| Their performance depends on the electrical wiring in your

|
| Ironically for me I've only managed to make them work on older

|
| In my current house (newly built 2018), I can't even get them

|
| If you've got an old house with old telephone wiring, it's
| probably wired as a bus, if you want to re-use that for
| ethernet, you'll want to split it up so each phone jack
| gets wired as two ethernet jacks; one in each direction. If

| switch, and you'll want to be careful to buy 10/100
| switches if you've only got two pair as Ethernet
| autonegotiation can easily do the wrong thing and you don't
| want to pay for managed switches in each room. If there's
| no ethernet use in a room, still wire it up for two ports,
| but put a small patch cable between the two.
|
| If you've got star topology phone wiring, there's a better
| chance of cat5 cabling and 4-pair and you can run gigE.
| GigE will sometimes run on cat3 for small distances too
| though. The only question is if the central location where
| the star wires meet is convenient for a switch. In a pinch,
| you can use a PoE powered switch and power it from one of
| the other ends of the star.
|
| Of course, some houses are a mix of star and bus or
| generally some form of tree. Anywhere that there's a
| branch, you want to put one ethernet port for each
| direction. And hopefully all the branches are accessible.
|
| There's really no need for DSL equipment in your own home,
| unless you've only got one pair wiring.

| Well, 100BASE-TX will also run on single pair in half-
| duplex mode.
|
| Alternatively you can also use powerline adapters over
| any cabling (twisted pair/coax/whatever). Just instead of
| connecting adapter prongs to power socket, connect to

| I mean, kind of, but I don't know how you get network
| cards to run on a single pair? I'm actually interested,

| for 10BaseT, and I've got 10BaseT half duplex device I'd
| like to network, but only one pair available (there's a
| 3-pair cable run, but two are used for voice
| communication). I've tried a commercial product (ETSLAN
| Monoline Balun), but while I can get it to work a bit
| when testing on parts of the line, it doesn't work across
| the whole line; if I can just wire something more simple,
| that'd be worth a try too.
