Network administrator needs a more complicated method if wants to monitor and optimize the quality of wireless. In Nebula Pro pack, Wireless Health feature uses a clear graphic to display the health status to let you know health of wireless networks for your APs and connected wireless clients.


In spite of monitor wireless health, Nebula helps user to optimize the wireless network by enabling auto optimization actions if wireless health has reaches the threshold.


To monitor and configure the wireless health, go to the page Access Point > Monitor > Wireless Health


The first panel shows the current online APs’ status using the specified frequency band. Nebula calculates the health of APs and categories into 3 status: Good, Fair or Poor. You can select 5GHz or 2.4GHz to view the health report in each band. The report can be showed for the Last 24 Hours, Last 7 days or Last 30 Days, as well as filter the AP to view.



Top APs by health alert lists how many times the AP is in a poor state.




You can enable auto optimization to take actions by DCS or changing channel bandwidth to improve wireless network if poor state has been detected. After triggered, AP will not stay in the current channel and bandwidth at least 4 hours to provide stable service for wireless clients until next possible auto optimization.


With selecting Adaptive Channel width option, AP changes channel bandwidth from radio setting to 20MHz if poor status detected. Because use only one channel can reduce the radio interference with other APs. Channel width returns to radio settings when health recovers.


Select DCS option to have AP scan and choose a radio channel that has least interference.


Note: In AP firmware version 6.10 and later, if Adaptive Channel width does not improve wireless performance then AP performs DCS and uses 80MHz channel width. If the AP still shows poor health, change channel width to 20MHz. Then AP stays 4 hours even if health is still poor to avoid wireless clients have unstable user experience. After lock time, channel width returns to 80Mhz and process is repeated.


This panel shows the current online clients’ status using the specified frequency band. Nebula calculates the health of clients and categories into 3 status: Good, Fair or Poor. You can select 5GHz, 2.4GHz or All to view the health report. The report can be showed for the Last 24 Hours, Last 7 days or Last 30 Days, as well as filter the wireless stations to view.

 



Top clients by health alert
lists how many times the client is in a poor state.



You can enable Clients auto optimization to have AP try to steer the wireless clients in poor health to an AP or SSID with a strong signal every 30 minutes.



In the Access Point > Monitor > Event Log, you can select Wireless Health in Category to view logs.
