Give Guest WiFi Lower Priority Airtime/Bandwidth

In cases where the WiFi network is congested (more so from an airtime perspective) I'd like to give Guest WiFi users lower priority so that the Private WiFi still gets decent throughput (i.e., sufficient airtime to accomplish their tasks).  However, in cases where's there's no congestion it's ok if a user hogs a significant amount of bandwidth.  For example, if only 1 users is online, they should be able to download at the maximum possible rate.

The best way to accomplish this is to use Dynamic Airtime Scheduling and configure an SLA with the "boost" action in the user profile for the private WiFi users. The system will then boost the airtime for the private users to try to meet the SLA at the expense of the other users' airtime (within the possibilities of the laws of physics and the needs of the protocol for management frames etc.)

You can also use traffic classification via the firewall policy to give specific applications a higher class of service than other traffic to further ensure the performance of your private users key applications.

Thanks!  This is what I did - look ok?

Guided Configuration > Additional Settings > QoS Settings > enabled Dynamic Airtime Scheduling.

User Profiles > select my 'Private' profile > enable SLA settings, Targeted Minimum Throughput Level = 3800, Action = Boost.  I arrived at 3800 kbps as it supports 1080p mpeg4 streaming.

Yes, that's the sort of thing!

Does it make sense to use this technique together with User Profile QoS > Scheduling weight?  E.g., the higher priority would have a weight 5x that of the lower priority User Profile.

Not really - those weights are for the relative weighting of the per-user queues.
