The modem shows that it is online and working within specification.
May we ask for you to clarify the exact issue? You've advised that the service works on your computer, but you've claimed that the modem is not working or won't work?
Is the computer connected via Ethernet cable to the modem? Please provide more information for us to analyze the case.
