WiFi is slow
Check for any non-wifi interference or load on the AP channel by looking at capacity SLE’s and channel graphs from VNA
On the ‘Non WiFi interference’ classifier under the ‘capacity’ SLE, one can check:
- Distribution and verify if the ‘WiFi being slow’ is reported from the specific area or Access Points with high ‘Non WiFi interference’.
- One can also look into Timeline and Affected items.

This will rank channels by Client Event Count during the day
- Check if ARP and ‘Broadcast/Multicast’ Filtering is enabled. If not request to enable ARP and Bcast/Mcast traffic on the WLAN.
