I know it sounds like a bit of a hack, but I was having this problem a
few years back and wrote a shell script that would ping three expectedly
high availability websites (google, yahoo and another i can't remember).
If all of the three were unavailable, then the script would use the
router's web interface to reboot it.
Now it's not ideal, since you've got to have the router's password
stored in the script, but it worked. Unfortunately I no longer have a
copy of the script, but it shouldn't be too hard to cobble one together.
Certainly cheaper than buying a new router.
