[PROBLEM] Losing wifi at power glitch

Anyway here's the function.

Code:

function waitForIpAddr($iface, $maxloops = 3, $sleeptime = 3000000) {
    for ($i = 0; $i < $maxloops; $i++) {
        $ipaddr = sysCmd('ip addr list ' . $iface . " | grep \"inet \" |cut -d' ' -f6|cut -d/ -f1");
        if (!empty($ipaddr[0])) {
            break;
        }
        else {
            workerLog('worker: ' . $iface .' wait '. $i . ' for IP address');
            usleep($sleeptime);
        }
    }

    return $ipaddr;
}

 Where would you insert this function?
