Windows is saying “Limited or no connectivity”. Why?
Windows is telling you that it can’t understand or talk to the modem. This can be due either to a faulty modem or a problem on the computer itself. Try power cycling your modem and rebooting your computer to see if this fixes the problem.
It may also be a good idea (for windows users) to check their network connections and try and repair their connection. This can be done by clicking on Start -> Control Panel -> Network Connections -> Right-click on Local Area Connection -> Status tab -> Repair.
If you’re able to, try another computer as this can sometimes be caused by a problem with the computers network device or network configuration
If you continue to receive this error, your modem/router could be faulty. Please contact your device manufacturer to see if there is anything they can do. They might suggest that you factory reset the modem or manually set an IP address to try communicating with it.
