In which locations is it mandatory to register the MAC address?

PT

Target Audience: Iscte Community

Answer/Solution:

MAC Address registration is required in non‑shared spaces, such as offices and administrative services.
In classrooms, auditoriums, laboratories and study rooms, you only need to plug in the network cable to get access.

I plugged in the network cable, but I don’t have Internet access. What should I check?

PT

Target Audience: Iscte Community

Answer/Solution:

- In offices and services, access to the wired network requires the network card MAC Address to be registered and active.
- Without registration, the device may connect physically but will not gain network or Internet access.
- Also check that your network settings are configured for automatic IP assignment (DHCP).
