Public bug reported:
Binary package hint: network-manager
I previously configured our Lucid workstation on Static IP, however,
recent company policy changes forced me to use 2 network connections.
Here's the current company setup:
The gateway/router supplying our wired connection with IP Address
192.168.13.1 has been physically disconnected. All wired workstations
are configured for Static IP Address. A wireless router has been setup
and the gateway plugged in with IP Address 192.168.13.1. Thus, all wired
connections can only access servers and workstations on LAN. To be able
to access the Internet, you need to connect via Wireless. MAC and Static
IP Address has to match and registered before being able to connect to
the Internet. Unregistered MAC and/or mismatched IP Address would allow
you to connect wirelessly, but won't allow you to access the Internet.
Both Wired and Wireless Connections are configured with Static IP

But this is unrelated to the bug I'm reporting, I'm just giving you guys
a background so you have an idea why I have one wired and one wireless
connection.
So:
Wired Connection: access LAN Servers
Wireless Connection: access Internet
Obviously:
Wired Connected, Wireless Disconnected: can't access Internet but can access
LAN Servers
Wired Disconnected, Wireless Connected: can access Internet but can't access
LAN Servers
The Bug:
Wired Connected AND Wireless Connected: can't access Internet but can access
LAN Servers
Note: this is possibly due to Bug #629284 fixes
The Workaround:
I right-click nm-applet and uncheck Enable Networking
wait for 5 seconds
I right-click nm-applet and check Enable Networking
I Disconnect Wired Network
I Connect to Wireless Network
verify that I can access both Wired and Wireless connection
Note: this workaround is 'technically' another bug!
What I Need:
I need to access both LAN Servers via Wired Connection and the Internet via
Wireless Connection
