I found that in the latest kernel package (5.18.9-1) the WiFi hotspot functionality can’t work (at least not completely). The network appears and DHCP works, but there’s no internet access. This is because the PP kernel is missing a few build parameters. I just rebuilt the kernel to test my theory and hotspot now fully works. That being said, I’m not a kernel dev and I think I enabled way more CONFIG_NF_ parameters than I had to. I think the ones that are required are CONFIG_NF_NAT and CONFIG_NF_TABLES.
Note: In my testing using the GNOME Settings for setting up the WiFi hotspot not always succeeds. If it doesn’t, you can use nmcli d wifi hotspot ifname wlan0 band bg password aaaaaaaa ssid a con-name a. This works every time for me.
Here’s a diff of the two kconfigs:
