Hi ,
I have detected same error on all SM's , on system log it appears
Unable to complete PPPoE Discovery
Interface ath0 has MTU 1492 - should be 1500 - you may have serious connection problems.
I am using Mikrotik routeros, with internet pppoe server MTU 1480 & MRU 1480
SM has ethernet MTU to 1500
PPPoE MTU to 1492
Max MTU for PPPoE is 1492, same error even when change RouterOs pppoe server MTU from 1480 to 1492
¿Which can be the problem?
Thanks
yep, same problem. pls fix it.
Hello Miguel,
You can ignore this error.
Interface ath0 has MTU 1492 - should be 1500 - you may have serious connection problems.
PPPoE mode only supports a maximum MTU of 1492 bytes. As long as you have made adjustment on your network configuration, as you have done in your MikroTik configuration, to not go beyond 1492 bytes, you are fine.
Saludos,
Luis
Aqui usamos 1500 e 1492 conforme imagem. Ainda assim temos este problema nos logs de erro e os clientes relatam que perdem a navegação quando o erro ocorre.
