I played with script on an Intel box running Debian and made a few changes:

On a similar note it reminded me of this I'd written about a year ago.  It 
brings an interface down then up if it can't ping google once as a test. 
It would crash hard if there was some billing screwup and my phone got 
shut off.  You can change the logging location to something other than 
/usr/programs/scripts/dhcp/resets.txt and the interface name.  The real 
world problem I was seeing is that if the cell phone is trying out a 
signal from a different tower that dumps the internet temporarily.  I was 
calling this from a cron job every 10 minutes.

#!/bin/bash
declare tries=0
until  (ping -c 1 www.google.com > /dev/null) || (tries > 9) ; do
  tries++
  /sbin/ifdown wlan0
  /bin/sleep 1
  /sbin/ifup wlan0
  /bin/date >> /usr/programs/scripts/dhcp/resets.txt
  if tries > 9 ; then
    echo "\nMany retries\n" >> /usr/programs/scripts/dhcp/resets.txt ;
  fi;
done

Nothing to do with routes explcitly.

Not yet.  If I can't fix this tomorrow, I'll write another sd card
...snip

follow the below 5 steps for help solving this.

1.) highlight/copy from the NEXT line down to the line '# EOF'
#!/bin/bash
# untested, there may be bugs, ymmv

which ip || {
   echo "run 'sudo apt-get install iproute2' for needed tools"
   exit 1
}

$0.out

function out() {
   echo -e "\n#### running: ${@} ####\n"; $@ | tee -a $0.out
}

out ip a
out ip l
out ip r
out ps ax
out cat /etc/resolv.conf

for f in $(find /etc/network -type f); do
   [[ -f ${f} && "$(file "${f}")" =~ text ]] && {
        out cat "${f}"
   }
done

echo "data saved to $0.out"

# EOF

2.) paste/save that into a new text file named ck-ifaces

3.) then in terminal as root, run:

you@box:~# sh /path/to/ck-ifaces

4.) post 'contents' of ck-ifaces.out to pastebin.com (not here on list)

5.) post 'link' to your pastbin data here
