I use a broadcom as well.  When doing a fresh install I connect via 
wired connection until after I can get the restricted drivers installed 
(Broadcom B43 wireless) then Network Manager works as necessary.  You 
may not have to reinstall but try going wired and checking for 
restricted drivers (System -> Administration -> Hardware Drivers) to see 
what you have active.  Disable and Re-inable your driver.  I know that 
the STA in my list caused issues so I went back to the B43.
