Some early observations
USB clients can appear to be a bit slow (performance) depending on drivers, USB port version, etc. We
have also seen some clients that have trouble maintaining an 80 MHz bandwidth in the DFS (Dynamic
Frequency Selection) bands. Also, we have observed one USB client that did not work well from a client
band steering perspective (meaning we try to send the 802.11ac client to the 802.11ac module) but the
client keeps attempting to associate to the integrated 802.11n radio. These are all early client issues and
we are actively working with the manufacturers to resolve these early issues and will likely happen with
firmware or driver updates.

Radio Interfaces and Understanding Client Associations
As previously mentioned; the Access Point with module has three radio interfaces “slots 0-2” and shares
the same RF power characteristics and SSID’s. This permits the both radios to function as a “virtual” or
blended radio therefore (RRM controls both the integrated radio and the module radio).

Given there is no “greenfield” 802.11ac mode, RRM, Rogue AP detection and SI (Spectrum
Intelligence) all continue to function normally.
