Question about IBM ThinkPad R51 Notebook

Laptop can't aquire IP address

My laptop connects to my wireless network at university, but will not connect to the network at home. I have tried repairing the network connection,but it still says signal strength excellent and is aquiring IP address. I have tried setting the IP address instead of it aquiring automatically- this seems to connect for a few seconds and then disconnects again. I have a different laptop which connects to the wireless network fine. When my laptop is aquiring the address automatically and I do run, cmd, ipconfig/all it states:

IP Address. . . . . . . . . . . . : 0.0.0.0
Subnet Mask . . . . . . . . . . . : 0.0.0.0
Default Gateway . . . . . . . . . :
DHCP Server . . . . . . . . . . . : 255.255.255.255

I have looked at the DCHP client and it is started and set to run automatically.
My laptop is an IBM Thinkpad model R51 and we have a Netgear router.
Any suggestions would be appreciated.
Thanks

    sometimes it works and sometimes it gets stuck. It can "see" the wireless network and gets stuck in a loop trying to obtain an IP address. When I press the button to identify available wireless networks it can't "see" any. The wireless symbol on the laptop case is lit up. "sees" a 54 mb network. Can connect directly on an ethernet cable. Restarting sometimes works, but not sure if that is the cuprit. Looked through MS CONFIG to see if anything had been accidentally turned off. No luck there.
    Any thoughts?

This sounds to be a compatibility issue with either the wireless software or wireless card. Check to see if there are any updated drivers for the wireless card at IBM's support site. If there aren't any or the card still doesn't work after the updated drivers are installed, then you might try a different/newer internal wireless card, or a universal external wireless card for use with your home system.

I had the same problem, went to Microsoft and found this solution on line.
1. Click Start, click Run, type %SystemRoot%\system32\services.msc /s then click ok.
2. Double-click Wireless Zero Configuration.
3. In the Startup type list, click Automatic (if it shows Automatic already, change it, then put it back to Automatic, that will activate the Apply button) then click apply.
4. In the service status area, click Start, and then click OK.

That fixed it for me after fighting it for about a month.

Setup


If that is the report that the laptop gives for an IP address, then you have to change the IP address settings.
Go into your network settings, and tell it to automatically aquire an address, and DNS.
Once you click OK, it should sense the DCHP from the router.
If the IP is already set to automatically aquire, then the router needs to be reset to factory defaults. That should put you back to the 192.168.2.xxx settings.
