Issue with Intel Wireless AC-9560 Adapter

[CWirt2]

We purchased 10 Dell Latitude 5500 computers. Every one of them has an issue with the Intel Wireless AC-9560 adapter. At times they will not connect to a wifi router or will connect and then lose connection. Also while connected Outlook 2016 will not update all the time. It will say "Updating InBox". I am using the latest Intel driver from Dell, version 21.50.1.1. I see there is a new driver on Intel's website, version 21.70. I have not installed the new driver. What could be causing this issue? It is happening with every one of the new Dell 5500 computers. We have several older Dell 5570/5550 computers and they work fine but they are not using the AC-9560 adapter.

The Intel Wireless AC-9560 adapter came originally pre-installed on the laptops, right? (default factory desing?).

It is hard to say what could be causing the issue, but the one that can check this better and answer properly would be Dell support, could it be either Dell's custom driver issue, integration/design issue, etc... who knows...

Since you already have latest driver from Dell, you may try on one of the laptops the driver (generic) from Intel:

Also perform basis steps: Check Windows update to install latest updates available, check for latest BIOS available on Dell website.

​I spoke to Del support and said they did not know of any issues with the Intel AC-9560 adapter.  None of our other Dell laptops with Intel wireless adapters other than the AC-9560 have this issue.
