Windows 10: Connection was already enabled but failed with error 651.

Well that is interesting. So basically a hardware failure somewhere else was preventing your connection. Thanks for sharing.

My ISP had already fixed the problem.
Today I plugged in the modem, and then I could access the Internet without doing any setting.
It is indeed a plug-and-play device. DHCP need not settings under Windows 10.

 

Right now, my modem's LAN port is connected to a router connected to my computer.
Is there an IP address assigned?



Without the router, the status was shown in this post Connection was already enabled but failed with error 651. - Windows 10 Forums

 

Yes your computer was assigned ip address (IPv4) 192.168.0.101.

Lots of routers hand out addresses starting at 100. There is likely something using 100, phone, printer, another computer.

Your router address and gateway are also listed 192.168.0.1.

The range between 2 and 99 are set aside so you can assign to specific things if required, like printers. Apple Airprint seems to work better with static IP's. It can also be specialized gear like heating controls where you use port forwarding and always needs a consistent address.

the range from 101 to 255 is available for general household devices and phones.

It is my phone.

 

Perfect. So it is working just as it should. Now you can connect your printer to network and or guests.

So routers have ssid's for Guests which means something they bring in will have a more difficult time get to your data.

 

I already knew that, but it did not work in my case.

 

Sorry, what didn't work.

My post #50 was a response to another member's post, which was subsequently deleted, so you can't see it.
However, you should have received an email notification of that post as I had. The member was kelvinewknjkds according to the email.

 

I try to keep current. Must have missed.
