RBK753 DHCP Issue

I'm experiencing some strange issue with Orbi RBK753 setup. Orbi is setup in AP mode and I have a dnsmasq-dhcp server on the network. Intermittently, my iphone would complain that no internet is available, appears that it couldn't obtain an address from dhcp. Usually resolves within a minute or so, or as soon as I roam to a non-Orbi AP. When I look at the log of dhcp server, i see mutiple attempts with DHCPDISCOVER/DHCPOFFER but no DHCPREQUEST/DHCPACK. What might be the issue ?

When the Orbi is in AP mode, all it does is pass packets along.  So, DHCP broadcast packets just go "up the pipe".  Sounds like a configuration issue in the DHCP server.

 

By the way, Netgear has a separate forum for the new AX product line.  If you post in that forum, people who participate there may be aware of any differences between the new product and the older "original" Orbi discussed in this forum.  That new forum is here:

I love my Orbi.

Do you have an ISP modem router in your mix, and if so is it configured as a DHCP server?

What is your Orbi router connected to? 

Orbi RBK53 System/RBR50/RBS50/RBS50. + Orbi Voice RBS40V
RBK753 system/RBR750/RBS750/RBS750 + RBK853 System/RBR850/RBS850/RBS850
There's always a logical answer, if you have all the facts!

yes i have a att bgw210 connected, but its dhcp is also disabled. orbi router internet port is connected to a dumb switch which is also connected to the isp modem and a vm host where pihole(dhcp/dns server) is running on.
