Orbi RBK850 in AP mode can't connect to satellite
Hi, seems that my problem is not new but I was not able to find a working solution: I'm running a Orbi RBK850 together with two RBS850 in my home network. I've done first the setup of the whole system in router mode with successfully syncing wireless both satellites, then powered off both satellites, switched the RBK to ap mode & after successfully restarting the RBK switched on the satellites. The RBK is getting his ip address now from an isc dhcp server on a RASPI, the RBS should do so as well - I've identified the related mac addresses & created reservations on my RASPI. On the RASPI I can see that the dhcp reservation is successfully been assigned to my RBK, but when restarting the satellites I can see that the satellites are pulling again & again via dhcp their ip addresses (which are acknowledged by the dhcp server but somehow maybe ignored by the satellites?). Furthermore I can do whatever I want but the satellites can't no longer sync wireless with by RBK - neither pushing the sync button on both RBK and satellites nor powering off & on the satellites has helped. Both satellites show magenta led ring colour.
Cabling the satellites to the RBK (ethernet backhaul) have synced them (blue led ring) but a few seconds later the led ring colour again switched back to magenta & the satellites were ignored by my client systems.
Does anyone else has an idea how to solve this issue? After setting up the whole system the 6th time I have no further idea...
Thank You
Hi,
the problem is solved 🙂
A simple cause had a big effect - I could see in the pfsense fw logs that outbound icmp was blocked - seems that the RBK is pinging to some cloud front systems regularly to see whether it has an internet connection. After enabling it it worked like a charm, the gui shows internet connection & I was able to sync both satellites.
Now I only have one small (not really urgent) problem left & that is that I'm getting (only on the RBK) a http 500 when connecting to the WebGUI via DNS name in the URL - using the ip address instead is working. But for this I will open another thread.
Thank You very much for Your help, really appreciated 🙂

I also set the RBR for a static IP address for AP mode on the RBR, i.e. 192.168.#.85 on mine when in AP mode. This IP address is out side of a default DHCP IP address pool I use of .100 to .200.

Are the RBS directly connected to the back of the RBR or is there a LAN switch in between?
What CAT# LAN cable are you using between the RBR and RBS? CAT6 is recommended.

It would be helpful to know:
- What ISP device is the Orbi router connected to?
- Where is the Raspberry Pi located? i.e.
- Is it "upstream" of the Orbi router? perhaps connected to the ISP router?
- Is it connected to the Orbi router?
- When in router mode, which device was supplying the WAN IP to the router?
- ISP router, or
- Pi
I agree with FURRYe38 , when switching the Orbi from router to AP mode, there is no need to power off the satellites unless the changeover is complicated. such as no Pi in router mode, then use Pi in AP mode? Maybe changing router IP subnets?
Perhaps there some confusion over LAN subnets? When in router mode, the Orbi LAN subnet must be different from the WAN iinterface subnet. i.e. if the Orbi router receives 192.168.xx.yy as its WAN address, then the LAN subnet can be any private subnet that is not 192.168.xx When in Access Point (AP) mode, the router WAN interface and all the devices attached to the LAN side are all in whatever IP subnet is being used by the upstream DHCP server.
Hi, the ISP device is a Fritzbox 7490. The RBK is connected via LAN port to a switch -> Fritzbox. Connecting the RBK via WAN port was not working and causing a flickering WAN connection. The RASPI is connected via the mentioned switch.
Regarding the satellite connection I tried the ethernet backhaul via direct connection to a LAN port on my RBK, but I‘d really prefer to have a wireless backhaul.
The RBR in AP mode has to be connected to the host router using it's WAN port while in AP mode.
What is the brand and model of the switch being used?
