Public bug reported:
I installed Ubuntu 12.04.1 64-bit (Precise Pangolin) using the minimal
ISO (mini.iso). During installation, debian-installer asked for my
wireless networking information and successfully used it to connect
wirelessly to the network. It also wrote my wireless networking
information to /etc/network/interfaces. However, the WPA key that I
entered contained at least one special character, and debian-installer
did not escape or quote the special character(s) in
/etc/network/interfaces. The result was that, on reboot, the system hung
for a very long time during the boot process as it tried
(unsuccessfully) to re-connect to the wireless network. I fixed the
problem by simply quoting the WPA key listed in /etc/network/interfaces.
This should happen automatically if the key contains special characters.
Example:
Originally, the relevant part of /etc/network/interfaces reads something
like this:
auto wlan0
iface wlan0 inet dhcp
wpa-ssid SSIDHere
wpa-psk KeyWith$pecialCharacters
It ought to have read something like this:
auto wlan0
iface wlan0 inet dhcp
wpa-ssid SSIDHere
wpa-psk "KeyWith$pecialCharacters"
It might also be that the SSID should be quoted/escaped, too, but I'm
not sure about that.
