Orbi RBK-752 Satellite not connecting when router is in access point mode

After spending 1h 45min on the phone with Netgear Tech Support, we finally got it to work.

Here are the steps for anyone that is interested.

1) Start with RBR in Router mode (since my actual router (Ubiquiti) as a different ip address than the RBR default, I was able to connect directly to my router on the Orbi WAN port.
2) Sync the RBS with the router either hardwire or wireless

3) Make sure to wait until the RBS blue light turns off

4) If all the above went well, go to the RBR and switch to AP mode.

5) Leave your ethernet cable connected to the Orbi WAN port. The RBR will automatically change the Orbi WAN port to Orbi LAN
5) Let the RBR reboot

6) That' it !!!

Here are some gotchas:

1) If you are using the wired backhaul (preferred), you MUST be connected to the RBR switch. You CANNOT use a 3rd party switch (Cisco, Netgear, etc..) between the RBS and RBR in wired mode.

2) If you are using wireless backhaul and live in ~3000 sqf home with lots of walls, make sure the RBS is no more than 40 feet away from RBR. My RBS was constantly turning amber unless I move it closer to the RBR which kind of defeats the purpose.

I was able to run a dedicated ethernet cable from my RBR to RBS and it's working perfectly.

Hope this helps.
