PS5 No WiFi. No WiFi MAC. BT works fine

It is a 1216A edm-031 ps5.

I bought it as defect with desoldered southbridge. In the end it was the wrong southbridge (61gg) for the board which was populated for a 69gg sb. I changed the layout, so the 61gg could work and altered a nor dump.
The ps5 is now turning on again and is full functional, besides it will not see/connect wifi accesspoints and it shows no wifi mac adress in the system settings. The nor data shows the correct mac as written on the ic and BT is working fine.

Any ideas or experiences with not working wifi but booting fine?
