You have a syntax error. The double semicolons are not needed at the end of your fi

I also don't know about your version of id, but the one installed on my version of linux accepts a -g option, but not with an additional parameter. If the return is always false, you might want to read the man page for the id command.

NAME
wlancfg - manupulate linux-wlan-ng MIB values SYNOPSIS
wlancfg query dev wlancfg show dev [all] wlancfg set dev wlancfg list wlancfg version DESCRIPTION
The wlancfg utility program provides an alternative method to wlanctl-ng (1) , for manipulating MIB values. It was designed to provide an easier mechanism for saving and restoring the complete wireless configuration (i.e. when re-starting the device driver) and to provide a more efficient mechanism for GUI's to query multiple MIB's. OPTIONS
dev The name of the device (e.g., wlan0). query Read MIB names (separated by whitespace) from stdin and output their values (separated by carriage returns) to stdout. The MIB's may be either read/write or read-only. show Query the values of all supported read/write MIB's and output their values (separated by carriage returns) to stdout. The syntax of the output will be: name=value If the "all" parameter is specified, then all supported MIB's (i.e. read-only MIB's as well) are output. set Read MIB name/value pairs (separated by carriage returns) from stdin and set the values of the specified MIB's. The pairs must have the same syntax as above. The MIB's must be read/write. list Display a list of all supported MIB's. version Display the compiled version of wlancfg. SEE ALSO
