Preparation guide

  1. Inspect the actual Intel unit. The guide marks standard Ethernet and Ethernet extension/docking hardware as configuration-dependent; an extension connector is not a standard network socket.

  2. Use a fitted standard Ethernet socket or a documented compatible dock. If the unit has a capped or absent extension connector, follow the guide’s docking compatibility warning.

  3. Connect an undamaged cable to a permitted known-working port. Record Windows wired-network status before testing internet access.

  4. If permitted, change only the Ethernet cable while retaining the same port and laptop path. Alternatively compare a permitted device on the original cable/port; identify which comparison was done.

  5. A wired link without internet may require network authorization or administrator review. A shared failure across devices goes to the network owner; do not change managed addressing or network policy here.
