bnc hub

Hi,

I'm wondering how to connect my home network to ADSL. The network is
bnc but all (?) adsl routers seem to be rj45 types. So I was thinking
about a adsl router feeding the nearest PC (for speed) and a hub,
bnc/rj45 which would then link to the other PCs. Adding rj45 cabling
would be a pain, not to mention quite expensive.

Since a 4 port router is only a bit more than an adsl modem it would
seem a good idea to get a router rather than just an adsl modem
(future proofing), plus I guess it would have more features.

But, where can you get a rj45/bnc hub? They seem a bit thin on the
ground. Also are there any problems with this scheme?

TIA

look around, my first hub was 8xRJ45x10Mb and a BNC socket, so they do
exist. You could connect the DSL router to an RJ45 socket and then link your
existing 10Base2(?) into the BNC on the side.

this might get you started...

Try a used EN108 (not EN108TP) from eBay.

I've just sold two for about £15 each - sorry none left.

If you dont want to cable, have u considered wireless?

I'm pretty sure that 3Com do BNC hubs (at least they used to). Just done a
quick search on Google and it threw up a lot of results so looks promising

I dont like using BNC anymore after having had to look after 30 computers
using BNC connectors and cable - if the cable is broken anywhere the whole
network went down till the fault could be found - sometimes quick 10 mins
sometimes longer.

I use RJ45 cable now as a cable fault causes one computer to lose its
network connection.

I agree. The cost of re-equipping with all UTP style networking gear is
less than the cost of a bag of silver plated BNC connectors

Bite the bullet, and scrap the BNC stuff. You can get connectors for
legacy systems from companies like Black Box or Betterbox tho.

Most resonable hubs have ONE BNC port on the back tho.

As an aside - it's worth keeping hold of at least one hub in the spares
cupboard. One thing you can't do as easily with a switch is run a
network packet sniffer. Hence having a hub handy to insert when you need
to do some low level diagnostics can be useful.

Cheeky sod! ;-)

OK lets spell it out:-

As I said before - yes this will work just fine. Hubs with BNCs are
harder to find and a bit more pricey than straight RJ45 only ones but
you can get them, for example:-

Well it was getting a bit Harry Enfield "You don't want to do that!
You want to do this!". And I was only meaning the posts saying
replace the bnc network.

Thanks for the link. I have seen cheaper than this though.
Apparently broadband buyer has some, but not listed on the web site.
And Novatech have one (which is a bit cheaper too).

Incidentally I asked dabs if any of their value range were bnc, I
couldn't tell since they didn't give a spec. There answer was that
they source parts from many places and so could not give a spec. Hmm!
A bit like buying flood damaged tins - without labels :-). Could be
caviar or dog food!
