6d06356 pointed wlan0/wlan1 at these SSIDs but wifi.networks still only
declared WhiteHouse, so hostapd evaluation failed on a null network. One
SSID per band on lan, named like the GL-AR750 being replaced; passphrases
come from the wifi-GL-AR750-passphrase / wifi-GL-AR750-5-passphrase prompts.
One dual-band SSID "WhiteHouse" on lan (replaces the liminix router's
WhiteHouse/WhiteHouse-5), WPA3 transition, WiFi 6, old channels 2/36,
country TH. Band mapping wlan0=2g/wlan1=5g assumed from mt7986 phy
order; verify with `iw phy`.
