Hi Michel,

There is a known issue with 2.0.1 and 20 MHz mode where the C5 gets stuck at low MCS and can not recover. This is documented in the release notes here: http://ap.help.mimosa.co/ap-firmware-release-notes-a5

We have a fix for this available in 2.0.2 beta, which I will send to you privately.

For future reference, we have more immediate support available through our chat line or by emailing support@mimosa.co
