This message occurs when your NIC is set to obtain an IP address
automatically but is not receiving an address from a DHCP server.
(You can check this by running ipconfig /all from a Command Prompt
window. You should see (about the 4th line down under your NIC's name)
"Dhcp Enabled: Yes" and the IP Address will be of the form 169.254.x.y)
In a wireless network, the usual cause is that the client (your
computer) has not properly authenticated to the access point (your
router) because of a security error. Eliminate this possibility by
(temporarily) removing *all* wireless security (encryption, MAC filters,
IP filters, etc.) using your router's configuration utility. While
you're in your router's configuration utility, double check that its
DHCP server is, in fact, on and set to allocate enough IP addresses to
accommodate your LAN. Go back and delete the entry for your network
from the list of preferred networks, because it will have a saved
password and thus won't connect to the now-unsecured wireless router.
If you still can't get a working connection, MVP Chuck has a page that
is a good starting point to continue your diagnosis:
http://networking.nitecruzr.net/2005/07/limited-or-no-connectivity.html
Given that you ran into this problem when you uninstalled things, I
would suspect an LSP/Winsock problem. See the link on Chuck's page
linked above for multiple suggestions on this, but for your first try,
I'd suggest:
netsh winsock reset catalog
from a Command Prompt window.
