I have a Lenovo laptop T61 that cannot see past the router to the internet. I am running Windows Vista. The wireless internet connection works fine on another computer. The Lenovo laptop worked fine until I uninstalled the AT&T Communication manager and settings using the Windows uninstall program from the control panel. I was using this program for tethering w/ my Blackberry. I no longer need this function and simply want it to work on my wireless home network which is Comcast cable modem with a NetGear router. When I do ipconfig at the command line, it shows:

Connection-specific DNS Suffix : mshome.net
Link-local IPv6 Address : fe80::2daf:2ad2:728f:9914%9
Autoconfiguration IPv4 Address : 169.254.153.20
Subnet Mask : 255.255.0.0
Default Gateway :

Bottom line is it connects locally to the NetGear router; but, not beyond to the internet. My best guess is I clobbered some IP settings in removing the AT&T app. If I try to do "Automatically get new IP settings for the network adapter "Wireless Network Connection" from Windows Network Diagnostics, it says "Windows tried the following repair, "Automatically get new IP settings for the network adapter "Wireless Network Connection:, but it did not fix the problem." If I do the Reset the network adapter, that doesn't work either.

If I look at the ThinkVantage Access Connections, and use Tools from Advanced, I try Diagnostics. It also shows IP addresses of 169.254.153.20, 255.255.0.0, and 0.0.0.0 for default gateway, DHCP server, and nothing at all for Pimary WINS server or Secondary WINS server.

Any suggestions will be greatly appreciated.

When I boot, I get another error msg: There was a problem connecting to the TPM (security device) on this computer. It is possible that anti-virus or firewall software is blocking the connection. A missing or disabled device driver could also cause this problem. Please refer to the online documentation for more information."

Please attach a screen shot of the Networks page of the Xirrus Wi-Fi Inspector and show ...

Start, Run, CMD, OK to open a command prompt:
(For Vista or 7 type CMD in the Search box after Start)

Type the following command:

IPCONFIG /ALL

[Note that there is no space between the slash and ALL.]

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If necessary use a text file and removable media to copy the results to a computer with internet access.

How do I enable IP routing?
Enable ICS. But you ought to get a connection to at least one network first.

Make sure you have the latest wireless driver from Lenovo's web site.

(From a JohnWill post)

TCP/IP stack repair options for use with Vista or 7.

Start - All Programs - Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log

Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log

Reboot the machine.
