Hi,

I have purchased an ax11000 router from tp link.

As advertised it should be able to transmit 160mhz wide channels on both wifi 5ghz bands.

At the moment I can only get the 5ghz 1 band to broadcast using 160mhz wide channels with DFS uni 2 channels.

5ghz band 2 is set to use auto channel and 160mhz width but always chooses  80mhz wide channels and even if I select a specifc uni 2 extended channel it still uses 80mhz.

I've tried already to manually set a channel but it doesn't make a difference. Neither does changing to 80mhz then back to 160mhz. 

Also power cycled the router to no avail 

My ax6600 router was perfectly fine with using uni 2 extended channels and broadcasting 160mhz wide channels so I know there aren't any local radar issues. In fact tomorrow I'll put it in the same spot just to prove it's not a DFS radar detection issue.

I'm not using smart connect and all my ssids are separate.

I wonder if anyone has faced this problem and solved it?

Seems another tp link reliability problem and I'm kind of regretting of choosing tp link since I moved away from Netgear.

Thanks
