Hi, I leave in a 4 stories house. My router is Archer AX6000 and is OneMesh enabled.

I have a RE330 which is OneMesh enabled at level 3 and it work well.

For some reason, my level 4 get very weak wifi signal, so I added another RE330 in level 4 .

And when I check Tether app to see the range, I always get out-of-range at level 4.

What is the best way to extend my OneMesh to level 4?

Thanks.
