Wirelss Client disconnects

Hello Experts,

I have LWAPs and WLC installed in my company. few of my wireless clients get disconnected from the network without any reason, and they do not auto reconnect unless they manually reconnect to the SSID.

This issue just started a couple of weeks before, without any changes to the configuration of my WLC.

Can any one let me know what can be the issue?

what's your AP and WLC model and code ?

Following actions can be taken to prevent client disconnections:

1. Proper site survey that will prevent any type of interference OR use some modern WiFi system that can avoid interference through advanced channel selection algorithms
2. A good site survey will also ensure good coverage and optimal data rates
3. Use open authentication system if the issue is related to encryption or authentication
4. Make the wireless a known system if wireless intrusion prevention system is on the network
5. Use standard beacon interval and data rate for management traffic
6. Update drivers or update radio hardware on the clients
7. Physical inspection of the coverage and surrounding areas for any recent changes
8. Install latest software on the wireless system
9. Add more APs if the existing APs are overloaded
10. Adjust roaming aggressiveness on the stations
11. Attempt to connect to a single frequency instead of keeping both radios enabled. For example, if the 2.4 GHz is not usable, make use of 5 GHz spectrum.
12. Replace or move the AP to a different location
13. Check network connectivity
14. Use local breakout instead of tunnelling traffic to the controller
15. Make sure client radio is enabled or disable and then re-enable the radio
16. Check the country code setting for any incompatibility if 802.11d is enabled

Use Spectrum analysis tool to find RF interference, if only single AP has issue try to replace with spare AP and check the issue.
