• Enable simultaneous Hotspot/AP & client-WiFi on RPi's internal WiFi? #430
• Wifi3 - simultaneous AP & WiFi-as-client on RPi (using dnsmasq) #697
• rpi-test: wpa_supplicant AP mode simultaneous with WiFi as client #748
• Opening up ports [needs better documentation!] + DNS/dnsmasq failure when installing IIAB over WiFi #1519
• Admin Console should offer iiab-hotspot-on|off functionality [and explain command-line alternatives, which are often necessary!] #1520
• RPi installs w/ Ethernet AND WiFi very flaky: (1) disconnects all ssh sessions (2) forces auto-creation of unwanted hotspot #1527
