I just found a chart that shows TW coax (RG58) at 1.1 db/M attenuation
at 1800GHz. (it's worse at 2.4GHz) That's 200 db down from about 200
mw. I don't think it'll work

1800Ghz? AWSOME! Infrared over coax!

The only problem, is the cable tends to run a bit warm. ;-)

It's 50ohm cable used for ethernet. Before 10baseT came out, 90% of
ethernet ran over rg-58

That's also true.

I want to use the existing coaxial connections in my house that is for
cable tv for my ethernet LAN.

Basically I would like to use a connection from my fast ethernet
switch, cat 5, somehow connect it to the coaxial cable that was built
into my house for tv. Then at the other end of the tv cable in a
specific room convert back to cat 5 ethernet into another fast ethernet
switch.

I tried wireless, but there is too much signal loss. The coaxial cable
is not being used from my server room to the upstairs room I want to
connect.

You might try connecting a wire from the center conductor of the
coax and wrapping it around wireless devices at both ends.

The loss in the cable will be high, but it should be less than
through walls and such. You probably don't want to actually
connect it to the antenna terminals, if any, but just wrap it
around the device.
