Hey everyone! I've recently had to connect my laptop directly to an ethernet cable at work due to some changes. I got a USB ethernet adapter, but when I plug it in, I only see "Unidentified Network," and I keep getting a message saying the network doesn't have a valid IP configuration.
I've tried various troubleshooting steps from the internet, including running console commands like /flushdns, /release, and /renew. I also checked the router settings in the front office and made sure IPv6 is disabled, but nothing has worked.
I tested the setup at home with my own ethernet, and it worked perfectly, so I'm pretty sure the problem lies with the office network. I'm not super tech-savvy and often feel out of my depth dealing with this stuff, so any suggestions on what I can try when I get back to work tomorrow would be greatly appreciated!

Have you tried resetting the network settings to default? To do this, run Command Prompt as an admin and type `netsh int ip reset reset.log` and then `netsh winsock reset`. This can help with those annoying random network issues. Just restart afterwards!
It sounds like the switch port you’re plugged into might be set to a VLAN without DHCP, or there could be an issue with the DHCP server itself. Try connecting your laptop to a port that another working computer uses, and if that doesn't help, it might be time to ask the IT provider for assistance.
It sounds like your DHCP server might be having trouble connecting with your laptop. If it's a small office, consider suggesting to your boss that they look into hiring a local Managed Service Provider (MSP) to help with these tech issues, as they can often resolve things faster.
Can you confirm if other devices are connecting fine? For example, is the office computer working well? If that's the case, maybe there's a specific configuration issue with your setup. How's the wiring from the router to your laptop? What’s your setup at work?
Your work might need to do some manual authentication setup to get everything running. But since you're the closest support they have, you might need to handle it yourself!
Thanks for the tip! Should I run these commands on my laptop or the office PC? I connected my laptop at home without any problems, so I'm leaning towards there being an issue with the office setup.
