Same problem here on Ubuntu w/Dell 9310 and AX500. Reverting to 5.13.0-19 resolved the issue. First reboot didn't fix the issue, but a full power cycle did.
I used a USB wifi dongle to install. Without that, you might need to grab the relevant dpkgs and put on a USB stick to update. sudo apt install linux-headers-5.13.0-19 linux-headers-5.13.0-19-generic linux-image-5.13.0-19-generic linux-modules-5.13.0-19-generic linux- modules-extra-5.13.0-19-generic -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1950492 Title: wifi stops working on Dell XPS 9310 Status in linux package in Ubuntu: Incomplete Bug description: After updating to linux 5.13.0-22 wifi stops working on Dell XPS 9310 with QCA6390.
