@newspatron I run #Kiwix on Raspberry Pis. The built-in Broadcom wifi of a Raspberry Pi is quite poor. I found a couple of different inexpensive USB wifi dongles that work great in Raspberry Pi OS. A dongle supporting 802.11AX is best. These dongles can transfer upwards of 24MB/sec over wifi to an inexpensive 802.11AX #OpenWRT router. The most ideal of these dongles - great low latency, largest antenna - had a Mediatek chip (much harder to find in the market), not Realtek (all too easy to find, often not supported in #Linux )
Note: I don't use the Kiwix hotspot all-in-one OS, but rather plain old Raspberry Pi OS, then set up the kiwix web server to start at boot time with a systemd service.
