cannot connect to access tp-link

hello every one
i have a station of routerboard and car wireless
it’s working very well
all clients’service is ok
but i bought a new access point Tp-LinK (Tl-WA701ND-v2)
i made all settings " wireless mode is client … etc "
i got a signal of 51 db i saved my settings and rebooted
but the surprise was that the counter of sent paquets on access is working and the counter of the received can’t work
i mean it’s zero
i guessed it may work when i get an ip from the station and have a bandwidth
so i logged out from the access webpage
but i can’t get an ip from access

when i logged into mikrotik via winbox
i found the mac address of the access which start with 64:70:… found on registeration
but it disappear after 2 seconds or less
i opened log i found alot of messages which are " : as shown


by the way i tried the access to recieve from an access point station and it worked well

i saw this

but on vain
waiting for help
thank you all
