My desktop PC can't connect to the internet

[Microraptor13]

It is connected via Ethernet and is using Windows 10. It is about 6 years old, and I don't know the exact specs of it at the moment.
The Ethernet connection works (I tried it with my Laptop) but my desktop continues to say it is connected to an Unidentified Network with no internet access.
I tried ipconfig and it was filled out except for Connection-specific DNS Suffix
Any ideas as to how this happened and how to fix it?
I haven't used it for about 5 months.

First, try restarting the router & the PC with full power off on both.
Restart the PC first and login.
Then power on the Router and see if there's a change.

Second, change the network to PUBLIC;
Control Panel->Network & Sharing
On the left panel you will see your network name and classified as
Home network -- click this and change to Public

disconnect the ethernet cable to the PC, wait 30 seconds and then reinsert it. What's your status?

After doing all of this, it said Identifying for a few minutes, then returned to saying Unidentified Network.

What Make/Model is your router? Any Idea how old it might be?

I don't, sorry. It did start working after manually setting the IP address and DNS.

That says the router is having problems with the DHCP request to your ISP.

*IF* you had the make/model of the router, then we could look for an update for the firmware.
