Wireless PC Keeps losing IP Address - Help!
 

Last week I set up a small home network between my Mac (Panther) and PC (XP) with a Linksys Wireless router and a Belkin wireless PCI in the PC.

The internet (via NTL cable modem) has been working fine but this morning the PC has lost its IP address and defaulted back to 169.XXX... However the wireless connection is still functioning and the router can still see the PC

I have the Linksys router set up to Clone to Mac address of the PC so there should be no problems.

Rebooting the XP machine seems to solve the problem. Any ideas?

as opposed to 192-168.1.101? I assume the router is left on 24/7? How about the PC. Could be that it had difficulty communicating with the router when it needed to renew its IP lease?

Exactly - The router is left on 24/7, yeah. The PC is turned off an on as necessary. Today it lost it's IP address right in the middle of browsing. Strangely it never happens on the imac.

Advice?

At the mo it's happened once. I'd wait and see if it happens again. Otherwise at the moment put it down to one of those unexplained glitches that arise.

It's actually happened twice, but I see you point. Thanks

I had a similar problem with my belkin set up, but that was on early firmware last year. A router firmware upgrade and a driver upgrade for the PC card fixed it.

The early router software ignored the DHCP lease settings, it was always something like 3 minutes whatever it was set to in the config. Open a command prompt window and try ipconfig /all to see what the lease renewal time is.

In your Wireless Network Properties, click Authentication and make sure that 'Enable IEEE 802.1x authentication for this network' is DISABLED.

See if that helps.

In addition to the other suggestions....

Have a look at this similar thread from the start of June:

Also, to stop the XP PC from reverting to an APIPA IP address (169.XXX...) when it's unable to renew the lease from the wireless router's DHCP server, have a read of this:
