 

Would be great if I could get some advice and guidance regarding the question that I have been having trouble answering. I have seen from other threads that the headings - (Line Attenuation) & - (Noise Margin) with their figures are very important to show the broadband speed to the router. I am asking for both headings what they mean and what they should be the optimal numbers for the best connection and if there is anything to worry about? - I have attached a screenshot to show where and the information that should appear after approval.

Thank you!

• A reasonably understandable Google-type answer - The longer the line/higher attenuation the more noise margin you may need - which means the slower speed you will get. What's ideal or possible depends on your geography and the quality of the line.

Hey, @TechmanagerMal.

Thank you for your prompt reply, makes a little more sense to me. How does my stats compare to what you said, good, bad, decent etc?

Thank you!

@Sky-2022What does the information you get from filling out the link below, hiding the private information in the top-left when you take the screenshot, this will give us a good indication. But you can also do the same with the broadband test and click on " Tell me more about my connection "

https://www.broadbandchecker.btwholesale.com/#/ADSL/AddressHome  <<< gives indication of speed

Can you please run the broadband test, this can be done either via the Sky app on mobile data or use the link below.

Hey, @Highlinder.

I have attached 2 screenshots that should appear once approved, thanks for your help!

@Sky-2022So you are not far off your minimum, are you re-starting your router because of speed or is the router re-starting itself? As you should be getting way more as it says you can get between 62-80Mb/s

Hey, @Highlinder.

I have been facing many issues with my internet and it was at one point 69mbps access and then when it went bad it dropped to 52 and still having the same issues, I have been restarting the router every few days to see if it helps but no luck. And it hasn't gone back up since that day. 

I have had an engineer visit they were saying due to the 3 storms we had back in Feb it may have shorted my CCTV which is now overloading the router, but his instructions were to take out the cable every time we are home, where this a hassle as we can forget after a stressful day.

@Sky-2022 

The hub has been up for >130 hours without dropping.

The line attenuations are reflective of the speed in the wholesale checker (you would expect higher attenuation if there was an external fault)

@mae-3 would have more knowledge about whats happening in your case

@Sky-2022 

Oh and the 6.1db downstream noise margin does indicate the could be another 12Mbps.

[Sky-2022]

Hey, @cookiemonsteruk.

Thank you for the information as to my recent reply above, even when I have removed the CCTV cable from the router at least the router access line should go back up to 64mbps at least?

@cookiemonsterukThis is why I got @Sky-2022 to do the checks as looking at the speed there should have been a lot more.

@Sky-2022 

The first thing to do is not reboot the router every 2 days, just leave it running 24/7 without touching it and see if it ups the speed.

Technically, it would be difficult for Sky to accept a fault even though everyone on the forum would likely agree it is a faulty broadband line but you are above the guaranteed minimum speed.

The distance from the cabinet is around 260 metres, and for that distance on an average broadband line, one would expect about 65-70Mbps downstream and 20Mbps upstream.

Hey, @mae-3.

Thank you for your informative response. I will now keep the router on for 10 days and see if there is a change and will report back here with an update.

Thank you all @mae-3 @Highlinder @cookiemonsteruk  for the help!

[Sky-2022]

Hi, Sky Community. 

I am back once again with the update, post 10 days. The speeds have still not changed and to be honest, I could do with guidance regarding this, please? I have the updated screenshots once they are approved for viewing and verdict. 

Thank you for any help once again!

@Sky-2022 

It's very difficult to advise anything more other than leaving it for another 2 days, the WAN shows an uptime of 8.5 days approximately, leave it for another 2 days and see. But in the end, even though I absolutely agree you have an issue and likely fault on the broadband line it is achieving a speed above the MGS and therefore Sky won't accept it as a fault.
