Just moved into new place, cottage with tiled floors, thick walls and no
prospect of running cable neatly. Wireless works but only get 10Mbps.
So looking for recommends for powerline adapters. Quality and
I use them to link to my backup drive in the detached garage.
I started off with Devolo units which I selected partly on the fact that
they had flying leads rather than being of the huge wall-wart variety.
They worked OK but one failed after a year or two, and when I bought a
replacement that didn't last very long either.
Then I bought a pair of TrendNet TPL-401E units, which *are* large
wall-warts, but I also have a TrendNet wireless router which has
impressive performance and reliability so I trusted the brand a bit. The
powerline adapters work extremely well and I had to scrabble under the
desk to see what they were because I haven't given them a moment's
thought since installing them a few years ago.

Is that with the AP placed in a good location for it, like in the
apex of the roof so it can "see" down into most of the building
through the floors or sat under a desk in a rats nest of cables
against a wall at one end of the property where the phone line just
happens to be?
I'd try really hard to get cables in but then I also want to listen
to HF radio, failing cables WiFi but with the AP (just the AP, not
modem, router, switch and AP all in one box) sited for coverage not
convenience, last resort powerline...
There isn't one. Ceilings taken up to rafters, celotex and insulation
behind. Velux skylights. Lovely in summer :-)
The run is awkward (I want to get from downstairs to upstairs), it would
mean drilling through two 3ft thick walls, and box conduit would be very
visible even if painted over. No covings to try and thread behind.
Going out through the 3ft thick wall, round the outside (hidden under
bell casting at bottom of render) then up the wall and in is a
possibility but a lot of work and I CBA.
There isn't one :-) Stack is external
Almost line of sight. Full signal strength shown. Adapter in the PC is
only b I think, and it's not upgradeable (Asus eeePC). Conversely, it
has 100Mbit hard wired ethernet.
I'd love to. Last place I was in had suspended floors, when the heating
engineers installed a new CH system, I took advantage of the lifted
boards to run Cat5 everywhere with patch panel in the understairs
It's not going to be that easy in this place :-)
That's where I am, last resort. Apologies in advance to any radio
amateurs in the vicinity.
Rather than moaning about it and being "dog in the manger" I'm firmly
of the opinion that we should be working with users and manufacturers
to mitigate issues. Personally, I suspect something as simple as
ferrites on the ring main at the distribution board would lower the
incidence of interference vastly. If you keep the RF on the balanced
parts of the mains (flat twin and earth isn't that bad) and stop it
leaking into coaxial supply lines, in theory there should be very
Needs experimentation and co-operation, though. I'll make no bones
about it, radio amateurs can be a stubborn, uncaring lot and we do
ourselves no favours with this attitude. When someone starts throwing
the "ban" word about they've usually lost all sympathy they may have
Tesco Value .sig: Simple, no-frills irony guaranteed.
Wouldn't that attenuate the powerline signal, and prevent it
transferring across rings on different breakers/circuits? Similar
thing to when the makers of the adapters tell you not to plug them into
surge protected strips, as the surge protection kills the signal.
RF chokes on the cables between the CU and the meter? Making a few turns
might be a bit tricky though :-)
Quite right, but if you think about it, confining the signal to the
ring main for the sockets is a double whammy: You're not radiating
interference and it also keeps some interference from the utility feed
out of your ring main.
Multiple turns isn't really a problem as long as you can get a large
lump of magnetic material onto the cable.
That's an idea, although we want equal and opposite not to be affected,
while blocking common mode currents. That means both conductors need to
pass through the same former. I've not seen clip-on ferrites that big :)

Is 10 Mbps a real limitation? How fast is your incoming internet? and
an eeePC isn't exactly high powered either so would not make full use
of 100 Mbps if shifting large files locally.
It is actually dot-and-dab and plasterboard on old brick walls, but the
gap is filled with polystyrene insulation. I've managed to do a couple
of short runs, to add sockets and a wall light, by poking cables through
the insulation, but a long one (floor to ceiling) isn't gonna work.
Did think of that, but the door's in the wrong place. To get the cable
to where I want it downstairs, I'd have to come down behind the door
(which is in a corner), and right around the perimeter of the room.
Solid floors, no skirtings. Then upstairs, there's a doorway and a
fireplace in the way, and an engineered wood floor which I'm not ripping
Yes, I stream video and music from a media server, and run nightly
backups too. It's probably perfectly safe, but I don't like running
backups over something as ephemeral as wireless.
Not relevant as I need the link for media streaming and backup, not
internet, but it's ~13Mbps. FTTC cabinet has just arrived in the
street, and the BT line checker promises 79Mbps :-)
The eeePC displays stuff from a media server on my big TV.
The media server and backup server which will be going on the other end
of the link. They have gigabit interfaces but if I can get 100Mbps over
the powerline adapters, I'll be happy.
Trust me, I would very much prefer a cable, but have a lot of other
things going on right now. Will revisit it when I'm settled and have
Yes, *of course* 10Mb/s is a limitation.
I'm not sure that running backups over wireless should worry you,
though, unless the volume being backed up requires greater bandwidth.
Yes, wireless is less reliable than Cat6 ... but not much less
reliable, and I'm not sure that I'd regard powerline as being any more
I have 2 TP Link adaptors and find that they work as expected. I've had
them in use for over a year now, and they still work as they should.
I used to use a TP Link router which worked great, so that's why I went
for the TP Link brand.
I've got Ebuyer's own brand adapters which work well but seem to go out
of stock frequently (as they are now!).
Whichever you get, try to get pass-through adapters to preserve the 13
amp socket you're using.
We've been using a couple of TP-Link 5-port gigabit switches on our network
for 18 months now, had no problems at all, they have been running 24-7
since we bought them. Cost was not much more than a tenner each.
