The important piece of information in your LOG output is this line:

  [init -> wifi_drv] dev_error: Invalid 11n configuration

When your 6200 ABG card is initialized it indicates that it supports the
11n mode but judging by looking into Linux driver it is not supposed to
be configured this way. I vaguely remember that Norman has the same
problem with his 6200 ABG card. The “quick-fix” is to forcefully disable
11n support (see the attached patch).


Regards,
Josef
