Unable to get an IP Address from Router.

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!

Tmuldoon,
Have you made sure that your "Windows" Firewall is turned "OFF". The
routher has its own firewall. You can not have Windows firewall on at the
same time.

Hello,

Yes, I made sure it was off.

However the OS says a firewall is one. Norton is installed - but
there is no firewall option.

I killed all tasks associated with Norton - and still the same
problem.

Yet it works in Safe Mode. I can renew and release and IP in that
mode. Not in regular mode.

Very curious.
