  • IMPORTANT: You need Windows PowerShell to run this command - in your Windows Command Prompt, type powershell Create a log file of your Motorola Surfboard SB6141 downstream signal strengths. Uses the built-in curl to request signal strength data from your SB6141 cable modem. HTML page 192.168.100.1/cmSignalData.htm has the signal strength numbers for the 8 downstreams. Some HTML/DOM processing parses out the 8 values from the above page. The eight extracted signal strengths are then logged to a file. A small while-loop watches the clock & repeats the process every 10 seconds. Show Sample Output

    while(1){while((date -f ss)%10-gt0){sleep -m 300} echo "$(date -u %s) $((curl 192.168.100.1/cmSignalData.htm).parsedhtml.body.childnodes.item(1).firstchild.firstchild.childnodes.item(5).outertext|%{$_ -replace '\D+\n',''})">>modemlog.txt;sleep 1;echo .}
