Understanding High Signal Attenuation

[#1]

Just installed a Hub 2, and wondering whether some of the info it shows may "explain" the dropping of our broadband download speed.

2 to 3 months ago our line went down to 1Mbps and the Openreach engineer -though not-doing-anything- made our line to go back to 12Mbps for a few weeks. We are about 1.2 km away from the street cabinet, just outside a small village in the country side.

I noticed in the Hub info below there is a max download speed at 14Mbps whilst the actual download speed is at 7.9Mbps.

SNR is not good but not that bad, but signal attenuation seems quite high for the distance to the street cabinet: am I reading that right?

@itlity 

For reference, I am 50 metres from "our" cabinet. My router stats say:

Line attenuation:   2.1 / 4.5

Signal attenuation:   2.1 / 4.7

@itlity A question - are you on an ADSL or FTTC connection? Those figures suggest ADSL to me, but I could be wrong. Of more concern than your attenuation figures is your DSL uptime of only 37 hours - this points to an OR network issue, irrespective of connection type. I will post below my 'help us to help you' script, and await your response before saying much more.

For Community members to be able to help, information from these two sites, as screenshots, posted as pictures within the topic, not as attachments:-

BT Broadband(obscuring your phone number) and BTW Performance Tester - Over a wired (Ethernet) connection if at all possible, please report the 'ADDITIONAL DIAGNOSTICS', and sight of the broadband connection status from your Hub (with the 'Username' obscured) would be a good starting point.

For the Hub One -

Navigate from the Home Screen to Troubleshooting > Helpdesk

For the Hub Two -

Navigate from the Home Screen to Advanced Settings > Technical Log > Information

It may also be a good idea to report the results of a Quiet Line Test - dial 17070 option 2 from a (preferably corded) phone. After the confirmation of your phone number, there should be total silence apart from the regular 'Quiet Line Test' announcement. Any other noise - report a PHONE fault first.

If you are unsure about any of the above, please just ask - I am happy to help.

Thanks for the reply, and script!

I am indeed on an ADSL broadband.

Up time is short as I installed the hub 2 on Saturday morning and router restarted by itself at about 00.30am on Sunday.

Will provide the tests results tomorrow.

Cheers for confirming your connection - the u/s speed threw me as it is a bit high, given your attenuation figures and the capabilities of ADSL.

@jab1 

The Hub Two Technical Log extract shows VLAN 101 isn't that FTTC ?

[#7]

@Dan_the_Van Good point, but I'd rather wait until we have a bit more to go on before saying much more - one piece of a jigsaw is not very useful.

@itlity 

To provide a bit more detail you could run your phone number in the following.

Post a screen shot of the results, including the narrative. Remember to obscure your details.

@bmc Already covered in my 'help us to help you' script, posted above.

[#10]

@bmc 

That has already been requested

@jab1

Over the years in support I've seen many a diagnosis go wrong because of an assumption, just helping to ensure this doesn't happen here.

[#11]

Fair enough, @Dan_the_Van - hopefully the details I have requested will make a full jigsaw. 😉

[#12]

@jab1 

Sorry - mis-read your post and didn't realise you were speaker about the Checker.

@bmc My 'help sheet' is always the same - it would be a macro if I could remember how to create them.

[#14]

@jab1  if the stats show VLAN 101 it must be FTTC, however  the OP who seems to think it is ADSL will not be responding until tomorrow.🤔

[#15]

@RealAleMadrid Agreed - after Dan's query earlier I refreshed my memory. When I get all my ducks in a row (all the requested data) then I'll have another think, but my current thinking is the OP is in a very rural location, with a looong copper wire, but still with problems , looking at the 'current' and 'attainable' d/l figures - and a couple of other stats on that grab.
