well, the conventional wisdom is use a module to parse HTML and I was tempted to make that comment first time around. However the regex seemed sufficiently trivial that it didn't seem really to matter. Using something like HTML::TreeBuilder would sure make it easier to dig the data out for a lot of modems though - mine (which uses a table) for a start!

If you are going to use /x then take advantage of it and use some white space to break up the different components of the regex so they are easier to parse by eye. Consider:

$content =~ m{
    Frequency(\d+\s Hz)\s
    Signal \s To \s Noise \s Ratio([\d.]+ \s dB)\s
    Power \s Level([\d.-]+ \s dBmV)
    }xi or My_Die('content failed!');
