Reverting Wireless to Wired Network.



I have a three computer home network (2 XP Pro's SP2 and 1 2000 Pro).
Originally, they were networked with thin ethernet cards, no hub and a
shared DSL broadband attached to one of the XP machines.

I "upgraded" this to a wireless network using encryption but didn't like the
frequent disconnects so I tried restoring the network to the thin ethernet
configuration. Now none of the three computers can talk to anything,
including themselves.

If I ping 127.0.0.1 all computers respond correctly but if I ping their
local IP addresses all of them time out. They all have IP address in the
169.254.x.y range and all have a status of "Limited or no connectivity". If
I force an IP address (rather than let them be automatically configured) the
status is then OK but still they can't even ping their local addresses.

I suspect something about the encryption has carried over from the wireless
setup. I note that the adapters properties have Authentication 802.1x
enabled, whatever that is. I've tried disabling that but it doesn't seem to
fix the problem.

I'm not sure if I should have a dhcp server and, if so, on which machine it
should be running. I don't see such a service running on any of the
machines, only dchp clients. Is there a way to start such a server?

Can anyone help?
