what happens when you run this from the command line?

If you are using bash try changing the file to:
Code:
#!/bin/bash
route add default gw 192.168.1.1
Try changing the crontab entry to:
Code:
0 * * * * /home/mad/gateway >/tmp/output 2>&1
Then check the output file for any clues to whats going wrong.

I am assuming that the user for the crontab is the same user that you tested the script.

cron has a minimal default env, specifically the PATH variable.
Always specify the entire/absolute path to any prg or data file if called from within the cron env.
eg
/sbin/route

Why would you need to update your default route or gateway that often? It shouldn't change at all unless you have another process changing it which seems sort of odd.
