hi all,

my bar code reader motorola MC9190 can't connect to wifi net with wpa/wpa2-tkip psk. i receive the following error:

TKIP MIC errors reported in EAPOL key msg from client 40:83:de:89:0a:33

WPA_KEY_MIC_ERR: 1x_eapkey.c:618 TKIP MIC errors reported in EAPOL key msg from client xxxxxxxcxcc

if i connect the same client on autononous ap work perfectly, who can help me? 

i verified the pre shared key,but the device can't connect.

Use either WPA or WPA2.  Don't enable both and "expect" the wireless client(s) to choose because they won't/can't.

i solved the problrm, i found a mismatch on a pre share key.
