Description of problem:
  After upgrading using preupgrade from Fedora 13 to 14 NetworkManager seems to not set the default route throught the gateway after connecting to wifi (brings up wlan interface and it gets the ip via dhcp), DNS resolution works but since default route is not set you can't access anything outside your lan and you get a "connect: Network is unreachable" message for every connection attempt.

Version-Release number of selected component (if applicable):
  NetworkManager-0.8.1-10.git20100831.fc14.i686

How reproducible:
  Every time NetworkManager (re)connects to wifi.

Steps to Reproduce:
1. Log into your machine
2. Let NetworkManager connect
3. Try to access any internet address (gmail, google, anything like that ...) or use any console app to connnect, you will get a "connect: Network is unreachable".
  
Actual results:
  Applications can't connect to ip addresses outside local lan

Expected results:
  Applications can connect to ip addresses outside local lan

Additional info:
  Using command "ip route" I saw that default routing was missing, so as a workaround I set it by hand every time NetworkManager connects or reconnects to wifi with "ip route add default via 192.168.0.1".
