There's always an exception to good advice. Even Dell BIOS can have bugs. (Everything can have bugs.)I am never in any great rush to update, I wait for them except for Chipset and Bios, always Alienware/Dell Nvidia etc. I agree with Barman in posts #13 and #17
My wife's Dell Inspiron 3793 worked fine out of the box, but after a driver and BIOS upgrade a Macrium Reflect image backup across WiFi would disable the WiFi adapter. (Reflect File & Folder backups worked fine.) Replacing drivers with old back-level versions did no good. Even though I'm allergic to changing BIOS, I bit the bullet and downgraded to the level that came with the laptop - version 1.13.0 from Sept. 2019, I think. That fixed the problem. I then tried more current versions but all I tried - up to 1.19.0 - failed.
The problem has something to do with sending a large stream of large blocks. A Robocopy to a VeraCrypt container eventually kills the WiFi card (although it took sending 15GB of data once). Dell agrees there's a problem and it will eventually be fixed. In the mean time the laptop stays on a very old BIOS.
