The iwlwifi module and drivers for the Intel 7260 are now included as part of the baseline LT4 21.2 release. After downloading the firmware for the 7260:
sudo apt-get install linux-firmware
and rebooting, wireless networks show up in the Network Manager as expected. However, if a WPA/WPA2 network is selected from the Network Manager, no dialog is presented asking for a password. Subsequently no network is selected. Non password protected open networks are connected to normally.
/var/log/syslog shows the following:
Jan 12 05:09:16 tegra-ubuntu NetworkManager[666]: <info> Activation (wlan0/wireless): access point 'Kangaboxer Wi-Fi Network' has security, but secrets are required.

Jan 12 05:09:16 tegra-ubuntu NetworkManager[666]: <info> (wlan0): deactivating device (reason 'none') [0]
At times, there is a dialog box which says:
Connection failure
Connection activation failed
(1) Creating object for path '/org/freedesktop/NetworkManager/ActiveConnection/3' failed in libnm-glib.
The connection can be manually configured, and will work as expected so I don’t think it’s a driver issue per se.
modprobe remove and reinstall made no difference.
If I compile the iwlwifi modules from the kernel source and install them, things work as expected.
Does anybody know how to fix this so that it “works out of the box”?
