This one is Broadcom ARM CPU and wifi5, so wifi5 part is absolutely not supported by open drivers. I would not put much hope in 2.4GHz being older Wifi4 that one could squeeze out wifi4 of whole device.
This is Mediatek, albeit very minimal spec device, still very well supported, likely RAM restricts it to dozen clients and flash does not permit installing any significant extra packages. Install process needs a lot of care, but very well supported. 2x bigger device (in antennas, ram and flash) costs about 20 bucks nowadays.
