WiFi can't switch the connection to wifi hotspot when already connect to an AP
 
Hi all,

I develop the Wifi for Android tablet, and found an issue.

Issue: WiFi can't switch the connection to wifi hotspot when already connect to an AP.

Also, The issue just happen when the hotspot's security set WPA2 PSK.

I cature the log as below:

WPA: 4-Way Handshake failed - pre-shared key may be incorrect
Setting scan request: 0 sec 100000 usec
BSSID 00:27:19:fd:ca:94 blacklist count incremented to 2
CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys


I found some treads also had same problem, but no correct solution for it.

I need your help, thanks.

I honestly don't know, but it seems like the problem starts with the handshake. It seems like there is an issue with the password. Have you checked the password to make sure it is correct?

Hi,

I search the key word "4-Way Handshake failed" and many people have same problem.

It seems like wpa_suppicant bug.

Also, I am sure that password is correct.

There have similar problem as the link. But I am not sure that the solution is correct or not.
