Orbi RBR750 - No internet for Win 10 PCs on main WiFi network, but guest network is fine
Windows 10 PCs (one desktop, two laptops) can see and connect to main Orbi RBR750 WiFi network, but always get "connected, no internet" -- if I turn on Orbi guest WiFi network, they connect to that no problem (but then they're on the guest subnet and can't "see" the devices on my main subnet, such as my network printer--so this is not a solution).
Other devices (including Android phones/tablets, game systems, Chromebooks, IoT devices) connect just fine. Updated drivers for all computers' WiFi adapters, uninstalled/reinstalled the adapters, made various tweaks to Win 10 network settings per some threads online, but to no avail. Those same PCs connect just fine to an older Orbi RBR50 with identical settings on the WiFi network.
Original network setup: Cable modem in bridge mode --> pfsense box --> Orbi RBR750 in AP mode.
Thought it could be issue with pfsense (DNS issue perhaps, though the pfsense config worked just fine with my RBR50 in AP mode), so I sidelined the pfsense box and put the Orbi into router mode and am experiencing same issue. Have done several factory resets on the Orbi, to no avail. On current firmware (3.2.16.6.)

First, do you have IPv6 enabled? If so, disable it and reset your Orbi and see if that fixes your issue.
Next - Since the problem seens to be specific to your Windows PCs and other devices are working fine, it's likely just a Windows networking config issue. Let's start from the beginning again and reset the Windows connection.
Press the Win key, search for "control panel"
Click on: Network and Sharing Center
Click in the left on: Changer adapter settings
Right click on the network adapter currently connected to your Orbi wireless networl, select Diagnose
This runs the Windows Network Troubleshooter. See if it helps. If you still cannot access internet, we need some more details:
Do the same as above, but for the network adapter right-click and select Status
In the Wi-Fi Status popup window press the Details button
Tell us what the info is for:
DHCP Enabled
IPv4 Address
IPv4 Subnet Mask
IPv4 DHCP Server
IPv4 DNS Server
The last two should be something like 192.168.1.1. Verify you can ping those IP addresses in a cmd shell on your Windows PC
