My laptop is an old Sony VAIO (model number: PCG-7185L) and I have been having this reccuring issue regarding connecting to the internet via an Ethernet cable. I am now in an internship in Germany and this issue is happening in my student dorm. There is no the issue with the connection (I have contacted the persons in charge) as I have tried it with another device running Linux (I changed the MAC address of that device to match mine because worked fine the contract is in such a way that I can only connect one device) and the internet worked fine.
I need to mention that connecting via Ethernet cable worked before (last time was on Monday) so it is not a configuration issue. I also excluded any possible driver issues.
To describe in more detail: If I plug the Ethernet cable there is the pending circle on the internet connection for 1-2 seconds. After that you can very briefly see the yellow exclamation mark that turns immediately into a red X (as if the cable wasn't plugged at all). I have tried detaching and reconnecting the cable (on both ends) and still no luck. I contacted the responsible persons to reset my access point and still it doesn't work (on the Laptop with Linux installed it works fine, but that is not my laptop). It may be a hardware issue?
Just to note, The wifi connectivity works fine (on networks at the university) but I cannot connect to wifi in my room unless I cancel my (wired) contract and opt for the wireless one. I really don't want to do that as there is less bandwidth and the connection is not as reliable in terms of signal.
Looking forward to possible solution to the issue.
