Try networking configuration and set a restore time (tested on Ubuntu)

trynetconf.sh

#/bin/sh

RESTART="/etc/init.d/networking restart"
FILEPATH="/etc/network/interfaces"
BACKUPPATH="$FILEPATH.BAK"
RESET_TIME="now + ${1:-5min}"

sudo cp -fp $FILEPATH $BACKUPPATH && \
sudoedit $FILEPATH && \
sudo bash -c "echo 'cp -fp $BACKUPPATH $FILEPATH && $RESTART' | at $RESET_TIME" && \
sudo $RESTART

Usage:

$ chmod a+x ./trynetconf
$ ./trynetconf.sh 1min
$ trynetconf 1min

System integration:

$ mv trynetconf.sh /usr/local/bin/trynetconf
$ chmod a+x /usr/local/bin/trynetconf
$ trynetconf 1min
