Sorry, I know there are already plenty of such posts, but I haven't find a solution in any of them.
My Router Asus GT-AC2900 with official firmware was working for about a week after I bought it. Then the problem "Your ISP's DHCP does not function correctly" occured.
1. I did a factory reset three times. Both on ASUS and modem, tried to boot them in different sequences
2. If I connect to modem ISP's huawei router, it is able to obtain a DHCP lease.
3. I tried to clone ISP's router mac to asus. Tried to obtain the lease on huawei and the connect ASUS. Tried different MAC.
4. If I connect ASUS to Huawei LAN port, ASUS is able to obtain the DHCP lease from it.
5. I tried different DHCP frequency modes. Disabled firewall, Qos, all router features, didn't help. At least features that I am aware of.
6. ISP says that they see my routers DHCPDISCOVERY request. They respond with DHCPOFFER but the packet is lost somewhere.

Questions:
1.Does anybody managed to deal with the same issue?
2. What is the best way to track where packet is lost? How can I log all incoming packets. Packets, that are dropped by iptables, that are recieved by the socket, that are recieved by dhcp daemon. Everything that could help.

im not positive but I believe in the beta changelog for 386 they mention an issue with ISP dhcp failing due to trend micro being enabled. maybe try turning that off if the issue is severe, but i do believe going forward that issue will be addressed.

Thanks for the tip. Will try.
So far looks like the problem is really in ISP or it's modem. I installed tcpdump on Asus router and I can't see any DCHPOFFER request. Will keep updating
