Hi,

On the 5ghz radio i have 2 SSIDs, and when i try to set the channel width to 160mhz, one of them gets disabled. On 80mhz they work fine. Not sure if there’s a setting i need to change, or is this a hw limitation. Please advice :slight_smile:

Set AUTO channel for 160 as any 160 option in GB needs DFS radar routine.

Make sure that you change the country code setting from Default to your actual country.

There's only a very small number of bands in 5Ghz that can actually be setup to do 160Mhz wide. You can google elsewhere for a deep discussion and explanation of why this is, and then exercise some manual choice in picking bands - but in only very strange border cases do you need to get to this level. Otherwise, set band selection to Auto as recommended. It's also worth noting that on some chipsets, the radio drivers have bugs that make them fight against manually setting the bands at 160hz.
