Problem with PPPoE over WIRELESS

hello, i’ve problem with PPPoE over WIFI,regardless ROS version or models Routeros ( QRT,NETBOX,METMETAL), distance between BTS and CPE, numbers of CPE:

offen not established PPPoE between BTS and CPE (not all CPEs but 1-3 for BTS),but if i enter through mac-telnet ( from BTS to CPE) it established


I think that it is a problem a wireless setting, because same PPPoE configuration on ethernet interface does not give this problem


I tried to change:

  • nv2 ;TDMA period size 2- auto

  • ROs versione from 6.19 to 6.40.2

  • reduce number of CPE until 8-10






    export config BTS
