OK, here is what I have so far:  (Requires m0n0-shellpack)

<shellcmd>while /bin/sleep 120; do if [ "`/usr/bin/grep -ca "xmit 
failed" /var/log/system.log`" -gt 20 ]; then /sbin/reboot; fi; if test 
"`/sbin/ping -nqc2 63.192.118.1 | /usr/bin/grep "packets" | 
/usr/bin/sed "s/.*,.*, \(.*\)/\1/"`" = "100% packet loss"; then 
/sbin/reboot; fi; done</shellcmd>

I found out a few things about this shell command and m0n0wall.

1. I can't format the script with line breaks.  m0n0 stops at line 
breaks.
2. I can't figure out how to put it into the background.  When I use 
"&" at the end it really messes things up (xml parse error/crash).  
&amp; at the end doesn't do anything.

It seems to work OK though.  Every few minutes it will test the log 
files and ping the router.  If either fail then it will reboot the box. 
  I can boot it up, surf a bit, pull the antenna off and wait 120 sec 
and it will reboot the box.  So it seems to be working.  I still need 
to test it with the xmit errors though.  I have a similar script that 
runs on my router to detect the xmit errors and page me.

I should write an extension that is configurable from the GUI to do 
this stuff.  Maybe a shell script that can be saved in the config.xml 
file.
