5Ghz channels
Hello, I saw this topic here. But I would like understand why all upper 5Ghz channels are unavailabled for the clients. In Europe, at least in France, we can use the next channels in 80Mhz : ...

Orbi uses the DFS band for backhaul for sure. I can see that my backhaul is changing between DFS channels 100-144, which confirms that Orbi is applying the DFS regulation correctly. Seems that once Orbi detects radar signals on a certain channel it jumps to another channel, which is how DFS should work.

As mentioned, Orbi uses DFS channels for backhaul, when Radar signals are detected, Orbi will switch to other channels for backhaul.
To see the events when Orbi detects radar signals you can check this in Orbi log as follows:
- Enable Telnet in the routers debug.htm page
- Telnet to Orbi and enter the following command:
- root@RBR50:~# cat /var/radardetect.log
- You will get printout similar to this:

"No such file or directory". Looks like radar detection may be location dependent. My Orbi has no file in /var with that name, or anything close to it. (U.S.)

If you checked both in router and satellites then I guess that means no radar signals have been detected by your Orbi the past few days. I noticed that values for only the past 24 hours or so are stored.
My router has such a file but my satellite doesn’t, I guess just because the satellite is in the basement and is “protected” from radar signals.
