Public bug reported:

Binary package hint: network-manager

Ubuntu 11.04, fully updated
Atheros Ethernet card and Broadcom BCM 4313 wireless card, on Dell Inspiron 
N7010
Freshly installed system

The problem is that both wireless and wired connection do not work. This is 
unless either one of two things is done:
1. UTP cable was plugged in before system starts
2. Uncheck enable wireless before restart and then enabling it when everything 
has loaded again

If I plug in UTP cable after system has been fully loaded, nothing will
happen and I will not have internet connection, not even wired one.

Broadcom STA drivers are enabled and since they work when steps 1. or 2.
are taken, probably means that the issue is somewhere in network
manager.
