Hey, im once again here. So yea the title pretty much explains it all.

The adapter is not hidden in other devices or in "show hidden" tab. Trying to install the driver resolves to the deep sleep mode error everyone is probably already familiar with.
https://prnt.sc/104o76o - This is how my device manager looks. The Intel adapter is a network card i bought to atleast have internet on the computer but it gives me other problems so i want to focus on fixing my onboard port. I have tried different cables, the ethernet lights turn on my router but not the PC.

Open Powershell.

Run the following two cmdlets at the PS> prompt:

Get-NetAdapter

Get-NetIPConfiguration

You should be able to simply copy and paste each of the above "Get's at the PS> prompt.

Post the results.

The results will be similar to the following (where X's represent my redactions):

Okay.

Run "ipconfig /all" via the Command Prompt and post the results.

Try the Intel Gigabit drivers.

https://downloadcenter.intel.com/product/50395/Intel-Gigabit-CT-Desktop-Adapter

[Do verify that I found the correct/applicable driver link.]
Yes, the drivers are right for the networking card i have installed into my pc at the moment to even have internet as i've explained earlier. But would it make a difference if i installed them? because the whole problem is in my onboard ethernet port and not the networking card that i have installed on a pci-e port. https://prnt.sc/105oajt

Three things:

1) You need the drivers for the Intel Gigabyte CT desktop network adapter. That is (per "ipconfig /all" ) the enabled/connected network adapter.

The adapter is requesting a DHCP IP address from your router at 192.168.1.254 and being assigned a DHCP IP address of 192.168.1.214.

2) Change your router's DHCP IP address lease time. Again, according to "ipconfig /all" the lease time is only 12 hours.

3) If your ISP does not provide IPv6, disable IPv6 on the enabled network adapter.

====

Also - right click the network icon usually located in the lower right screen corner. The icon looks a bit like a "monitor with a mouse on the left side".

The right click should result in a two item menu: 1) Troubleshoot problems, and 2) Open Network & Internet Settings.

#2 will make it easier to look at the overall network configuration and adapter settings.

To what time should i change the leasing time to? In the ISP settings the IPv6 is disabled https://prnt.sc/105phug

Leasing time: One week (168 hours). Overall, the leasing time should automatically renew DHCP IP address within the set time.

Overall lease time should not cause problems but if too short, with other possible problems, many network, devices etc then the process could get disrupted or confused. Idea being to eliminate lease time as a potential culprit.

And yes that is the Network & Internet Settings screen I referenced.

Use the screens/properties/options to explore the other settings and not necessarily start changing things.

Of most interest I think is that the Gigabyte adapter is correctly installed and configured.

No interface line? I would expect it to be 192.168.1.214

The first line is your router.

The second line is the broadcast IP.

From other devices are you able to ping 192.168.1.214?

Do you see 192.168.1.214 in their arp -a results?

Or if the assigned DHCP IP address has changed then ping that IP address. "That" being the IP address following Interface.

pinging the ip after the interface ip resulted in:

The "time=" values are very high.

What device is 192.168.1.217?

Now, instead of "ping" use "tracert" to target the devices you see appearing on the network.

And, after reading back, noted that you tried different cables. Where did those cables come from and what is printed on them?

and the other one came with the router/modem.
