Can I use BNC cable for RJ45? Can I extend BNC cable?

Hi, I have an existing BNC cable hard-wired into my apartment but find BNC a
constant nightmare to diagnose faults on. I also have a new Sony Vaio which
has a built-in RJ45 socket, which would be nice to use instead of a separate
BNC PCI card. Can I use the BNC cable and modify the plugs at each end to
work with RJ45 network cards?

As a separate question, I need a bit more length on the BNC cable. Will it
cause problems to extend the BNC cable by adding a male<>female cable to the
end of the cable's existing female plug?

Thanks in advance.

No, the cables are completely incompatable. *however* you could get a
hub with both 10Base2 and 10BaseT connections and link your new
machine in that way. However a cheapo combo card will no doubt be
cheaper.

Yes, you can extend cables like that. My office was awash with linked
cables like that before we stripped it all out and put in new Cat5.

Best advice is change to cat5 wiring.

If you can pull the bnc cable freely you should be able to use it to
draw a cat5 cable through the wall -- if you do it carfully making a
nice smooth joint and have somebody feeding the cat 5 wire in as you
pull the old cable out.

No unless you want to do 8 Co-ax runs for each length of CAT5.

Hi. This is my friend, Jack Shit, and you don't know him.

The limit on length of BNC cables using ethernet is 110m from the ethernet
card to the terminator at the end of the wire segment. You cannot extend the
length of the cable beyond 110m. So long as you are less than this length,
and use proper connectors you should be oK.

Unless you've got a repeater.
I'm about to throw one out? Anyone want it before it hits the dustbin?
