You're using wordpad aren't you?

In perl, backticks qx aka `` are used to execute a program and capture the output, observe

$ perl -e " warn `Can’t enable:` "
'Can’t' is not recognized as an internal or external command,
operable program or batch file.
Warning: something's wrong at -e line 1.

Also, self documenting variable names are better than comments

my $RouterIP;
my $RouterUsername;
my $RouterPassword;
my $RouterPasswordEnabled;
