Root Bridge Selection

shellswell — Sun, 04 Jul 2021 19:19:41 GMT

I have two root bridges - A & B - and I have one non root bridge - Z. The bridges A & B are broadcasting the same SSIDs and so Z can associate to either of them.

The directional antennas, line of sight and everything has been set so that Z would obviously choose A, and not B.

When it is associated to A, we have a signal strength of -55dbm. When it is associated to B, we have a signal strength of -75dbm.

Yet still over a period of time Z will dissociate from A, and associate to B, where it will stay associated.

We have looked at noise in the area, and although it is a very noisy environment, it is no more noisy on one As channel than B.

Do you have any ideas what may be going on here - why this would be happening?

I thought that Signal Strength/SNR was the deciding factor with which root bridge to associate to...
