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.

wlancfg
WLANCFG(8) System Manager's Manual WLANCFG(8)
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.
