@Kevin_Z Ok bad news for me.... I've bought this router for this purpose. No way to update it with a firmware which allow dfs ?

@Kevin_Z Hi Kevin, A friend has the same router but with hardware v2.0. The channel used for his network is 108 so it should be compatible with dfs isn't ? My hardware v5.0 is not compatible with dfs...

Hello, I have a router Archer C7 (AC1750). I only use it in wifi 5GHz mode. Is it possible to force using DFS ? (in auto mode and without many network, dfs is not used) Best regards Frédéric
