If your Wi-Fi interface is not working, for example:
|
|
There is no Wi-Fi option in the system menu:
|
|
[[!img no-wifi/system-without-wifi.png link="no" alt=""]]
|
|
You receive the notification **Connection failed: Activation of network connection failed**.
|
|
The interface is disabled when starting Tails or when plugging in your USB Wi-Fi adapter:
|
|
[[!img no-wifi/mac-spoofing-disabled.png link="no" alt="Notification about network card being disabled"]]
|
|
In this case, you can disable MAC address anonymization to get your Wi-Fi interface
to work in Tails. Disabling MAC address anonymization has security implications, so read
carefully our [[documentation about MAC
address anonymization|first_steps/welcome_screen/mac_spoofing]] before doing so.
|
|
To connect to the Internet, you can try to:
|
|
Use an Ethernet cable instead of Wi-Fi if possible. Wired interfaces work much more reliably than Wi-Fi in Tails.
|
|
Share the Wi-Fi or mobile data connection of your phone using a USB cable. Sharing a connection this way is called *USB tethering*.

[iPhones or iPads](https://support.apple.com/en-us/HT204023)
|
|
Only sharing mobile data works on iPhones and iPads; sharing Wi-Fi does not work.

<div class="caution">
<p>Tails cannot hide the information that identifies your phone on the local network.
If you connect your phone to:</p>
<ul>
<li><p>A Wi-Fi network, then the network will know the MAC
address of your phone. This has security implications that are discussed in
our [[documentation on MAC address anonymization|first_steps/welcome_screen/mac_spoofing]].
Some phones have a feature to hide the real MAC address of the phone.</p></li>
<li><p>A mobile data network, then
the network will be able to know the identifier of your SIM card (IMSI)
and also the serial number of your phone (IMEI).</p></li>
</ul>
