I have RB 493G + R52Hn (+ 8dBi antenna). Wireless is in "AP Bridge" mode. There are 6 wireless clients in the house (2x Notebook, 1x MAC, 3x Smartphone). Encryption is WPA2 PSK (aes/ccm). All of the devices are in the AccessList. Problem is with one Smartphone (HTC Desire Z, AndroidOS). Mikrotik LOG is spammed by line "Data from unknown device xx:xx:xx:xx:xx:xx, sent deauth" (the MAC belongs to the smartphone). Another phone (Samsung Galaxy, also AndroidOS) does not have this problem at all.
Anyone know how to fix the problem?
