<p style="margin-top:0;margin-bottom:0">This sounds like a different issue we have seen in the past with different CPE vendors where they were sending LCP packets with a class of service other than best efforts (0) - while this worked with some PPoE sessions,
it failed on others with AAPT. Configuring the CPE to send only LCP with best efforts overcame that particular issue.</p>
