Is there such a thing?

Basically I want to connect a PC upstairs via ethernet to my router in the basement (wifi signal is weak thru two floors and basement metallic roof).

I do have a coax (regular 75ohm) cable running end to end. Is there an adapter out there that I can stick on both ends and use as ethernet?

Thx.
 
I'm fairly certain that no such device exists. A cat5 cable and a coax cable are radically different in design.

I could be wrong though.

You can do it through the power, assuming you don't have surgeprotectors... not sure how much the adapters are, but I've used 'em before.

Basically the adapter plugs into the wall outlet, and has an ethernet outlet on it, for both sides.

Yep. MaximumPC tested 2 this month... Netgear was much faster.. Basically the only one that works worth a crap at all.
 
Back in the day there was something called token ring that used coax, but finding parts for it today would be hard as hell I assume.
 
Heh token ring, remember seeing those on those ooold NICs.

Crap, looks like might have to pay someone to fish a cable or two through, the power ones seem expensive (and too new for me to trust just yet).

The power ones have been available since 2000 (HomePlug 1.0), its the newest Netgear ones supporting 200mbit which are really 'new', even the last versions (HomePlug 2.0 claim to do about 85mbit (about 40ish usable).

Another option is a few firms have kits for sending wireless signals over coax. The idea being you put the access point at the cable headend and little antennas in each room for better coverage. Would reliably extend your wifi down over the coax. I think smarthome.com sells them.

i've got a coaxial nic somewhere around here. i think it was ethernet. at least, that is what the driver disk said on it. don't think it passed the token.

For some reason the phrase "are you going to hit that or what?" just popped into my head.

hey PM me if you're interested in a Netgear power over ethernet set (plus a netgear router)... I got them laying around before I picked up wifi, I had trouble with the signal in my house, maybe you'd be better off.
then again, they are HomePlug 1.0 IIRC, so they get about wifi b speeds in practice.

Yes you are wrong. And this thread is in the wrong forum. It should belong in the networking section.

Can you link to the adapter that will allow him to connect his PC upstairs to his router downstairs?
 
this is like is there an AGP to PCI card? yes, but it was so uncommon, nobody ever thought it existed.

were there cd-writers? yes, they released some 2x models in the late 90's to consumers, at very pricey ratios. worth it or not, I don't know, but the 4x external models were so bugged to the point that I just waited for the 40x models that came out for a little over a hundred bucks. I was satisfied when I stuck it into my AMD K6-2. as slow as it was, it burned VCD's in under 30 minutets, so me and my friend were happy.

yeah, it exists, but it's not common enough where someone would offer you the model and specification of how well would perform. usually this would be a 90's enterprise solution for outdated 3.1 computers that needed test runs (for example) as most business were switching to PCI (from ISA) add ons that boasted the flawless 10/100 ethernet connection.
 
Why not put a omni-directional antenna on your router and a directional antenna on your pc? I've seen some homemade ones in the past on this forum.
 
I'm glad someone said it before me. (10base2). Though that used 50 ohm cable, instead of 75 ohm cable. Used a bus architecture vice the star that cat 5 uses or the ring (Token Ring).

What you are looking for are called "Coax to UTP media transceiver". These devices allowed integration of different media types. They also come with fiber, db, and other connections. They are going to be expensive.

Your best bet is to just get some CAT5, tie one end to the end of the coax, and use that as a snake.. to pull the CAT5 cable through the existing path of the coax.
