AP_devices_connected=$(/usr/bin/snmpwalk -v 2c -c $community $hostname .1.3.6.1.4.1.14823.2.3.3.1.2.4.1.4 | grep ${all_ips[i]} | wc -l)
Can you please consider whether
${all_ips[i]}
should be
${all_ips[i]}$
to ensure that it matches up to the end of the line. Otherwise it may match any IP address starting with the given string.

Thank you for sharing a great plug-in.
