I noticed a weird problem today on my laptop. Apparently, it only connects on the Ethernet cable located on to my desk but not in any other port in my office. When I tried to get connected using a land cable of a different desk, the networking icon on the status bar showed an exclamation mark and refused to connect. Though this is a large company I am working at, they have not applied any restriction policy "laptop per Ethernet plug", so it must be something software or hardware specific. I have tried to
renew my IP address, reinstalled from scratch the network drivers and contacted the IT help desk; no fix so far.
Is there any possibility that my network card starts degrading or is in a bad state? The laptop is only 6 months old. I have tried with multiple land cables and different plugs, it connects to my desk only.
PS: Laptop successfully connects to the open WiFi of my company and to networks outside the intranet.
