The issue is that we upgraded the kernel (to add Pi 4 1.5 support), but the Wi-Fi drivers for some external dongles are not available on this kernel.
The additional WiFi drivers (not included in Pi Kernel) are fetched thanks to the work of Mr Engman, which compiles and hosts them (he is the creator of install-wifi script).
Unfortunately, it seems that the latest kernels have not received his attention and the drivers are not compiled.
We are studying a way to fix this, but it’s not a trivial task. We are deciding if:
- Stick with old kernel until we find a solution (which is a short-term situation), which will require some “hack” to make it work with most recent Pi version.
- Go on with newer kernel and don’t support many external wifi dongles
Sorry but this is not going to be solved very soon, as its quite a tough call and we are investigating.
If you guys have suggestions, let us know
