RTW: ap has changed, disconnect now

[pbouchand]

Hello,

First, thanks a lot for your work!

This is not really an issue, but I would really appreciate it if you could shed some light on the meaning of this kernel message:

RTW: start auth
RTW: auth success, start assoc
RTW: send eapol packet
RTW: send eapol packet
RTW: set pairwise key camid:4, addr:7c:16:89:fd:9c:50, kid:0, type:AES
RTW: set group key camid:5, addr:7c:16:89:fd:9c:50, kid:1, type:AES
RTW: ERROR rtw_check_bcn_info: cur beacon key
RTW: ap has changed, disconnect now

I've used your driver on a bunch of different APs, and it's the first time I've encountered this issue. I've had it for hours, almost disconnecting every 2 minutes, and suddenly, it works like a charm for one day now.

Any ideas on what was wrong on the AP side?

Thank you!

I'm sorry to bother you again, but could you direct me to some documentation explaining what might cause the driver to determine that the 'AP has changed, disconnect now' ?

Thank you

The only documentation is in the source files. In routine rtw_check_bcn_info() in file core/rtw_wlan_util.c, any of the places where the routine does a 'goto _mismatch' is a candidate. I suggest that you add a 'pr_info()' statement before such goto statements to indicate which one is active.
