Debian installer hangs on network hardware detection due to Broadcom wlan chip

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=681656

The work around is to go to a different shell: Press Alt-F2 type: nano /bin/check-missing-firmware

Under the first line of the script, add exit 0:

#!/bin/bash
exit 0

Press Alt-F1 and return to the frozen screen and hit CTRL-C to kill and restart that script. Do not select the conflicting harder for network setup, and you are good to go for now!
