Help!

Hello,

I have a Linksys Wireless G router and 2 XP computers that were
working fine.

I am using it wired - no wireless being used.

Now one get an error that is there is low network connectivity and
cannot connect to anything.

The other computer - fine. So X - no connection, Y - connected

I tried swapping cables - same situation (different ends, new cable,
the one from Y) - X no network, Y is fine. Switched router ports -
same situation X-no, Y - yes

Plugged in modem directly into X - works FINE.

I did check the security center in the control panels - in both cases
the fire wall is on, but the windows firewall is off. I cannot
disable the firewall from X - it must be the router firewall (I tried
removing any filtering from the router - same issue). Again, Y works
fine.


Only when going through the router does this cause a problem.

Direct connection is fine.

To top it off, when computer X is booted up in safe mode and going
through the router - it is fine. An IP address is taken. In regular
mode the computer boots up and shows an IP address of 169.254.x.x. I
tried power cycling the mode, router, both, reboots - same issue
169.254.x.x. I tried hard coding the IP address to the one found on
the router and in the range of the router - no dice.

Why can't I get an IP address from DHCP?

Computer X does not Norton Antivirus on it - I disabled it in regular
mode - same problem. I do not want to uninstall it.

I read about a Service Pack 2 problem with XP - but the problem does
not appear in Safe Mode with Networking and I did try the fixes my MS
about it - to no avail. The underlying issue is that computer X
cannot get an IP address from the router.

Computer X work when:
- there is a direct connection from the modem (DSL) to the computer
in regular mode
- booted up in Safe Mode and attached to the router - can ping it,
surf the net

Computer Y is fine with the Router.

Suggestions on how to proceed?

Help!

Thanks!
