Hi! I have discovered some things here.. 802.1x is supported by n810. But Cisco has "migration mode". And if this mode is enabled in 802.1x network, so n810 is uncompatible to connect. "Migration mode" means that device can use WEP encryption and WPA encryption together, in one network. gadgets which can do both, cannot understand which one they will use. It seems that the problem inside driver, or, even in firmware of wifi chip.
