Even if you connect your laptop to a Ethernet port using an ethernet cable, is logging into wifi still required? For example: school library?

    no, but their network may not allow you.

    and that port may not be active.

    Most companies use various methods to block wired access, NAC, port security, 802.11x, or capitve portal (like wired).  This prevents unauthorized users from just plugging in and access things.

    The way it is implemented is using Vlans.  When you iniitailly log in, you are assigned an unauthorized  user's Vlan.  If you pass the network checks, your Vlan is changed to the authorized network.

    Your home network relies on physical security and your network doesn't have Vlans, so such security is not needed.

    use device manager to disable you wireless network adapter when you're using ethernet.  I don't recall whether windows (or MAC) defaults to wireless or ethernet if both are available. If you disable wireless, your 'puter won't ask for a wireless p/w.  but as others have said, that wired network could still require a login.

    When your at home you can use the Ethernet Port or the WIFI.

    But when you go to the Library, you to use WIFI as they don't have Ethernet ports to connect to.  (unless you have a very advanced library with desks for computers).

    Wi-Fi is an alternative to Ethernet.

    Your school library may require to login regardless of how you make the physical connection to the network.  It's called Network Access Control.

    No logging in via WiFi but if you still need to log into the school’s network then you would need to log in anyway

    No, and if it is, the login thing is called RADIUS.

    No ... assuming the ethernet connection is to the same router as the wi-fi connection.

    If the Ethernet cable comes from a router with working internet access then you don't need to use the laptop's wi-fi. Ask the computer tech administrator if unsure if an internal network has internet access and how to use it.
