Hello brainy folk,

I am new in mikrotik. i am using omnitik as AP and SXT lite5 as CPE, but now getting errors as per below attachment. Only 1 or 2 sxt getting data transmit and other 4 sxt only connected as PPPOE but not transmit any data.

Check your spectrum, those kind of errors usually indicate bad wireless communication, due to noise, channel overlap, bad fresnel...

Add Tx/Rx CCQ tab on Wireless > registration table and post screenshot. (via the downright pointing triangle on the rightmost of the column label > Show columns...)
