XP Home Edition & DHCP

I have a similar problem to this, did you ever find a
solution?

I have XP Home Edition with SP1 installed and my computer
is hooked to a linksys router which is then connected to a
cablemodem. Typical home setup. And it used to work just
fine before I made the mistake of runnning the network
setup wizard. After that I am unable to obtain an IP
address from the router via DHCP. Even when I assign
myself a static 192.168.0.X address, mark the router as
the gateway, and use hardwired DNS addresses it will not
work. I can ping the router and the other system on my
home network. I can ping the external DNS servers. I can't
bring up the admin page of the router on my web browser.

Now, I have my C partition replicated on my second drive
(made the backup a couple of months ago) and I can
actually select to boot that at startup time. The network
comes up just fine with that so I know its mot any kind of
hardware problem. I can't see anything to adjust that
might solve this problem, the settings appear to be the
same with both the working and the broken boot instances.
I've run netdiag and netsh, no joy. What did this stinking
network setup wizard do to me? I've even tried running it
again in different ways but nothing works.
