router assigns IP address but no gateway

This is driving me crazy, I am sure there is an easy explanation but I can't
find it. Sorry to post here but there isn't any group I can find for
Windows2000 in older versions and I figured XP is probably the closest. So..

Friend asked me to help with son's computerthat was working fine hooked up
wirelessly to Zyxel router but stopped. Linksys USB adapter found router, IP
address assigned, no gateway. Four other computers are using router
wired/wirelessly with no problem.

So I reinstalled wireless adapter, then changed wireless adapter to another
brand, again same thing, no gateway.

Tried to do a wired LAN, same thing, no gateway. Tried fixing IP stack,
static IP, manually configuring gateway, reserved IP on router by MAC
address. The router sees the network adapter in every case so it must be the
computer. It is running Windows 2000.

No firewalls, can't ping router altho it connected to it because it gave it
an IP address and shows up in the dhcp table on the router.

This is driving me crazy, why doesn't it assign the gateway! Any ideas? I am
sure it is obvious but I have run out of ideas. Any help would be
appreciated. Am I missing some protocol? But it was working before.

What does the routing table say?
route print > temp.txt
(then post temp.txt here)

I'll go back over and do that, but where do I run that, in a cmd line?

The router correctly identifies the machine, I can tell by the MAC address
of the NIC and the IP address is in the DHCP pool range. Just no gateway.

Thanks for your help

Hi
Giving what you already did try to reinstall Windows 2000.
My guess would be that Internet surfing trashed network related parts of the
OS that need reinstall.

What antivirus does the computer have?

If Norton, there's your answer, most likely.

If not, and it gets an IP but no gateway, then it seems likely that the
router's DHCP is playing up. It might be that the router isn't set to
advertise its own IP as the gateway.

BTW, if the IP it 'acquires' starts with 169. then it HASN'T got an IP, this
is the fallback when DHCP has failed to work. Most routers use 192.x or 10.x

What IP address does this PC get? Is it supposed to be the IP address
"style" that the router is "giving" out? The PC might be getting a
"signal" but does not completely get an IP address so it maight
default to the "auto IP feature" that MS placed into XP.

Yes.

You might also try adding the default route from a command line also
using the route command.
Example: route add 0.0.0.0 mask 0.0.0.0 192.168.1.1 metric 1
(if the gateway is at 192.168.1.1)
