Precision 7560 and XPS 9520 with AX210/AX211 not showing/connecting to 6GHz networks

Thank you! We have received the required details. We will work towards a resolution. In the meantime, you may also receive assistance or suggestions from the community members.

After eighteen messages back and forth with Dell so far, I'm really getting frustrated with incompetent support personnel.

So far, Dell's official response is that my systems do not support Wi-Fi 6E (6GHZ), meaning that the Precision 7560 was falsely advertised as having Wi-Fi 6E, and that the factory installed AX211 adapter in my XPS 9520 has had its 6GHz capability disabled. 

Signed up to this forum for this exact issue.  Have an opti 7090UUF with upgraded with an AX211 (originally an AX201 and purchased last year).  Was told by Intel its compatible and by dell its not.  Intel stated Dell needs to update its compliance records to support the new card. Dell has yet to do so with my issue. 

Precision 5470 with AX211 and  Precision 3260 with AX211 both do not see 6GHz ssid with windows 11. Upgraded the driver to 22.160.0.4, also downgraded to 22.45.1.1 still do not see 6GHz. 

AX 210 works fine with HP, lenovo with win 11 and upgraded driver. This is first time with AX211 and Dell combination. Not sure it is Dell issue of AX211 issue. Any thought on this?

I can't say for certain it is an issue with your adapter, however the issue with my Precision 7560 was that it was disabled in the BIOS by Dell.  I submitted a ticket on 29 June and Dell recently released BIOS version 1.15.2 on 21 September which finally enabled 6GHz.  The XPS 9520 does not, nor will not ever, support 6GHz according to Dell.

The dell specifications for your Precision 5470 clearly show Wi-Fi 6E (6Ghz) support, so I would contact Dell support.   For what it's worth, I'm again going through this with a new Precision 5570 which clearly shows Wi-Fi 6E (6Ghz) support.  

Dell maybe intentionally disabling 6GHz support on some computers until they can validate it, even though they advertise it.

Dell is known to release new Intel platform very quickly and they test it on users. Technical support on this forum is located in India (low cost). I suggest to buy Apple MBP 16 (W11 will be faster using virtualization on Apple ARM architecture than natively on Precision). In case of technical support Apple hire a lot of technicians they love what they do and have real knowledge about hardware/software eg. I spoke with a technician who was a chef in the past but his Apple product knowledge and problem solving approach was awesome. I have never met such professional approach at Dell. When Dell send us a technician to solve a battery problem he replaced a mainboard and forgot to align part of heatsink for MOSFETs. Also design flaws: in Precision 5540 there is steel bracket instead of plastic close to battery pins connector so it can cause a shortage (risk of fire) In case of Precision 7560 they also complicate assembly/disassembly process. Hopefully they fixed it in 7670. Ancient assembly process on production like in Lenovo and other brands. They even did not fix simple thing like TB charging port on the left and right side (I am using one cable not two). My collegaue from work wanted to use two ports but they changed port plug spacing LOL

Were you able to get WiFi 6E working on the Precision 5570? I just received my new company laptop, which is a Precision 5570 and it's not seeing my 6Ghz network. It's the only 6Ghz device I currently have so I was excited to test out the new WiFi.

Copying everything from my old laptop right now and when that's done I'll reboot and check the BIOS settings.

Unfortunately, I was not.   I still have a open support ticket and am being told that the next version wireless driver v22.170 due to be released by Dell on or about October 24th will enable Wi-Fi 6E.  I already tried the available Intel 22.170 driver, and it doesn't work so I'm not holding my breath that Dell's driver will work.  I'll probably be returning the system. 

Same issue with my new Precision 5570 trying to use with Netgear's Orbi WiFi 6E mesh system.  I was messing with this for a long time until I saw this thread.  Ridiculous Dell doesn't get this solved ASAP.  Fingers crossed next Monday's update that you mention does the trick.

There are several threads on this subject.  In one of those threads, where their system showed the same specs. as yours, Wi-Fi 6 only, the 6e option had been disabled.  Dell finally admitted it.

Why they do this with a capable Wi-Fi card, I can only guess, but possibly it is related to some restrictions of some country in which they also sell the unit.

I just received an email from my tech support agent.  The original engineer assigned to my 5570 case was mistaken about the issue and replied that Wi-Fi 6E (6Ghz) is not supported by the Precision 5570 due to limitations with the Intel Management system and it doesn't look like there is a way to turn it on at present.

Thanks for the update. I also have an open ticket but hadn't heard about the new driver. I'll keep looking for when it's available.
