@Fae
Seems like this issue has come back on the EAP670 on latest firmware (1.0.15). 90% of the time I get no IPv6 assignment via SLAAC. I did some wiresharking and I almost never get the router advertisements following router sollicitaiton.

@starcraft66 Yes the issue has returned with the 650 as well. Kind of get the feeling that they've stopped caring about this issue TBH

My eap655-wall v1 was running at firmware level 1.4.2 when I introduced ipv6 on the network, and I had to fallback to ipv4 since packets were being dropped. If I read this thread correctly, the issue was resolved with firmware 1.2.4 (end of 2023) but resurfaced with recent firmwares. I downgraded the eap655-wall to firmware 1.3.1, but still had the issue. I downgraded again to 1.3.0 and now ipv6 is rock solid. I did not verify, but I assume it would also be OK with firmwares 1.2.6 and 1.2.4. Methodology to reproduce the issue: on a wireless client, start an ssh session to an ipv6 (wired) host. Then start a "top" on that host through the ssh session; within a few screen refreshes the session will freeze then timeout.
