Do they need a reset?

You should still get a link light between an ethernet device (homeplug) and an ethernet switch (in the home hub) even if the software / encryption key between the two homeplugs is lost/corrupted.

First thing I'd check is that the hub and adaptor don't have the same Lan IP.

So far, it appears that I have a reasonable connection & it seems to be faster than the previous O2 connection.

My last O2 Speedtest

My first BT Speedtest

The results from the HomeHub are:-

Connection Information
Line state: Connected
Connection time: 0 days, 06:47:49
Downstream: 21.31 Mbps
Upstream: 1.148 Mbps

ADSL Settings
VPI/VCI: 0/38
Type: PPPoA
Modulation: G.992.5 Annex A
Latency type: Fast
Noise margin (Down/Up): 2.9 dB / 6.4 dB
Line attenuation (Down/Up): 8.5 dB / 5.0 dB
Output power (Down/Up): 20.0 dBm / 11.5 dBm
FEC Events (Down/Up): 0 / 0
CRC Events (Down/Up): 4 / 6
Loss of Framing (Local/Remote): 0 / 0
Loss of Signal (Local/Remote): 0 / 0
Loss of Power (Local/Remote): 0 / 0
HEC Events (Down/Up): 32 / 2
Error Seconds (Local/Remote): 8 / 12

That's exremely interesting, as to me it suggest upstream throttling. Which is what they did on P2P upstream 24/7 when downstream was only suppoosed to be throttled at busy times. Upstream throttling capable of course of affecting downstream P2P.

Throttling or swapping downstream and upstream freq's? Less upload on BT but more download. Could simply be down to different vendor DSLAM and how it approaches the bins used. Unless Annex M was enabled on the O2 line which should have worked on such an incredibly short line!

Yes, I thought that it was notable that the upstream throughput was significantly lower than the upstream sync speed, particularly when I was achieving a higher throughput (on lower sync) with O2.

However, bottom line, the 600 upload is more than fast enough for my purposes &, hence, I'm not really bothered (other than for academic interest).

I think my son uses a fair bit of p2p & this might affect him but, when on O2, that was heavily throttled & the effective BT throughput is still much faster!
