Hi All,

We are facing very serious issue with Intel Wireless - AC 9560 Adaptor in lenovo X series of laptops. The users are dropped suddenly and sometimes disconnected from the network. but we have other series of laptop which is T4xxx from lenovo thats working perfectly.

Can anyone help and share his experience. We just need to understand that the issue is with clients or its with our wireless setup.

Also, we are getting the below logs on the wireless health portal:

@Ammar-Tanveer01 what adapter is in the other Lenovo laptops?

If this is happening when on battery power try disabling the wireless adapter power management, set it to "Maximum performance"

If this is happening when connected to the power supply then it is the authentication issue you are suffering from, see those threads for suggestions.
