Enabling 5GHz on AC8265 in linux

[Sadaananth]

Hi, I am bench-marking AC8265 for one of our products. I am able to bring 2.4GHz in 8265 but I am not able to bring 5GHz AP. 5GHz bands are showing no-ir and disabled. How to enable/ set 5GHz AP mode?

Hello @Sadaananth

Thank you for posting on the Intel® communities.

We noticed that you have opened an internal Web Ticket with us regarding the same wireless card model (Intel® Dual Band Wireless-AC 8265) and the same issue (bands showing no-IR and disabled). In this case, we will continue to help you through the internal Web Ticket. We will therefore close this community case to avoid duplication of efforts. Thank you.

Best regards,
