NEWBIE - Devolo Plugs (one room issue)

I have DEVOLO DLAN plugs in many rooms in the houses and am getting good speeds throughout EXCEPT for in ONE room where the speeds are poor...what can I do to fix this?

All the DLANs are plugged directly into wall sockets

Home Plugs are still subject to distance limits so it may be this is just the best you can manage in that room with them.

Solution would be to run Ethernet from a room with a good connection.

Thanks...did not know that
However...I have plugs in ajoining rooms (same distance) with great speeds

Have you tried temporarily moving one of the "good" plugs from an adjoining room to the room that is running slow? This may show if there is a problem with the plug rather than the wiring.

While the rooms are adjoining there is the possibility that the actual mains wiring distance is considerably different. Or there may be a noise source causing reception problems in the room.

As suggested if the plugs are all of the same model testing them systematically to see if one performs better in the 'slow' location is one option.

Is that one room a later extension, possibly with RCB rather than simple fuses?

No , same period as rest of house

Almost certainly wiring - I have a similar issue. The house has been rewired piecemeal - room by room as we do it up. Probably a mistake in hindsight - but too late now! This has left one room with very old (1960's) multi-strand mains wiring, which is apparently not good for powerline networking. Modern single solid core wiring is much better. Unfortunately this is the room with most of network connected computer kit! Struggling on with a Wi-Fi solution for the moment, but will be fixed when we get round to the renovation.

Wireless AC wifi range extenders are faster than powerline in my home.

Home Plugs use radio signals on the same range as VDSL
that can cause havoc with your internet connection i would go with a wireless ac bridge.

Use powerlines all around the house and have never had a problem of powerlines effecting the adsl, adsl2+ or VDSL services I have had over the years.

modern PLA�s use a sort of PLT in part of the radio spectrum in the 1.8MHz to 86MHz range. The gigabit versions operate right up to 300MHz
VDSL2 uses 25 kHz to 12 MHz
So its a could cause interference to VDSL just not in your case...
Also PLA'S could soon be made Illegal to use. its not just vdsl that can be effected anyone listening to am radio can be effected.. Sea and land rescue OPS have reported interference around 5/8MHZ in built up cities...
should a Stakeholder (radio user) become aware that they are suffering interference from PLT and request Ofcom's help to resolve the issue, there is every chance that Ofcom may come knocking at your door. To date, most instances of PLT interference have only been resolved to the complainant's satisfaction by removal of the devices.

i myself have experienced vhf radio service on 166Mhz on a council radio transmitter it was located in a block of flats in Glasgow the transmitter was a vhf repeater link. we had constant interference during the day and it was found that it was some tenant's using PLA�s that was causing the problem it took around 2 weeks to find the cause..

Sorry for the rant but i would just like to pass on what i have found and my own pernonal findings

Here is one report there are other google is your friend

Btw UK VDSL2 is power masked to not interfere with ADSL2+ so avoids the lower frequencies ADSL and ADSL2+ use, but does top out at 17 MHz.

G.fast looks set to push on towards the 120 MHz region.
