I was wondering what the signal really does at the cable modem, so I’m scraping it with perl and WWW::Curl::Easy
Motorola Surfboard SB5101
All I’m doing is grabbing the signal status page from the modem and pulling out the signal quality data using perl.
If you have this page, you’re probably good – http://192.168.100.1/RgSignal.asp
Just rename the download, adjust the line endings, if needed, change the logging file, and set up a cron job to run however often you’re interested. The output is tab separated text file, perfect for importing into Excel.
