Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

You can write a shell script checking the state of the network and/or interface, next if the network is unavailable or the interface is down or combination of both run some command in your script to connect again.
Test the script to see if it works and does what you want/need it to do and then plan it to run like every 10 minutes using cron.
But I believe it's most important to look for the underlying reason why you get disconnected and not write a solution. If the network or interface goes down on a regular basis there must be a reason for that. If you find what causes it maybe you can fix it so there will be no need for a script.
