Re: This DFS channel is not allowed to use because the Radar was detected before. But I can't change

This DFS channel is not allowed to use because the Radar was detected before. But I can't change it.

The error message always displays, but I cannot make any changes to the wireless settings - it just complains about the radar.

 

That happens even when I try and disable the channel using DFS.

 

Any ideas?

Not sure what you mean by "that happens when I try and disble the channel using dfs"

DFS isn't something you can disable. You can use non-dfs channels. But if there's active radar, it isn't going to allow you to use dfs channels

I meant - I tried to disable the 5 ghz channel that was using DFS.

Simply selecting a non-DFS channel results in that error, so I thought I'd try that.

Whatever I do I get tat error message when I click on apply.

Tried a factory reset and reinstall?

It's been like it for years, through many resets ans reconfigs. Always the same.

There is radar about 5 miles up the road at an army airfield. So I am prepared to believe DFS is out of the question. My problem is, I can’t select a non dfs channel because I get the error.

do any of the 5ghz channels work?

For other access points, yes.

However, on the router neither of the 2 5ghz ssids are visible (in their factory settings). I cannot change anything on the wireless settings because I always get that error regardless of what I do. So I am stuck. I cannot try other channels.
