This is one for the FAQ. :)

Linking 2 PCs using RJ45 merely requires a crossover cable (get a hub-hub
cable from your friendly network-savvy PC shop, or DIY using pinouts
available all over the web, including at

I've never seen a BNC to RJ45 transceiver (if they exist), a cheap hub does the
same job (providing they have a BNC connecter that is ;)

BNC is good and cheap, but 100Mbps networks use RJ45 - the speed is worth it.

I have 3 clones and a Vaio similarly connected. The Vaio has a cheap
Trust (brand) PCMCIA card, cost about �40 maybe, complete with BNC /
RJ45 adaptor. I slot it into the network at work and can move hundreds
of MB about.

Once you've deleted rogue devices here, Windows *should* find them
again after a restart, prompting you for drivers possibly, and
hopefully sorting everything out.

If drivers can't be found, browsing to windows\system and the like can
often keep it happy.

Given the choice of forking out for a hub thingy and changing all the
cables or getting a transceiver thingy, is the extra speed worth the
extra investment?

Your existing LAN is coaxial, this is the cheapest form of 10mbps
networking.  Your new card is RJ45 only.  You can purchase a transceiver
at a cost but it works out cheaper to buy a cheap hub with a BNC port on
it.  Connect BNC LAN to BNC port, connect UTP cable (that's the RJ45
stuff) to the hub and there you go.  Even better ditch coax altogether
and have a more reliable network.  I intend to do this at some time in
the near future.

No, just attach the hub between a node on your existing LAN and your
RJ45 network card.  All network packets will be sent between the two
media formats transparently.  It's brilliant stuff.

Depends what you or your other users are doing (the bandwidth is shared
on a non-switched hub), & maybe not if you/your users are not shunting
lots of data around but for ghosting (for instance) even with a very
basic (non switching) 100baseT hub that won't do duplex I'm getting
almost 100mbits per sec. Non 100baseT switching hubs are relatively
cheap

The big advantage of 3com cards is most operating systems 'come' with
built in drivers for almost all cards (right back as far as WFWG)

Though you can usually install updated drivers (with extra features)
from a floppy or from the 3com site.
I had a problem installing later drivers on top of the existing ones. If
you are tempted to do this, I think its better to remove the old driver
*before* installing the new ones. YMMV. Read the readme on the last disk
(usually)

I agree it sounds like software.

I had the same problem when re-installing a 'Digital VP725 or 735'
here. It just crashed when certain cards were inserted. The solution
was removing an 'Unknown Device' from the device list. Seems it was
clashing.

I'm not saying it's the same problem, just that the drivers can easily
cause this kind of problem!

They do exist; they're called "media converters" and are more 
expensive than the cheaper hubs.

Yes; a cheap hub with one BNC connector and perhaps 4 RJ45s. This has 
another advantage over a media converter: you can plug in another 3 
RJ45 workstations or printers.

If you want to use 100Mbps you have to use more expensive network 
interfaces and hubs which support the higher speed.

I've got one in the cupboard, don't use it any more though.
