Why Is My Ethernet Connection Only Working for One Computer?

Your company likely uses Network Access Control (NAC), which makes it really difficult to bypass those restrictions. Trying to do that isn’t just risky; it could get flagged pretty easily. You're best off finding a legitimate way to ask IT for better connectivity options.

It sounds like your Ethernet connection is locked to your work computer's MAC address. This is a common security measure, and it would prevent any other device from connecting through that network jack. Your IT probably gets alerts when someone tries to circumvent this. So even if you manage to get it working with a Wi-Fi router, you're likely to trigger a security alert, which could lead to disciplinary action.

Unfortunately, if the connection is specifically set up for your PC's IP, there's probably not much you can do without IT's approval. The best bet would be to discuss this with your manager to get Wi-Fi access in the office. It’s really the safest option.

If they're using a MAC whitelist or similar system, it means trying to connect any new devices is pretty much a no-go. Instead of trying to hack around it, maybe just advocate for a Wi-Fi access point in your office. It'll save you a lot of headaches!

Yeah, messing with locked connections can get you into serious trouble. IT typically implements these restrictions for a reason. It’s probably not going to work anyway since they likely have network access tied to registered MAC addresses. You might want to consider talking to your supervisor about getting Wi-Fi access instead.
