Yes, definitely. Here is the same information for my own desktop (from which
I am actually sshing into the laptop) - not to mention that the ethernet card
on the laptop is getting both:
the laptop:
eth0 Link encap:Ethernet HWaddr 00:14:22:e7:6f:21
inet addr:192.168.0.9 Bcast:192.168.0.255 Mask:255.255.255.0

Yes. And checked and rechecked.

Ah! That could be part of the problem,but on its home network it has worked
fine for several years, and stopped working suddenly on Friday afternoon, on
the clients' premises, while connected. I had been upgrading earlier.

Indubitably.

The access point is an integral part of my modem/router, a Netgear DGND4000 .

I'm not sure what you mean by this. If you mean is my router configured to
allow access only by named MAC addresses, then yes, it is. And again, I have
checked and rechecked the MAC number of the network card on the laptop that
is sort of alive, and its entry on my router. My router also reports not
only connected wireless devices, but also those trying to connect. It is not
registering at all.

Dearly as I love my clients, no. Or anyhow, only as a last resort. I'm not
keen to risk messing up my network. Their network is IPv4 only, their ISP is
IPv4 only, their router (supplied by the ISP) will therefore be doling out
IPv4 only, I would have thought. And the reason I have the laptop here, is
that it stopped working there, having been working for years. One minute it
was connected, and the next it wasn't and I had to connect by ethernet. So
at the moment it doesn't work in the absence of IPv6 either.
Thanks for all your help.
