Reporting back after some days of testing firmware 4.6.7.13 with my RBR850+RBS850 with Ethernet backhaul, running in AP mode with 1Gbit/sync fiber over Fritz!Box Modem.Generally I can say the switching to pink every 24h is history, the whole network is way more stable now.Nonetheless, I’m facing random complete WiFi dropouts, causing the entire network to be inaccessible for some minutes, even wired devices. Sometimes only restarting the Satellite is helping.If the satellite is off, everything is perfectly stable, so I have to assume it’s the combo of AP and satellite that make the WiFi break down.20/40Ghz coexistence is off, but that didn’t solve much. The logs are absolutely useless and don’t contain anything.I would need help to get this fixed 😞My Setup: ISP: Deutsche Glasfaser, Fiber (1GBit/s Sync), Router: Fritz!Box 5530RE, RBR850 + RBS850 (RBK853) in AP mode, Cat7 Ethernet Backhaul

Zweiklang FURRYe38 With that huge number of DHCP requests that is showing in the router log, I'm wondering if it is not overflowing memory somewhere and causing memory corruption - thereby causing the reboot. It's more of a concern that things are dropping off/reconnecting like they are, but I haven't had a chance to digest the logs yet. I see you have a mailed copy of the router logs. Is this a scheduled mail or did you go to the router logs and click on SEND. If you manually sent - the logs won't clear, but if a scheduled send, it should clear the logs, although I have found that occasionally it does not.I've found in the past that if you have a scheduled E-Mail of the logs - IF the logs fill up before the scheduled send - it will mail the log and clear. Looking at the logs briefly, it almost looks like these devices are bouncing between satellites although difficult to tell for sure. I've seen that in the past.

I did a full factory reset after installing the firmware update.The Backhaul is wired directly, no switch or wall socket in between.Distance between the two devices is approx 10m, separated by a concrete floor and a few doors.Running the satellite on wireless Backhaul shows only a “poor” connection to the AP, that’s why I have refrained from that. Connected devices had a hard time to stay connected to the network.

And you do have the host routers wifi disabled.. When the RBS was wireless did you see this same problem at the RBR other than the poor connection? Is this LAN cable between the RBR and RBS running thru the home walls or external cable? I'd be curious if you changed the RBRs transmit from 100% to 50% and see if same thing happens.

Host Router WiFi is disabled, yes. Also tried leaving it on, makes no difference.As for the wireless Backhaul causing the same issues, I would have to try again as that was before the update.The LAN cable is running external, in a separate cable channel.Will check reducing the transmit power to 50% and see if this would repeat then. Maybe the top floor wouldn’t be properly covered anymore, though. The second satellite might not get enough wireless Backhaul signal to make that up.
