I am looking at a radio connection on my small local network, just to
the other end of the house and wondering what is the best way to go and
what hardware,linux compatible of course is required. A pointer to any
docs would be helpfull. I am asking here as I am not sure what I am
looking for.

Hi Lindsay,
The device you're looking for is a wireless bridge. It is a device which
connects to your existing wireless network, and you plug your wired devices
into it.
I have used this device for a project before, and it works well.

if you want to roll your own, have a look at wireless.org.au for usergroups
and local communities that will have the resources and links to point you
to the right sort of kit...

What's your end goal Ray?
If it's simply to make your network, wired and/or wireless, reach the other
end of the house younmight consider powerline ethernet
(ethernet-over-power) adapters.
I'm using them to overcome wireless drop out issues in the kitchen due to
the stainless steel splash back killing the signal. Mind you the config
software is windows based.

you could use a wireless bridge for that (possibly with an ethernet switch at
the remote end). or even a wireless AP if you don't mind the machines at that
end connecting via wifi.
alternatively, if your house is on stumps rather than a slab, it's easy enough
to string a single cat-6 cable from one end of the house to the other. if you
have a crimping tool so you can make your own cables, it can be done with only
two small & discreet holes in the floor. plug it into a second switch at the
other end and you can have multiple machines connected.
another alternative, which i've used in the past in rental houses, is to
carefully peel back the carpet in the hallway and run a cable under the
carpet. and sometimes wooden skirting boards have enough space behind them for
an ethernet cable. or run it along a picture-rail to keep it off the floor so
it doesn't get tripped over all the time.
best of all, though, is to get an electrician or qualified cable layer to put
RJ-45 points in every room in the house, all leading back to a central point
where you can put your switch and/or file server and/or internet gateway. i.e.
as close to your phone/adsl line or NBN or whatever connection as possible.
I had this done at home when I got the electricity wiring replaced back in
2000. IIRC it cost about $600 for about 12 points (dual RJ-45 sockets in most
rooms, including the bungalow)...but that was a) 17 years ago and b) done as
part of a much larger, more expensive rewiring job so would cost more these
days.
not having to buy a decent wifi bridge or AP would offset some of that
expense.

Thanks for all the replies, it was a good discusion, I'll likely go for
one of craigs suggestions, put a runner carpet down the hall with a
couple of cat 5 cables under it, then run it around the skirting board
to a RJ45 socket.
A likely problem with any radio is I live in a concrete block house,
with a suspended floor, all walls including internal are such blocks
further more the radio path concerned goes right through the bathroom
and kitchen, experience showing such construction is NOT radio friendly.
I never really considered ethernet over power as I do a of of medium
wave and shortwave listening (Note 1) and ethernet over power is murder
RFI wise on the HF bands.
Note 1: I currently have 3 recievers, A HRO 60 (I had to make 4 coil
box's for it),A Racal RA17C12 and Yaesu FRG7, the first 2 being real
outstanding recievers.

Just shorting out ethernet shouldn't cause any serious problems though, just
failure to connect to the network.
Was that PoE or mains cables that caused your customer problems?

That's correct. Ethernet is very well isolated and current limited. It's almost
impossible to damage a computer through the Ethernet jack.

Once the skirting board is off, with a medium breaking bar, or even a
cat's paw if the nails come out fairly easily¹, it can be enough to
deeply chamfer the lower rear arris with a (power) plane, if a router
isn't to hand, to make a nice fat rebate. There will also be much
greater risk of splintering tearout in old dry hardwood skirting board,
with the router. If it's MDF, then that's no issue, I figure. (I've only
dealt with hardwood, though.)
The router's handy for curving a groove up to the cutout for the RJ45
socket, but a nice sharp 6mm chisel can do wonders, whacked often
enough. Nobody will see the back.

Again many thanks for the replies, a couple of points from the various
responses.
I have 2 conflicting hobbies computors and MW/SW listening. I live by
myself in an isolated house in the hills in NE Victoria, this makes it
relatively easy for myself to set up the house for low RFI (Note 1). I
have found anything powered by compact switching supples (plug packs)
are murder RFI wise, this includes led and any kind of flourecent lights
. A desktop computor system is not TO bad if one has high quality power
supply case and monitor.
Experience among my friends for any kind of radio modem/bridge bit
radio/satelite/wifi internet has shown that these are appalling sources
of RFI.
My skirting boards are screwed on (concrete block walls) so removing
these and groving them are no real issue. Also its possible to get
rubber protection strips for running cable under carpets, Another way is
to run the cable along the outside wall, this being the easier, my
networks bridge and the remote station both being on the north wall
ofthe house.
Note 1: For low rfi reception one needs a GOOD aerial and a radio quite
earth ie NOT via the mains earth, its preferable that the radios aerial
input circuit is NOT connected to the chassis. A tuned loop is also an
excellent low rfi aerial, theses being somewhat easier to match to the
HRO and the Racal, both of which expect to see a low impedance resistive
aerial.

outside one day too.
DVB-T rtl-sdr dongles are so cheap it's hard to resist playing with

so do you do anything special for your (presumably large HF)

I'm planning a simple RG6 connection of about 5m before it goes into
the dongle. the short mast and dome are made out of fibreglass - I
figured the less conductive material high in the air the better.

Here's some guidelines:

A direct lightning strike is a non-trivial problem, as described in

NO, one simply disconnects all electronics from the aerial, it NOT being
possible for anything like that to service a direct strike. Note: I have
MUCH experience on dealing with lightening and its effect on
electronics.
