FYI, TP-Link support sent me another beta firmware today that was supposed to fix the issue (1.0.0 Build 20221028 Rel. 54577). It doesn't work for me though. It seems to allow DHCPv6 Advertise...

@CuBiC Agreed. Still waiting for a firmware update. FYI, there's another thread about the issues here.

Yes, I've given them a link to this thread and pointed out it's affecting the EAP670 too.

Update: TP-Link have confirmed they can reproduce the issue in their lab. Anyone know from past experience how long it's likely to be for a fix (or at least beta firmware) to be released?

@GPB From my analysis using wireshark on a mirrored port on the core switch, the router sees all packets from the client (i.e. SOLICIT and REQUESTs) and sends the appropriate ADVERTISE/REPLY packets...

@GPB Yeah, got a support case open. I'm fairly certain it's a firmware bug, but they haven't confirmed yet. I'm using a PfSense sense router, which is running my DNS and DHCPv4/DHCPv6 etc.
