Nighthawk AXE7000 Router Changing 5G Channels by Itself
I have a Nighthawk AXE7800 tri-bank WiFi 6E router. I have set the 5G channel to 40, which is the only channel on the 5G network that is not used by other nearby routers. Several times now, without m...
The speed change to 80 Mhz bandwidth seems to have done the trick. Several days now and hasn't moved from channel 40. Thanks again for your expert help. I now know more about the intricacies of the 5G allocated bandwidth.
Channel 40 is a non-DFS channel. It's not restricted, hence the router should not change channels by itself.

What channel width are you trying to set? What channel is it moving to?
Channel 40 appears to be part of a 4 channel 80 MHz group. Some of the other channels in the group may end up being moved by the router.

The RAXE300's 5ghz band is "up to 4800mbps". That means its using 160hz wide channels. to use 160hz wide channels, it has to use dfs channels. They overlap and when it senses dfs broadcasts, it has to change off them. If you want to disable this, set your 5ghz bandwidth to "up to 2400mbps". that'll narrow it to 80hz wide channels and then you can set it on non-dfs channels so it doesn't change. Keep in mind, it'll still broadcast from channels 36-48 when 80hz wide. so even if you set it on a different channel, it still going to overlap to those others.
Ah, that is information I didn't have or know before. I do have the speed higher and it's using 160Mhz bandwidth. I'll reduce the speed (still faster than my 1 Gig internet speed). I suspect that is the issue. Appreciate the enlightenment.
Just when I thought I had fully unlocked the secrets of the allocated frequency spectrum, still more to learn.
I have changed the router speed for 5G to 2.4Gbs. Checked my WiFi scanning app and I'm now using 80Mhz bandwidth. I suspect based on now knowing the higher bandwidth would overlap into the DFS frequencies, I suspect the router channel will now behave itself and stay put. I'll let it run for a bit. Thanks again.
