Network Disconnections

In the specific area where the application issue was reproduced, this screen indicates that frequent roams and roam failures are leading to packet loss and Wi-Fi disconnections, and the application cannot reach the network.
Item
Description
1
Green line – roaming from one AP to another
2
Red line – disconnection from the AP
3
Black line – connection to a new AP
4
Thick black line – connected to an AP for specific duration
5
Disconnection from AP and connect to a new AP
6
Frequent roaming
In this situation, it is imperative to determine the underlying cause for the roam failures and disconnections. To do this, stop the
Device’s Coverage View
feature, navigate to the
Roaming Analysis
feature, and use the
Setting
menu to run in
Active
analysis mode.
Run the feature and repeat the roaming sequence in the same area with the same operational use case.
Navigate to
Monitor & Reports
and observe real time reports while roaming and performing the operational tasks of the disconnecting application.
Item
Description
1
Association failure: unable to handle STA/client (wireless infrastructure)
2
Association failure while roaming from one AP to another; max STA limit reached
3
Deauth packet leads to L2 disconnect
4
High packet loss causes application disconnects
The reason code “Association denied because AP is unable to handle additional associated stations” indicates the Max Stations configuration (maximum connected devices per AP at a given time) cannot accommodate respective crowded scenarios, which are dynamic in nature.
To address this, increase the Max Stations value in the infrastructure (or adjust the configuration per AP/infrastructure vendor recommendation) to accommodate the use case as per infrastructure guidelines, and then re-run the Roaming Analysis feature in active mode while performing the same use cases to confirm the new data accurately reflects the updates.
The following screen depicts a good outcome after the WLAN changes, indicated by
Roam Completed

Roam Completed indicates successful roam (without failure)
After verifying roaming performance, run Coverage View to confirm coverage and connectivity in the same location.
