Your script shouldn't create output from a background process. When booting, output is piped through a logging process, and when that exits, the next output will abort your process. nohup doesn't help, it only redirects terminal output. Ideally you should not print anything directly in a background process but write a log file (or use logger / syslog). To avoid any accidential problem, you should also redirect all three standard handles (e.g. to /dev/null). N.B. the connectivity check is a bit sensitive. I suggest to probe with more than 1 packet and to also set a deadline (-w) which allows for one extra second, e.g. ping -n -c 3 -w 4.
