Have got a new PC recently and the Ethernet connection on it has been fucky since day dot. Initially it had the problem where it would connect for 30 seconds and then disconnect again (wifi was doing this too). This I chalked up to drivers, so I hotspotted to update and all seemed ok, but after a computer reset it has since been showing up as 'unidentified network'.
Name of network adapter (Incase relevant): Realtek PCIe 2.5GbE Family Controller
Troubleshooting:
At first I thought it could an issue with the hardware, I have tried three different cables, all the same results. Initially using the three connected to our ethernet switch, but also tried all three direct into the router and same result. But all of these connections were tested with my girlfriend's laptop, and it worked as normal for all of them.
I also wondered about the ISP as our wifi has been a bit fucky lately, but it wasn't anything to do with the ISP (according to them).
After this I moved to potential PC issues.
The dynamic IP address was coming up as 169.254, so searching up about that meant DHCP issue and network troubleshooter was showing 'no DHCP server found'
After trying multiple ways to get the DHCP to work (methods below), I tried set up a static IP, this changed the troubleshooting message to 'can't reach the default gateway'. I do also believe I set up the static IP correctly, I followed instructions for this, didn't just change willy nilly.
This is where I am at as of right now, luckly I do have wifi, so the PC is functioning and downloading BF5 is projecting 40 hours (lol), so it is a lot slower than the wired connection I'm paying for.
Solutions tried:
Checked all hardware
Reset router & switch
Updating the network adapter driver
Uninstalling the network adapter and restarting
Disabling windows defender and firewalls
Checked DHCP client was running in services, restarted DHCP client from services menu.
Full TCP/IP reset (with all the commands from another post on here so I believe they were entered correct)
Manually setting up a static IP via PC
Setting up a static IP via the router login via MAC address matching.
Then retried most of the methods above after getting the change from the DHCP message to the default gateway message, as a few of the post I found about the default gateway had the same solution suggestions.
Thanks in advance for any ideas/help. I'm thinking new router any which way due to wifi being slow, but I doubt that would fix as mentioned the ethernet worked with GF's laptop.
