I tried the preinstalled desktop image of Ubuntu 23.04 (Lunar Lobster) Beta last night. It has the same problem, as expected, but it was a bit tricky to fix it directly on the disk image.
There are two files called 'cmdline.txt', one in each of the disk's two partitions: 1. system-boot/cmdline.txt <-- Modify this one. 2. writable/boot/firmware/cmdline.txt <-- NOT this one. The file is found as '/boot/firmware/cmdline.txt' when running, so I added the command-line argument to the second file. That's the wrong one, though. The partition labeled 'system-boot' is mounted as '/boot/firmware', hiding the directory with the same name on the second partition with the label 'writeable': $ mount | grep boot /dev/mmcblk0p1 on /boot/firmware type vfat (rw,relatime,fmask=0022,dmask=0022, codepage=437,iocharset=ascii,shortname=mixed,errors=remount-ro) The correct file to modify on the disk image is the first one, directly in the 'system-boot' partition. By the way, you might wonder why I don't just change the access point's channels, but those high-end 5-GHz channels are the only ones that work well here. The 2.4-GHz channels are saturated by more than 150 access points nearby, and the same with the low-end 5-GHz channels. The high- end channels in Canada from 149 to 161 are far less occupied, fully available (not just for "indoors"), and don't have any Dynamic Frequency Selection (DFS) or Transmit Power Control (TPC) restrictions.
