OpenWrt routing in relay mode to detect restart scripts

Home routing relay Others distant a tp-link to the Internet, but the distance is too far, often disconnected, the disconnection is not aware of the abnormal, so write a test script to determine whether to drop the line

Mainly ping Superior routing

Through the ping 114dns did not touch the shell script, the logic is not how to do well directly up a while cycle plus multiple if

It's a bad writing.
