Well I finally received the DSL modem 8D I plugged it to the ass of my OpenBSD server and had to put all the 4 computers of the house on the same network. Since my room is downstairs near the garage and all the rest of the house is upstairs the problem was how to wire all this altogether. I tried 56kbps wifi in ad-hoc mode (no concentrator), but heck, even though the 2 ends of the link are almost at the vertical of each other, it doesn't work well at all, sometimes the link can't even be established, sometimes the pings time out, that much that it's almost unusable. I tried this for 2-3 days and I had to give up with this method. For me wifi = crap. I wonder how commercials manage to hype and sell stuff that does not work.
Now the good thing is that I discovered Power Line Networking adapters

It's sort of little boxes you plug on the power line with a RJ45 adapter from your existing network at the end, and it's the power lines circuit of your house that do the networking. And boy, that rocks

It can go up to 20Mb or so, no more wires, no more hub/switch, and TOTAL TRANSPARENCY. You plug your RJ45 into the power socket and you have the home network everywhere where there's a power plug. €99 for 2 adapters. And that technology is expected to evolve a lot in a near future.
Just wanted to share my experience. Forget about wifi, bluetooth and all that wireless crap. PLN simply rocks
