Unidentified Network on Ethernet Connection

I have been trying to fix a recurring ethernet issue that sometimes appears.
As of yesterday it was working fine, I had a stable connection via ethernet cable and through the use of a dongle/wireless chip (although I normally use the ethernet, dongle is just backup) on Windows 10.

This morning I started my computer (it was on sleep) and ethernet was showing that it was connected to an Unidentified Network, and had limited connectivity (which by searching for answers there are a lot of posts regarding the same questions, however all of the solutions posed do not work). However, by connecting to my router with the dongle, it works just fine and I can connect to the internet and browse, (I am not using DHCP on the chip, but I am for the ethernet).

When doing ipconfig, Ethernet Adapter Ethernet does not have a Default gateway assigned to it, but the Wireless LAN adapter wifi does (to the settings which I have put in manually). The autoconfiguration address for the ethernet adapter is also different, showing 169.254.x.x. When I try ipconfig/release and ipconfig/renew, renew does nothing after a few minutes, just showing Windows IP Configuration and a blank screen below it in command prompt. ipconfig/flushdns works, but I'm not sure if it's helping with it. I have also done netsh commands as well to no working avail.

I don't understand why it is not working as all of the other computers in my house are able to connect via ethernet, but all of the solutions I have found online do not seem to work thus far. If I try to apply the settings on the dongle to the ethernet settings for ipv4 it says that it'll conflict and as a result neither will work. Is there any other ways I could go about fixing this? I have tried searching a lot of different solutions but none have worked thus far.

You need to have admin access to your network's router.

Run "ipconfig /all" (without quotes) from the command prompt on one of your network computers.

The listed DHCP Server IP should be your router.

Enter the router's IP address via a browser and then enter the router's administrative Username and Password.

Admin access is needed to make changes to the router's configuration including wired and wireless features and functions.

For the most part many of the admin screens are self-explanatory but always good to get the applicable User Guide/Manual and do some reading and initial planning.

When you find the screens there should be some settings there - especially the available DHCP IP address range: starting IP and ending IP. May...

When you swapped adapters (i.e., wired to wireless or vice versa) are you sure that the other adapter is being disabled?

And does "I am not using DHCP on the chip, but I am for the ethernet" indicate that the dongle is configured with a static IP?

If so verify that that static IP is outside of the DHCP IP address range and that the static IP is reserved by the adapter's MAC.

Yes I am using a static IP on the dongle, but the DHCP settings apply to the ethernet ones. When I unplug the chip and switch to ethernet the wifi settings disappear, but when plugging in chip ethernet ones do not, and when it was working I could plug in the dongle while connected to the internet and it would also pick up an internet connection as well at the same time, and both keep it when the other is plugged out.

How do I verify that the static IP on the dongle is outside of the DHCP IP address range and the static IP is reserved by the adapters MAC?

When you find the screens there should be some settings there - especially the available DHCP IP address range: starting IP and ending IP. May also be some limit set for the number of devices permitted.

If no static IP addresses have been set then those configuration fields should be empty.

You want to make sure you understand the current setup before making any changes. If something goes wrong then you can go back and reverse the change. Make only on change at a time.
