Hello @Fae
Any ETA on the fully fixed IPv6 firmware for the EAP650, just like the one released for the EAP653? Beta or otherwise.
Thank you

Hello @s0x,
Have you already installed the following updated Beta firmware for your EAP650-Wall?
If the issue still persists with the new 1.0.3 Build 20230410 Beta firmware, please feel free to let me know.

Hi @Fae
I don't have EAP650-Wall, but 2 EAP650.
Due to the reboot and WiFi channel issue I'm running the 1.0.6 beta. Is the IPv6 issue fully fixed on this one? Or is version 1.1.0 (similar to EAP653) going to be released to address it?
I noticed that
EAP650(EU&US)_v1_1.0.0_Build 20221116 (Beta)
is now stricken through on this thread.

Hello @s0x
Sorry for my mistake to take the EAP650 as the EAP650-Wall, too many Beta firmware provided in this thread.
The 1.0.6 Beta and 1.0.0 beta for EAP650 are independent. I don't think the EAP650 1.0.6 beta has fixed the IPv6 issue as the 1.0.0 beta does. Besides, the EAP650 1.1.0 Beta should only fix the IPv6 issue.
Are your EAP650s suffering from both the IPv6 issue and the disconnected issue caused by weather radar channels? I haven't been informed of any newer beta firmware for the EAP650 yet, if you need further assistance with your EAP650, please feel free to let me know.
BTW, the EAP650(EU&US)_v1_1.0.0_Build 20221116 (Beta) link was just recovered.

Hi @Fae
No problem.
Yes, they're suffering from both issues, and being the readopt loop after reboot the most critical one, that's the beta firmware I'm running in them.
I've tried IPv6 on the beta firmware for the readopt loop (1.0.6), and I get a IPv6 IP, afterwards I get no traffic when trying to use that IPv6 network. It's a network on a VLAN as well.
A constructive criticism I might have is, it would be more (pro-)(con-)sumer friendly to have beta firmwares follow some path, so that ones released later contain all the previous fixes for other issues.
So, now, official released firmware (non Beta), has both issues present. Then one with fix for one issue, and a separate one for another issue (IPv6) on an older code base than both the readopt loop fix beta firmware and currently released firmware. It's an unfortunate situation.
The devices affected seem to be based on the same chipset/SDK?
Thank you @Fae for your time. Let me know if more info is needed from my side.

@Fae I have an EAP650 with the beta version running (1.0.0 Build 20221116 Rel. 42946). I see VLAN leaking at least of IPv6 NDP packets. Several devices on VLAN 30 are getting IPv6 addresses with the prefix from VLAN 20 and connections timeout because devices use the wrong address. It's just a mess :(
