Fp4 wifi problem after screen replacement

I replaced the screen on my fairphone 4. Now wifi doesn’t work. When i turn it on, it does not disppay any networks, and upon closing and reopening the window it is apparent that it turned itself back off again. Mobile data does work.

Thoughts?

Anyone? All the contacts to the case (presumably for antennas) seem to be fine. I don’t think i damaged any ribbon cables in the process. It does not appear to have any micro ufl or whatever antenna cables. I dunno how to proceed.

are you totalls ure you reconnected everything? did you follow some kind of a manual or a video?
