whenever see networking act this, it's not been driver issue, rather network manager issue.
i'd try deleting network network manager, , recreating scratch.
right click network manager icon > edit connections
delete related home wifi connection wireless tab.
use network manager connect wifi fresh. enter network authentication key.
see if problem reoccurs.
