Orbi RBR350 incompatibility with Roborock S7 vaccuum
Recently purchased a Roborok S7 robot vacuum and although it said it would only connect to 2.4g networks, it connected ok to my Orbi RBR350 (plus 1 x satellite). Last week it fell off the network s...
Thanks, good to hear from a fellow user that has it working!
It is a very basic Vodafone Ultra Hub, had it for a few years.
Roborock error code is (-21012). When I try and reset the wifi on the robot, my app locates it, pre-populates with my wifi and details. Of the next 3 checks, the phone connects to the device, transfers info, but won't connect.
Sorry, very much a novice and glad of your help.
More than likely that vodafone hub has its own integrated router and it causes a double nat. Some devices don't have issues with double nat's but some do.
A double nat happens when you cascade more than 1 router.

Fixes? There’s 3 options but only use 1.
1. Put the modem/gateway in modem only/pass through mode. This disables its routing functions.
2. Leave the modem/gateway in router mode but put the Netgears IP address into its DMZ. This forwards the data to the netgear. You can either leave the modem/gateway’s wireless enabled or disabled. Just make sure its using a different wifi channel to prevent interference
3. Put the Netgear into access point mode. This disables its routing functions. Wifi/ethernet still works but it does disable some features.

Vodafone is a UK thing and most ISPs here insist on supplying modem/routers. And many of those don't have a convenient bridge (modem only) mode setting.
I went to point 3 first (didnt seem I could easily turn the VF modem into bridge only, and #2 looked a bit harder). This was easy enough and I was able to put the Orbi into AP mode.
Now when I open the app, it shows both 2.4 and 5g networks - presto!
However, still getting the same error from the Roborok when I try the wifi reset 😠 I even tried rebooting the robot but something is still blocking it.. tries to connect to it's own network, and eventually comes up with the same error code (-21012)
Glad of any further thoughts before I back out of AP mode and try your #2
