XPS 9520 5Ghz connection

Also, it works on 5ghz mobile hotspot or if I move next to my router. Even if I do move next to it, I have to press connect a few times before it connects. 

The 5ghz WIFI can be seen, so it's not like "oh, where is my 5ghz wifi"

You might verify what type of security you are using for the 5 GHz network.  Try setting it to WPA2/WPA3. 

Do you mean what type of security I have set up on my router? 
It's WPA2-PSK.

The setting on your router may need to show WPA2-Personal and WPA3-Personal (WPA2/WPA3) since my 5 GHz network uses WPA3-Personal.  The both setting allows it to pick which one it needs.

Check mine is also using AES not PSK but that might depend on your situation.

These are the settings I have. Looking good for me tho.

I hade the same issue. Roll back driver and 5ghz worked instantly. I believe they fixed it in the latest driver update.

I'm on this driver now: 

I had the latest one (22.150) from Intel's website. Should I install an older one? 
PS: The 22.130 is from Dell's website. 

The folks with the XPS 9520 are complaining because they cannot use the 6 GHz radio.   The AX211 card is a Wi-Fi 6e card but the specs on the system only show Wi-Fi 6.  Maybe this is all tied together.  

The bottom line is the 5 GHz radio has been around for a long time and should work normally.  The AX211 card was only released the third quarter of last year so maybe it is having a problem.

With the Insider program, I am on the 22.160.0.1 driver which may be released to the public in the near future.  Just make sure your chipset drivers are up to date.  My current system with an AX201 is on 22.140..0.1 and it has never had a problem with 5 GHz.

You might even take a look at the Advanced settings for the card in Device Manager to make sure it is set for 802.11ax and any other settings you think might be involved.

My wifi card is set for 802.11ax, even set preffered 5ghz network. 
So you've signed up for the insider program in Windows? This is the way you got the .160 driver version?

My Insider system does not have the 6 GHz option.   An advanced driver may not make a difference in your situation.  

Let me double check and get back to you about that driver, I have to reboot to get into that install.

Edit:  I have 22.150.x.x for the Wi-Fi and 22.160.x.x for the Bluetooth which were both supplied through Windows.  Beta Channel if you decide to try.  Don't go to the DEV channel or you won't be able to get back to a normal install.  

Just used that tool right now. Found 3 drivers, updated them but still the same.  
I ran out of ideas. Even removed the password for the 5ghz. 

Looks like there is no other option to try. 
Thank you very much for the replies guys. I will mark this topic as closed.
