Upload speed reduced by 50% over last 6 months

Over the last six months, my infinity upstream speed has dropped by 50% to only 4mb/sec. This has taken two massive dives on single days, rather than making a steady decline.

I know this as I have a samknows broadband monitoring unit which uploads my performance and can prepare graphs on the website dashboard.

How can I get BT to review the cabling to my property in the access network? It would seem two distinct events (perhaps provides in my cabinet) have disturbed my line.

Re: Upload speed reduced by 50% over last 6 months

Hi portal,

 

If you have a BT Home Hub 5. Please post stats. Go to http://192.168.1.254 > Troubleshooting > Helpdesk.

 

Please post BT DSL Checker results. Remember to delete out phone number. https://www.dslchecker.bt.com

 

Please do a BT Speed Test and post results. http://speedtest.btwholesale.com

 

Is the router connected to the test socket or an SSFP?

 

Have you completed a quiet line test? If not, dial 17070 and select option 2. The line should be quiet.

Re: Upload speed reduced by 50% over last 6 months

Hi, sorry, I don't have a BT HH5 - I run an Asus RT-N66U.  Always have.  That's not changed.  I don't believe it's possible to get line stats from this.

 

However, here's the other stuff:-

 


Telephone Number 01473xxxxxx on Exchange KESGRAVE is served by Cabinet 3

Featured Products
Downstream Line Rate(Mbps)
Upstream Line Rate(Mbps)
Downstream Range(Mbps)
Availability Date
HighLowHighLow
FTTC Range A (Clean) 32.4 22.4 7 5 -- Available
FTTC Range B (Impacted) 25 12.6 6.3 2.7 -- Available


1. Best Effort Test: -provides background information.

Download Speed
28.2 Mbps

0 Mbps 28.89 Mbps
Max Achievable Speed

Download speed achieved during the test was - 28.2 Mbps
For your connection, the acceptable range of speedsis 20 Mbps-28.89 Mbps .
Additional Information:
IP Profile for your line is - 28.89 Mbps

2. Upstream Test: -provides background information.

Upload Speed
4.05 Mbps

0 Mbps 10 Mbps
Max Achievable Speed

Upload speed achieved during the test was - 4.05Mbps
Additional Information:
Upstream Rate IP profile on your line is - 10 Mbps

 

This stuff looks fine.  The issue is the 4Mbps upload speed.  This is significantly less than a few months ago.  From the graph below, you'll note 2 or 3 distinct reductions in speed which happen instantly.  This is therefore a change in something, and not a slow degradation.  To my eye, my line has been disturbed in the cabinet, twice.

... and the line is quiet on the test.

 

The graph above is from my SamKnows dashboard.  I have a monitoring device on my network.

This 2nd graph better shows the upload speed reduction from 6.5Mbps to around 4Mbps.

Re: Upload speed reduced by 50% over last 6 months

Hi, thanks for the reply.  So is it a case of "No Home Hub 5, no diagnostics?"

 

Anyway, I've managed to get some line stats off the Openreach modem, which I'll post below.
