The download speed on our Plusnet broadband connection has dropped dramatically, from a consistent 15-18Mbps to around 200kbps. So it has gone from being very satisfactory to hardly usable. Two things that seem quite odd:
1. The upload speed seems unaffected. We can still sometimes achieve over 1Mbps.
2. The neighbouring property, which shares a cable (approx. 700m) from the main BT line on the nearest road, still has the consistent 15-18Mpbs.
Unfortunately, I can’t say exactly when the problem started, as the place was unoccupied for a while due to a combination of the pandemic and building work. But I do know that it has been like this for at least a couple of weeks.
This is an ADSL2+ line. BT’s broadband availability checker shows an expected downstream range of 7.5-17.5 Mbps.
We have the white 2704n modem. On the xDSL statistics page it shows:
Current rates: 288kbps / 446 kbps (downstream / upstream)
Attainable rates: 11564kbps / 1099kbps
SNR margins: 42.1 / 26.6
Attenuation: 26.5 / 14.1
Output power: 15.8 / 12.1
(The neighbouring property, which is currently at around 17Mbps download, has SNR margins of 3.1 / 6.4.)
If it would help, I can post a screenshot of the whole statistics page and can obviously let you know the ‘phone number if you can tell me how to do that privately.
Any advice or suggestions as to anything I might try would be greatly appreciated.
Thanks ….
