Hi @odyodyodys
Thanks for posting in our business forum.
I hope you can read what is discussed in that post. It is not about the DHCP Options 66 and 67.
Please feel free to Wireshark and show me the DHCP Options 66 and 67 missing. And I'll escalate it if you can show me that. I'll also get one ER8411 from the warehouse to perform further tests on your description if you have a result for me.
But, if you are talking about the Next Server, which is discussed in that specific post you linked, and is what troubles most users, you should change the title of your post as it does not reflect the fact and topic we have here.
Next Server is scheduled in Q3. https://community.tp-link.com/en/business/forum/topic/663120?replyId=1345312
Even if there is an advanced beta, that's going to be in standalone mode.
If it is the Next Server, please stop spamming such a topic on DHCP Option 66.
