Is there a workaround for this?  If it is a kernel issue, shouldn't the
development team have already fixed this?

I also have the bcm4313 and the wifi failed at one of the 3 routers I
tried to connect.

  Confirmed

Bug description:

  Impact:
  Broadcom BCM4313 does not work with the proprietary driver.

  Step:
  1. Install Ubuntu 12.04.1 -proposed (kernel 3.2.0-52), and boot to desktop
  2. Try to connect to bg/n wireless network.
  3. Install the Broadcom STA wireless driver.
  4. Repeat step 2.
  5. Reboot, and repeat step 2.
