Guest Wifi network stuck on old DNS configuration Orbi RBR750 in AP mode
Hello everyone, I'm running into a strange DNS issue on my Orbi setup and I'm hoping someone here can help. My setup: Main router: Freebox Pop (ISP router in France) Orbi RBR750 configured...

If you set a static IP address configuration for AP mode, you can set a specific or custom DNS address to use on the RBR while its in AP mode.
Static IP Address Configuration for AP Mode | NETGEAR Communities
While in AP mode any connected clients get DNS either from the custom DNS set on the RBR explicitly or if dynamically, will come from the host router up stream that is set there or automatic detected from the ISP. I believe any Guest Network side of things would also be automatic from the host router. Not sure if setting static and explicit DNS on the RBR in AP mode changes for the Guest Network side of the RBR.
If anything factory reset the RBR and setup from scratch with a ethernet PC and set up DNS there, then change to AP mode and test.

Yes, over 3 months ago the Forum software lost the ability to paste images into posts. Really annoying.
Please explain how the Freebox provides DNS information to client devices. Typically, devices issue a DHCP request and the DHCP server (Freebox) responds with a DHCP offer which includes a lot of information, including:
- The IP address offered to the device
- The IP subnet to be used (typically 255.255.255.0)
- The IP of the internet gateway (typically the LAN IP address of the router)
- The IP address of DNS servers (typically the LAN IP address of the router)
Does the Freebox tell devices to use itself to resolve DNS, or does it tell devices to use the AdGuard server?
