6. Network Hardware Preparation

• Step 1: Internal Wi-Fi vs External Adapter Decision

  Most laptops have built-in (internal) Wi-Fi.

  Sometimes:

  • Internal Wi-Fi works fine

  • Sometimes it does not work well with Tails

  • Sometimes an external USB Wi-Fi adapter works better, also avoiding internal logs for better security

  So you decide:

  • Use internal Wi-Fi if it is detected and stable

  • Use external USB Wi-Fi adapter if internal Wi-Fi is missing or unreliable

  Simple idea:
  If built-in Wi-Fi works, use it. If not, use a USB Wi-Fi adapter because it’s highly secure.

  Step 2: USB Wi-Fi Adapter Recognition

  If you plug in a USB Wi-Fi adapter:

  • Wait a few seconds

  • Watch if the system notices it

  • A new Wi-Fi option may appear

  Good signs:

  • Wi-Fi networks start showing

  • No error messages

  Bad signs:

  • Nothing changes

  • Adapter light stays off

  • Wi-Fi still missing

  Simple idea:
  The system must “see” the adapter to use it.

  Step 3: Driver Loading Observations

  A driver is what allows the system to talk to the Wi-Fi hardware.

  What you may notice:

  • Wi-Fi appears after a short delay

  • Network list suddenly shows up

  What this means:

  • The driver loaded correctly

  • Hardware is usable

  If Wi-Fi never appears:

  • Driver may be missing

  • Adapter may not be supported

  Simple idea:
  If Wi-Fi shows up, the driver is working.

  Step 4: Radio State Awareness

  Wi-Fi works using radio signals.

  Things to check:

  • Wi-Fi is turned ON

  • Airplane mode is OFF

  • No hardware Wi-Fi switch is disabled

  Sometimes laptops have:

  • A physical Wi-Fi key

  • A function key that turns Wi-Fi off

  Simple idea:
  Wi-Fi must be turned on to connect.

  Step 5: MAC Address Exposure Concepts (Basic Understanding)

  Every network device has a MAC address.

  • It is like a hardware ID

  • Networks can see it

  Important to know:

  • Exposing the real MAC address can identify a device

  • Tails helps manage this automatically

  • Users should just be aware, not worried

  Do not:

  • Change advanced settings unless you understand them

  Simple idea:
  Your Wi-Fi device has an ID—Tails helps protect it.

  Step 6: Final Network Readiness Check

  Before connecting to Wi-Fi:

  • Confirm Wi-Fi hardware is detected

  • Confirm Wi-Fi is turned on

  • Confirm you see available networks

  Only after this:

  • Move to connecting to a network

  • Start the internet connection process

  Simple idea:
  Make sure Wi-Fi is ready before trying to connect.
