Tried to write this this morning, but apparently something ate my post.

I had some issues with wlan completely disappearing which might be useful to mention here.

- I first flashed m4r0v3r's original build (the mega.nz download), which worked as well as could be expected, including wlan
- The only issue with that image was that it didn't have support for Jolla accounts or the store, so I then reflashed to the second image from the first post of this thread
- To my surprise, wlan didn't work at all. During initial setup I got the prompt to select a wireless network, but it said that wlan was off and no matter how many times I tapped the button to switch it on, nothing happened.
- After skipping setting up wifi, I found that the entire wlan device was just not there. Messages in dmesg seem to indicate that the wlan card just doesn't power up correctly anymore.
- Rebooting doesn't help, re-flashing sfos doesn't help

After some investigation by #sailfishos-porters (Thank you sledges and vknecht!), it seems that the only workaround is to:
- re-flash Android (I used the downgrade procedure from sailfishosmods.de to flash back to Marshmallow)
- go through the setup procedure for Android and connect it to a wireless network (just discovered this: it doesn't work if you reboot before actually having connected to a network)
- then switch off and flash sfos again

I thought it had something to do with my setup: I have the same network on both 2.4 and 5 GHz with different BSSIDs and hidden SSID. Only enabling the 2.4 GHz network does not seem to make a difference, I'll try unhiding the SSID when I next get some time to reflash.
