Hello,
I have some problem with my home 2 APs, I have configured with 802.11r Fast Transition with same Mobility Domain.
The problem is that sometimes the mobile phones has no connection, the client is associated in both APs in the same time:
Is this something normal? Or need I configure something else?
Kind regards.
You haven't given us much to work with here. What troubleshooting have you done? does your network function properly with other wifi devices? How are the two APs configured (hint: you should have non-overlapping channels and power levels as low as possible to cover the necessary area with as little overlap between the APs as possible). How are things physically connected (a network topology diagram could be really useful here)?
Not all devices support 802.11r -- if you disable that, does it work any better?
For the both devices, please copy the output of the following commands and post it here using the "Preformatted text </>
