The MESHING and DFS are two different things.
I am hoping they fix the MESHING stability issues when 26.3 comes out, since I know they are fully aware of it.
In the interim, I would re-enable MESHING (if you have it disabled), until they fix it. What you want is stability, and re-enabling it will give you that at the cost (very minor cost) of some overhead of beacon frames being sent at lowest data rate/max power.
I'm not aware of any DFS issues though, so that is new to me.
