ifscheme issue in Debian Wheezy

ifscheme in Debian Wheezy appears to have startup issues.  The script may not remember the previous scheme following a reboot; the script may not even run at boot.

To work around the issue I had to change the line in /etc/init.d/ifscheme:

Start-Defaults:  1 2 3 4 5

and also add:

ifup wlan0

 within the top if statement.
