Cant connect tow WiFi after updating to 19.07

I have TP Link MR3220 which I updated to 16MiB nor flash, compiled 19.07 and I placed art partition at '0xff0000' but now I can scan networks but I cant connect to any

Any tip ? TNX

Reference (for others): Upgrading my 4/32 MR3220 v1 to 16/64

This is something the person making such a modification (i.e you) would normally solve.

Seems corrupted or not read to me.
