Howdy,
I have installed Kali over and over many times trying to track down this issue..
My LTE card, internal Sierra Wireless MC7355, does not connect if I install Kali 2022.1 and forward. If I install 2021.x and earlier, it does work, until I upgrade.. This most recent install I used 2021.3.
apt update
apt dist-upgrade
After I reboot, it does the same thing when I did a fresh install of 2022.x, as soon as I select the Mobile Broadband connection, the network disconnection notification appears. So Network Manager does 'see' it, I can setup the APN, it just won't connect. ip addr does show the wwan0 interface as down.
Where do I need to look to figure this out?
