RBR 50 And backhall

It may be that the router and satellite are too far apart or there are obstacles in the path between that are affecting the backhaul channel.  Sometimes moving the satellite a few feet one way or another can improve the signal.

Some users have found the Orbi works better after a firmware update if they perform a "factory reset" on the units.  The decision is complicated by how much the user has done to customize the setup (assigning IP's to specific devices, customizing device names, etc.)  If the Orbi is relatively "stock", then a factory reset is pretty simple.

Before doing that, it might be worth getting a more precise idea of the backhaul link than "poor" or "orange".  Use a web browser to connect to http://<ip of orbi>/debug.htm and check "Enable Telnet".  Use a telnet client (Windows has one built in that can be activated from the Programs menu.  It's a Windows Feature.)  and telnet to <ip of Orbi>.  Log in with the administrative credentials "admin" and the admin password, and type

You should get something like this:

{
"mac address" : "A0:04:60:0D:96:FA",
"hop" : "1",
"bridge mac" : "A0:04:60:0D:96:FA",
"backhaul conntype" : "5GHz",
"backhaul rssi" : "-67",
"backhaul macaddress" : "A0:04:60:0D:96:FD",
"backhaul phytxrate" : "780",
"backhaul phyrxrate" : "975",
"backhaul parentmac" : "A0:04:60:1C:02:39"
}

What back haul rates do you get?
