I have seen several posts now with variations of this
problem for XP Pro SP2. I have a STANDALONE PC that
successfully connects to the Internet via an 802.11g
wireless router using a wired LAN card having an
automatically assigned IP address of the form 192.168.2.x
from the router.
I have installed the drivers for a 802.11g wireless PC
card, which actually connects to the wireless router, but
is unable to acquire an automatically assigned IP address.
Symptoms
1. I get "little/no connectivity" error; the card is
assigned an IP address of the form 169.254.x.x, but no
default gateway, DHCP Server, DNS Servers or leases.
2. I can ping 127.0.0.1 (loopback), but cannot ping
anything else, including the wireless router at
192.168.2.1.
3. Initially, I could ipconfig/release, but not
ipconfig/renew (repair also failed). Tried "netsh
winsock reset catalog" and reinstalled TCP/IP drivers
after deleting winsock & winsock2 keys from registry,
each of which did nothing. Finally used winsockxpfix.exe
to reset TCP/IP drivers -- now, ipconfig/renew does NOT
fail, but returns a host "unreachable" type error.
4. After all of the changes above, the wired LAN
connection still works. After applying the
winsockxpfix.exe utility, I can now disconnect and
reconnect the wired LAN card to the wireless router
without having to reboot (had to reboot before this).
5. I have two other NETWORKED PCs on XP Pro (one with
SP2 and one with SP1+various fixes) that routinely
connect wirelessly using WPA security to this same
802.11g wireless router.
Please help.
