Hi I recently switched my Orbi 850 back to router mode from AP mode as I have a new ISP. What i've found within a day is that the dhcp function on the Orbi 850 (+1 satellite) running V7.2.8.5_5.1.21 is incredibly flaky. We have about 80 devices at home, the majority of which are nanoleaf light bulbs (~40 or so), sonos devices and various other "smart" appliances. I've rebooted it multiple times to try and get things working, and it works for some but then other devices cannot get connected. Symptoms I've seen are: Windows PCs getting the default microsoft IP address of 169.254, which means it could not get an IP address. Devices that were connected before the reboot won't connect after. Devices showing incorrect device "names" against the respective mac address in the device list. Overall it seems to be incredibly unreliable. Anyone else experienced this?RBR850 Won’t connect to Orbi App
I opened the Orbi App (2.54.1.2) on my iPhone (iOS 26.6.1) to monitor some devices on my network and get the message "We can’t find your Orbi". My iPhone is connected to the WiFi SSID noted in my RBR850 Router. I am not having any internet connectivity problems on the 30 some items connected to the same SSID WiFi network. If I look in Network Map, My ATT Router and RBR850 Show as not connected, but my 1 RBS850 shows as connected. I note that my Router Settings show Firmware v7.2.8.2 but the latest version is v7.2.8.5. I tried to manually upload the newer firmware but I can’t seem to connect to my Router login page (10.0.0.1). Where do I go from here? I’ve had this system for 3 years and it has worked flawlessly, what could be wrong? Thanks in Advance!IPv6
Since replies have been turned off on all previous discussions regarding the IPv6 trouble introduced with version 7.2.7.15 and newer, I needed to create a new thread. Checking in on this once again, last mentions stated they were aware, were working on it, etc. I realize the 850 is old hardware but a properly working current firmware would be nice. Perhaps someone can share some insight on the delay? Thank you.Connect iot devices
Hello. I would like to know how to make my iot device (LaCrosse weather station) connect to the iot network that I have set up in my RBR850 router ? The device is already connected to the wifi but now I'd like to move it specifically to the iot network. Thank you, have a nice daySolvedRBS50 satellite connect to RBR850 network?
I have been running RBR50 + 5 satellites for a while and it have been pretty solid. i just picked up an RBR850 and 2 RBS850 satellites, but range is not quite enough for the whole house, I need an extra satellite. I did a quick ‘chatgpt’ which suggested I could use the RBS50 to extend the range, saying that particular node would be slower, but it would at least give me the coverage. Anyway, I tried a number of times to connect it, without much success. On one occasion, I thought it had worked, but the SSID was still the factory default, not the same as the main mesh network. Although I could connect to it, it’s not really a solution Am I wasting my time ? Do I need to fork out for another RBS850, or can anyone suggest other things I can try? TIASolvedPort forwarding allow other external ports on Orbi RBR850
I'm only forwarding one external port to internal port 22, however, the logs show various external ports forwarding to internal port 22. Those external ports have no entries in the "Port Forwarding / Port Triggering" section in the Orbi web admin page. Why is it allowing and how can I block? Here are some log entries (removed non-related lines): [LAN access from remote] from 183.91.14.197 port 37529 to 10.0.0.134 port 22 Monday, Jun 01,2026 16:39:42 [LAN access from remote] from 183.91.14.197 port 54174 to 10.0.0.134 port 22 Monday, Jun 01,2026 16:39:30 [LAN access from remote] from 183.91.14.197 port 3872 to 10.0.0.134 port 22 Monday, Jun 01,2026 16:39:19 [LAN access from remote] from 183.91.14.197 port 28671 to 10.0.0.134 port 22 Monday, Jun 01,2026 16:39:07 [LAN access from remote] from 183.91.14.197 port 13185 to 10.0.0.134 port 22 Monday, Jun 01,2026 16:38:54 [LAN access from remote] from 183.91.14.197 port 48296 to 10.0.0.134 port 22 Monday, Jun 01,2026 16:38:42 [LAN access from remote] from 183.91.14.197 port 24039 to 10.0.0.134 port 22 Monday, Jun 01,2026 16:38:30 [LAN access from remote] from 183.91.14.197 port 2803 to 10.0.0.134 port 22 Monday, Jun 01,2026 16:38:18 [LAN access from remote] from 183.91.14.197 port 64576 to 10.0.0.134 port 22 Monday, Jun 01,2026 16:38:06 [LAN access from remote] from 183.91.14.197 port 10676 to 10.0.0.134 port 22 Monday, Jun 01,2026 16:37:54 [LAN access from remote] from 183.91.14.197 port 45794 to 10.0.0.134 port 22 Monday, Jun 01,2026 16:37:42 [LAN access from remote] from 183.91.14.197 port 45558 to 10.0.0.134 port 22 Monday, Jun 01,2026 16:37:30SolvedRBK852 Unable to connect to admin web/app
A bit like the issue with the RBRE960, I now longer can connect to the admin ui of my RBR850 anymore, and the app doesn't seem to find it either. I suspect the issue started May 23rd, when I got a notification from the Orbi app that "Your RBR850 has been updated to the latest firmware, V7.2.8.2". I'm still able to log on to the admin web on the satelites, and they both shows version 7.2.8.2 also. I do see that 7.2.8.5 is the latest version, and has been so since december, so kind of strange that it chooses the version before it for auto upgrade. I have, as in the RBRE960 case tried to restart, power off (removed for minutes). And when plugging the power again, the power led turns green, and then I get a white blinking led around the router. After a while it stops and the router routes traffic, but no admin ui or ability to connect the app. I tried the next step, remove power and all ethernet cables for minutes, then gave it power (still without ethernet cables connected). Same bootup sequence, blinking white lights for a bit, then purple (indicating no internet). Connected the fibre, and the purple light stopped and the router was routing again. Only missing the ability to admin the router. I was thinking about upgrading to 7.2.8.5, but last I tried something like this, the admin web needed to be available, so are there any way to push the 7.2.8.5 to the router with no web admin? Or are there any suggestions how to fix otherwise, except for factory reset? I do understand that last effort may have to be a factory reset, but I'd hate for that to happen, as there will be alot of configurations to be done to get it back where it is now.
