Windows 11 with AX210/AX211 unable to see 6GHz network using the latest drivers.

When I started this thread, my main issue was 6GHz connectivity with two new Dell laptops. A 12th Gen Dell XPS 9520, and a 11th Gen Precision 7560. After 2 months having an open support ticket for both Dell finally said that the XPS 9520 does not support Wi-Fi 6E (6GHz), even though the AX211 adapter is capable of 6GHz, and Dell will not support it in the future. It wasn't designed/engineered correctly for 6GHz capability. Note - Dell's specifications never mention 6E (GHz) capability. Having had the laptop for over 30 days Dell said there was no way they could accept a return, so I took my grievance to the Better Business Bureau and filed a complaint. Within a week I had a return authorization.

My Precision 7560 finally had its Wi-Fi 6E capability enabled with firmware version 1.15.2. Dell's specifications did/do show 6GHz capability but lack the Wi-Fi 6E annotation which would be expected in the specifications.

So, I write all this because I still needed a new laptop to replace my XPS that I returned and decided on a Precision 5570 partly because it advertises 6E (6GHz) when you build one on their website, and even on my purchase order. Well guess what, it doesn't connect to the 6GHz network. I opened a support ticket and 28 days later Dell support replied "The limitation is actually with the Management Engine on the system (Intel ME), which doesn’t support the WiFi 6E.  It doesn’t look like there’s a way to turn it on at present." At least I was able to return the system within the 30-day return period.

If you really need 6E capability I would look elsewhere. If you're past your 30-day return window and still want to return the system, I would consider filing a complaint for false/deceptive advertising with the Better Business Bureau.

Sincere thanks for the info. That's kinda a gut punch though because we're a dell shop. Looking at my Precision 5570 it reads to me like it would support 6E.

Same here. Just got a new Precision 5570 and a Ubiquiti U6-Enterprise access point and I have been trying to use the 6 Ghz for a hour without any luck. The Precision 5570 site says "Intel Wi-Fi 6/6E (up to 6GHz) AX211" which is what I have so I would expect it to work.

Going to put in a support request with Dell and let them figure it out.

Allan - are you in Canada by chance? If so, ubiquity has not yet enabled 6E in Canada see you’ve got a change your site location to USA and then the 6 GHz network will appear. That said, it’s pretty flaky.

US. Even created a new WiFi network with a separate AP group for it with only itself, added "6e" to the SSID name so it would show up separately, and turned on only 6 GHz. Still nothing. At least it connects to the 5 GHz band at a decent speed.
