Logs keep saying this: “ah_dcd: wifi: [DFS-dcost] wifi1: Invalid channel 136” after radar signal disappears.</P> <P>I thought that once radar signals are not detected anymore, AP would come back in a matter of minuter/hours.</P> <P>&nbsp;</P> <P>Any hint?</P> <P>Regards</P> Fri, 29 May 2020 14:32:44 GMT https://community.extremenetworks.com/t5/extremewireless-wing/hard-to-return-to-dfs-channels/m-p/91973#M8788 sergi_dupe 2020-05-29T14:32:44Z https://community.extremenetworks.com/t5/extremewireless-wing/hard-to-return-to-dfs-channels/m-p/91974#M8789 <P>sergi,</P> <P>This is the WiNG forum of the Hub and so you likely won’t get any responses to this with the AP122 being an Aerohive AP.</P> <P>I’d suggest reposting your question in the ExtremeCloud IQ forum since this is where the Aerohive OS related devices would reside now.</P> Mon, 01 Jun 2020 20:38:06 GMT https://community.extremenetworks.com/t5/extremewireless-wing/hard-to-return-to-dfs-channels/m-p/91974#M8789 ckelly 2020-06-01T20:38:06Z https://community.extremenetworks.com/t5/extremewireless-wing/hard-to-return-to-dfs-channels/m-p/91975#M8790 <P>Done.
