Another pleasant surprise today around 2-3 days after removing the home plugs

I've used homeplugs for years (early Devolo, 80Mbps?) and never had any bother with them, but my line occasionally switches between interleaved (~61Mbps) and fastpath (~67Mbps) and that post prodded me into having a look at my wiring...

I realised that the cable from the master socket to the modem (bog-standard flat twin) was actually laying on a homeplug... so I replaced it with a more sensibly routed length of Cat5.

After re-sync a speed test showed another 3Mbps . Could be coincidence of course, it'll be interesting to see if I get fastpath back in a few days.

Interesting. I have only recently had home plugs and see no adverse effect. My set-up: (All cat 6 cable)

bt modem --> Cat 6 cable to Sky router LAN port 1

LAN port 2 --> Home plug (in a surge protected extension socket) --> home plug upstairs --> Sky box (multiroom)

LAN port 3 --> back of my pc a few feet away.

I have not seen a decrease in speed since buying them. Are you people (who do have problems) plugging the BT HG612 direct into the home plug then passing the connection along to the router / pc?

Not in my case, it's basically not dissimilar to your layout.

The modem Ethernet port goes straight to the WAN port on the router and one of its LAN ports feeds a homeplug (direct into a mains socket, not via an extension lead) to run an A3 printer in another room (it's a bit big for the room where the computer lives).

The modem, router and iMac are also fed from a UPS which should stop any mains-borne interference from the homeplug.

If it does turn out to have been the reason for my fastpath/interleaved changes then it's almost certainly due to the modem (VDSL) lead being in far too close proximity to the homeplug... The wiring topology is fine, but the physical cable layout probably suffered from a moment's inattention last time I tidied up the rat's nest, which was longer ago than I'm comfortable thinking about .
