our broadband speed has dropped significantly a few days ago and it hasn't gone back up.
Miraculously I got through to BT call centre, which ran some diagnostics and instructed me to reset my hub (4) to factory settings. Perhaps unsurprisingly, this doesn't seem to have helped.
As an example, in the past I was always getting between 4.5 - 7 Mpbs on download and around 0.9-1 Mpbs on upload (sometimes lower.)
All the tests from the last several days are similar to the below (as you can see they've just been going down):
|00:29:50, 27 Jul.||( 3900.200000) DSL noise margin: 5.90 dB upstream, 12.50 dB downstream|
|00:29:49, 27 Jul.||( 3899.290000) DSL line rate: 312 Kbps upstream, 1304 Kbps downstream|
Nothing has changed in the set up, position of the hub, any other devices that may have impacted this. The router is already in the optimal position.
I know my line is poor quality already, but this is quite a significant drop for what seems like no reason to me.
I also know there have been multiple issues with surrounding exchanges - is it possible something was reset during a "repair"??
Thank you in advance for any insight.
Solved! Go to Solution.
Yes, the hub keeps restarting by itself.
I called the quiet line- no noise (or rather a VERY quiet hum.)
I'll be able to take a look at your connection and run a few checks on your line. Please can you send me in your details using the "Contact The Mods" link found in my profile?
Thanks for sending over the details. I tried calling today, sorry I missed you. I've run a few diagnostics and can see the connection has recovered. The noise margin will adjust automatically if it remains stable. I've opened a case to monitor this but if you see any changes at your end please reply to my post and I'll look into it for you.
Thanks @DavidM. Unfortunately it's not looking great again:
21:42:22, 01 Aug. ( 104.020000) DSL noise margin: 13.20 dB upstream, 5.10 dB downstream 21:42:21, 01 Aug. ( 102.990000) DSL line rate: 443 Kbps upstream, 2679 Kbps downstream
Speedtest results are looking worse again (ca. 5 Mbps is what we normally get)
From the logs I can see someone from BT(?) was checking our line tonight.
Will be grateful for any advice.
