That's correct AFAIK. > If this is not the case, then why is iwlwifi-8265-20.ucode no longer > required after providing 21, 22 and 27? The iwlwifi driver supports a range of firmware versions. It tries to load them all until one succeeds, starting with the highest supported version. You will see log messages for the missing versions, but these can be safely ignored as long as a supported firmware is eventually found. The installer just reports the list of file names the driver tries while probing for a supported firmware. The driver in stretch does not support version 27, so providing it makes no difference. Providing version 22 makes the driver succeed at that point and therefore not attempt to load any lower versions. So you (and the installer) don't see the requests for the lower versions. Providing version 21 along with version 22 is pointless, unless you plan to use an older version of the driver which does not support version 22. None of this should affect your ability to connect to the net as long as there is at least one supported firmware version available. Note that the different firmware versions do not necessarily exist even if the driver tries to load them. They represent different internal API revisions, some which might never have been made public. So there is no point going hunting for iwlwifi-8265-26.ucode. Use the iwlwifi-8265-22.ucode as provided by the firmware-iwlwifi package (in non-free). Bjørn
