Intel AC9260 cannot find the 160mhz wireless signal

[JGree19]

I have a netgear R7800 router and I installed the dd-wrt firmware. My PC has a intel ac9260 on it.

On the spec page of 9260 it says it supports 160mhz, but when I set the channel width of the 5Ghz wireless to VHT160, it cannot be found by the 9260, neither does VHT80. The widest width I can select for a working connection is HT40.

And in the device manager I have set the wireless channel as "auto" for both 2.4Ghz and 5Ghz. The picture below is my settings for now. I tried to change the network mode to N-only, AC/N-Mixed and AC-only but none of them worked with VHT80 or up. I am only having 400Mbps speed with this settings for now.

Thank you for the form. Can you please confirm if this is an integration? Amy C Intel Customer Support Technician Under Contract to Intel Corporation

[JGree19]

I don't know what is an integration.

[JGree19]

I looked up the difinition online and my case is an integration, the 9260 card is installed directly to the motherboard.

Sorry for the late respondence, the attachments are the reports you asked for, and I tried the driver you provided with installing it in the correct way, now the device manager shows "intel Wireless AC 9260 160Mhz" as the name, but I still couldn't search the WIFI signal when I set it to VHT80 or higher.

Here's the msinfo file, it seems I can't upload the msinfo file through attachment.

Thank you. I will update the thread as soon as possible. Amy C Intel Customer Support Technician Under Contract to Intel Corporation

Thank you for your patience. The Access Point will automatically pick 160Mhz if supported by the router, you can check more details about this matter here: https://www.intel.com/content/www/us/en/support/articles/000005799/network-and-i-o/wireless-networking.html Amy C Intel Customer Support Technician Under Contract to Intel Corporation

That doesn't solve my problem. I have set the "channel width for 5Ghz" is auto, and my network card is 9260, which the webpage says it supports the 160mhz. My router is netgear R7800 which I am sure it supports 160Mhz. But why my device couldn't recognize the 160mhz signal?

Hello JGree19, Thank you for your patience and working with me to solve your inquiry. I have sent you an e-mail to gather more information, also, I was reviewing some information about your router model and I was able to find some settings that must be enabled to have 160MHz signal. Please refer to the screenshot attached, also you can refer to the link below which has the user manual for your specific router: http://www.downloads.netgear.com/files/GDC/R7800/R7800_UM_EN.pdf * Please be aware that the content on that site is not controlled by Intel*.

Hello David,

I changed the firmware to dd-wrt which this manual does not apply to my router.

[David_V_Intel]

Hello JGree19, Thank you for your response. In this case, what I can recommend you to do is to try downloading the IT Administrator drivers for your Intel ® Wireless Adapter which you can find in the link below: https://www.intel.com/content/www/us/en/support/articles/000017246/network-and-i-o/wireless-networking.html If you are still unable to connect to the desired signal then please contact the router manufacturer for support with this. Or else, you can contact the system manufacturer so they can check to see if there is any hardware issue with the wireless adapter as well.
