Hello @KCUMR

Thank you for posting on the Intel® communities.

We understand that you are having issues connecting to the 5Gz band using the 5GHz band using driver 22.10.0.7.

It is worth mentioning that the driver or software for your Intel® component might have been changed or replaced by the computer manufacturer and we recommend you work with your computer manufacturer before installing our driver so you don’t lose features or customizations.

Please review and set the Recommended Settings for 802.11ac Connectivity for the Intel® Wireless-AC 9260.

Also, please check the Advanced Intel® Wireless Adapter Settings and apply the following settings:

• 802.11n/ac/ax Wireless Mode or HT Mode change to > VHT mode or 802.11ac to enable 802.11ac data rates.
• Channel width change to > Auto (default). For band 5GHz, this setting uses 20/40/80/160 MHz depending on the wireless access point or router.

If the issue persists, please kindly confirm the following details:

1- It is always recommended to use the customized driver provided by your motherboard manufacturer (OEM). We checked AsRock's website*, but couldn't find any driver for the Intel® Wireless-AC 9260. Have you checked directly with your OEM AsRock* about customized drivers?

2- Is the Intel® Wireless-AC 9260 the original wireless adapter that came pre-installed in your system or did you install/integrate it?

3- Router / Access point model:

4- Have you checked if this issue happens testing only the system and the router? (no other wireless devices connected to the wireless network during this test).

5- Have you tried a different router or Access point for testing purposes? Have you rebooted your access-point, router, modem? Please provide details.

Also, please run the Intel® System Support Utility (Intel® SSU) and attach the report to this thread to gather more details about your system.

• Download the Intel® SSU and save the application on your computer
• Open the application, check the "Everything" checkbox, and click "Scan" to see the system and device information. The Intel® SSU defaults to the "Summary View" on the output screen following the scan. Click the menu where it says "Summary" to change to "Detailed View".
• To save your scan, click Next and click Save.

Best regards,

Hello KCUMR

We have not heard back from you so we will proceed to close this thread now. If you need any additional information, please submit a new question as this thread will no longer be monitored.

Our final recommendation is to contact your computer manufacturer (OEM) to check details about compatibility and wireless integration so they can provide more debugging from their side.
