Windows 7 Wireless has limited connectivity on Verizon Hot Spot, no default gateway

I have a Sony VAIO running currently patched Windows 7 Professional, am able to connect and use any WiFi connection except the HotSpot on my Verizon Wireless cell phones (2 of them).   This used to work until the last month or so.

When I connect the VAIO to either HotSpot, it gets an IP address but no default gateway, and was set to Public because there was no gateway.  I have been able to change the connection from Public to Home, but it still shows no Internet connection.


My other devices and laptops (running Windows XP, etc) can connect through the HotSpot just fine, so I know the HotSpots function normally.

Open cmd prompt on system and do an IPCONFIG /ALL make sure the IP information for the wireless connection is correct.  IF it is and there is both a default gw and dns servers are correct, try a tracert www.yahoo.com does it resolve??  Next try remaking the wireless connection on the system disconnect go to wireless networks and remove the profile for the wireless AP, then reconnect.  If at the IPconfig there is no gw or dns listed then something has gotten missed up on the phone's DHCP, check settings and you may have to power cycle the phone by shutting down and removing battery if possible.

Also try and turn off the Windows Firewall temporarily and see if that makes a difference. If it does, you may need to add an exception rule for the Verizon Hotspot.

Windows 7's firewall is much more comprehensive than XP's was.

Thank you for the suggestions.  

The TCP/IP 4 was set to automatically receive an IP address and DNS.

Diagnosing the problem indicated that "The default gateway was not available".

(Verizon Wireless HotSpots normally do not have a default gateway.)

Shutting off the firewall had no effect on this problem.

The suggestion to run CMD as an administrator then

IPConfig /Release
IPConfig /Renew

fixed the problem, and we were able to get a default gateway from both HotSpots.

Kudos to both experts!
