My iPhone 13 pro would loss the internet connection
My RBK752 and one additional RBS750 satellite system has the same issue. My iPhone 13 pro would loss the internet connection or wifi connection occasionlly after walking through/between the satellite...
After try and error all day, I finally found the cause.
# The original setting (with roaming problem): Modem --- Switch 1 --- (tagged port) ---- Switch 2 ---- Router
I used VLAN to separate WAN and LAN signal between router and modem, owing to limitation of wire and gear placement in my house
In this setting, LAN signals also walk through the tagged port, including the backhaul.
I found if the backhaul signal walk through the tagged port, it would get some problem between the router and satellites, making roaming to satellite unstable. I removed the tagged VLAN path in backhaul, setting the router and satellite wired to untagged ports in the same VLAN groups. The system is working stably now.
The same wired backhaul framework with tagged ports communication is stable on RBK50 series (Orbi AC mesh), but it could not work stably on RBK750 series (Orbi AX mesh).
Thanks to FURRYe38 , remind me of the difference between the Orbi AX and AC systems.
Ya I don't VLAN my system here. Probably why I didn't see it or don't see it.
I kind of figured something was happening at the switch level.
Not sure if the RBS are meant or support any kind of VLAN configurations between the RBR and RBS. Orbi systems are kind of particular when it comes to ethernet connected RBS. Been like this for a while. Even on Orbi AC. Mostly green ethernet and IGMP was problematic for Orbi AC back then.
Not a lot of home users use VLANs for LAN side configurations.
Glad you got it working. Please mark your thread as solved so others will know. Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.

Enjoy. 📡
The unstable disconnect issue occurred again after three days. This time I set the Orbi system (router mode) back to my original VLAN framework with wired backhaul and uncheking the 20/40 MHz conexistance (based on this article: orbi753分机掉线 - NETGEAR Communities). It becomes stable again for two days now, with slightly increased internet ping. By the way, my original VLAN wired backhaul network worked very well in the first year, with Orbi RBK752 in AP mode.
I think the new firmeware (4.6.8.2 / 4.6.8.5) is the main cause of unstablility (after my days and weeks efforts). However, back to old firmware is not my choice owing to security vulnerabilities fixes.
It is shame one Netgear and its Orbi AX system. They are expensive, overpriced and disappointed. ðŸ˜

Not yet.
I reset the router this time and did not reload the backup file.
Renew: The Wi-Fi disconnection on roaming iPhone occurred again (after unchecking the 20/40 MHz coexistance).
