Buy a network switch. Cost about a tenner. Plug the cable modem into one
port, PC in another, ATA in another.

Won't work I'm afraid. Cable modem will only accept packets from one MAC
address - the one it gave DHCP to. All the others will be binned - after
all, they won't have globally-routable IPs.

You'd need a router. A cheap wired-only router is about 20 quid new, or buy
one secondhand from someone upgrading to wireless. Alternatively some ATAs
have built-in routers (like the SPA3102).

Well, I have news for you, sunshine. It works just fine on Virgin Media
cable broadband, as long as you reset the modem after connecting the
switch. Did it only last week.

Unless you have the old gaming service, VM only provide a single
routable IP,

So, unless you have a router, or are using ICS etc, what you suggest
/shouldn't/ work on a VM cable connection.

One device will grab the IP, the other won't be able to access the
internet.

That's the way I would understand it. It needs a NAT to be able to
provide the local IPs. I wouldn't have thought that a simple switch
would work and that it would need a router - for example the SPA-3102.
It is a surprise to me that more than one WAN IP is issued. At least
that is how I understand what has been stated.

Well, on Monday, three of us were using it at the same time, two on WiFi
and one wired. Though it is possible that the switch was a router. It
was a spare one from my odds and ends box.

How did you manage to do Wifi without a router? The only network switches
with integrated Wifi I know of are wireless access points. You'd probably
only have one of those if you got it for a particular reason. It's more
likely to had a router in your spares box than a WAP.

One connected to the switch on the cable modem and two wirelessly
connected to a neighbour's access point.

Nope. The neighbour's AP is encrypted.

Yes, this is an AP with four ports. Cable modem in one, PC in another.
Most APs have no router in them - they're just a network switch with a
wireless hub attached. But it may have a DHCP server and a router in it
- this one is pretty old and probably cost a lot. I'll try and remember
to take a cheap switch and try it next time I'm there, but that'll be
next month.
