For more details, read our

# Known issues
* Remove firmware for the Wi-Fi interfaces based on the BCM4301 and BCM4306 chips. ([#20887](
https://gitlab.tails.boum.org/tails/tails/-/issues/20887))
We believe that these interfaces are only available on computers that are too
old to start Tails. Please [let us
know](
https://tails.net/support/index.en.html#talk) if your Wi-Fi stopped
working in Tails 6.15.
# Get Tails 6.15

* Automatic upgrades are available from Tails 6.0 or later to 6.15.
* If you cannot do an automatic upgrade or if Tails fails to start after an automatic upgrade, please try to do a [manual upgrade](
