No 6 GHz after hibernate/resume with AX210

[Uxorious]

I have noticed that the AX210 in my laptop doesn't want to auto-reconnect to 6 GHz after I hibernate/resume (I don't like suspending to RAM, so I hibernate instead).

OS is Windows 11 22H2 fully up to date with Windows updates.
I have tried both with the default MS drivers, and with the latest Intel drivers.

I can connect to 6 GHz just fine, and it stays connected for as long as I'm working (sitting pretty close to a Ubiquiti U6-Enterprise AP - 2.4/5/6 all on the same SSID).
But if I hibernate the machine, and wake it up again, it only connects to 5 GHz.
Disabling wifi and enabling it again makes it reconnect to 6 GHz.

Intel driver options are set to prefer 6 GHz, but that doesn't change anything. Neither does roaming aggressiveness.

Hello Uxorious,

Thank you for posting on the Intel® communities.

I am sorry you are having issues with your Intel® Wi-Fi 6E AX210. I will be glad to assist you.

In order to better assist you, please provide the following information:

• Is this the original adapter that came pre-installed in your system, or have you changed/installed a new adapter recently?
• Were you able to reconnect to the 6 GHz band after resuming from Hibernation in the past? If so, do you remember if there was any hardware change or driver/OS update that may have triggered the issue?
• Is this issue happening at home, office environment, or both?
• Have you configured the wireless adapter as recommended on the article https://www.intel.com/content/www/us/en/support/articles/000057574.html ?

Best regards,

---

No, I replaced the adapter with an AX210.

---

Were you able to reconnect to the 6 GHz band after resuming from Hibernation in the past? If so, do you remember if there was any hardware change or driver/OS update that may have triggered the issue?

---

I don't remember if that ever worked. I don't suspend that often without changing locations anyways, so I probably would not have noticed.

---

Is this issue happening at home, office environment, or both?

---

I don't have 6 GHz available at the office, so I have only seen it at home.

---

Have you configured the wireless adapter as recommended on the article https://www.intel.com/content/www/us/en/support/articles/000057574.html ?

---

Yes, those are (I think) the default settings. I noticed it with those settings, and then started setting preferred band and roaming aggressiveness to see if that would help.

As I said, this ONLY happens after resume-from-hibernate (I have not tried resume-from-sleep).
When it's resumed, and connected to 5 GHz, I can simply disconnect from the SSID and connect to it again, and it connects to 6 GHz.

Sorry, I was away for the holidays.

As I said, 6 GHz works fine - just not after resuming.

If I attach the scan file here, is it private to you guys, or can the world see it?
