0. Don't have a SIM card in when you're updating radio firmware or it will bomb out partway through as it changes from internal IP to IP passthrough

1. Disable external IP passthrough mode: Network Setting -> Broadband -> Cellular APN -> #1 -> Modify icon -> "IP Passthrough" slider to off

2. Use "management" Wi-Fi AP as general Wi-Fi AP (with limitations) -> Network Setting -> Bridge1 -> Modify icon -> Move the Wi-Fi AP interface to the pane on the right alongside LAN1
NOTE: by default, once you do the above, the router will happily pass traffic from devices on the Wi-Fi AP to other devices on the LAN1 subnet, but will block traffic originating from the Wi-Fi AP from exiting to the Internet via the LTE side of the device. You can clumsily hack around this by setting another device, e.g. another Wi-Fi AP or Raspberry Pi or Cray supercomputer, as the default gateway for the LAN1 subnet in your DHCP server config, and pointing *that* device at the Zyxel as *its* default GW. This adds additional hops, but enabl

scaling hidpi: everything is very small needed steps:

• settings -> display -> scale = 1
• settings -> enforce fonts dpi -> 162dpi
• settings -> symbols -> scale up

• settings -> input -> keyboard -> extended -> toggle left alt with left win
• idea: help -> custom properties:
