What else can I try?

Laptop cannot connect to internet or ping anything other than itself over it's wireless connection.  Everything works fine on ethernet connection however - can ping self, router, and get out to internet in browser.

Ping results when pinging router over wireless (see below).  #2 of 4 pings goes to local machine ('self'') with note 'destination not reachable'.  I've never seen this happen on any other machine.

Steps I've taken so far:
uninstalled wireless driver and deleted it in that step.  Reboot, allow Vista Home to reinstall the driver.  Outcome still the same - unable to ping anything except self.
Disabled windows firewall.
Disabled all antivirus/firewall software
In command prompt window - reset IP stack

The router IP is 192.168.0.1
The laptop IP is 192.168.0.27

HI

Disconnect the Ethernet cable.

Now make sure wifi is connected to the access point.  Now Ping.   It will work.

Also make sure wifi adapter is installed right in the device manager.

Then connect to the wifi signal.
Then ping.

All that says is the wireless interface is unable to ping the router, it is not trying to ping itself.

Unfortunately however I don't have a good answer to your question, just wanted to clear up some confusion.

I guess I do have something else to add.  Everything on the client side looks good from what you posted.  I would look through your router/config options to make sure nothing is being disabled/denied for wireless LAN clients.

A few notes here to QCR_Solutions and Papertrip:

Ethernet cable is unplugged.  See IPCONFIG paste in orig post. 'media disconnected'

Network And Sharing Center shows wireless as 'identifying', then 'unidentified' with Local access only.

I've tried connecting to two other routers that have previously worked, but this laptop's wireless also fails with them now too.

I going to try an external USB adapter next to see if a totally different driver will work.

I have looked at the HOSTS file, but I expect that if there was a problem there, it would affect the ethernet connection as well (which is still working fine).

If you are hooking up the wireless to other routers that are KNOWN to work as expected with wireless clients, then it sounds like a driver issue or just failed hardware.  Need to grab another wireless nic and try it on that same machine.

I will hook up a usb nic shortly, and post results.  Going to store now.

Ok, I bought a Azio 111N 150 Micro USB adapter that works fine.  $19 and worth every penny considering it is a quick workaround that took all of 15 mins to install.  Saved myself further headache going this route, though it was not as satisfactory as uncovering the real underlying problem.

Conclusion is tough to call because I still believe it's software related, though I cannot prove that.

One thing that this laptop had installed just prior to the wireless failure was an AT&T mobile broadband USB adapter.  That adapter worked, but once it was 'uninstalled', wireless no longer worked.  Though the AT&T software had been uninstalled, two services remain installed (set to Manual).

Awarding points to Papertrip for the effort.  Thank you Papertrip for trying.

See my notes above about workaround solution to this problem.  Underlying issue never discovered, though driver and/or left over AT&T services suspected.
