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.

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.

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. Lindsay
