Thanks.
The > just directs the output to the wireless.txt file.
Does your wired internet work? The reason I ask is that this individual How to use the WiFi in Ubuntu 20.04 using realtek semiconductor 802.11n - DEV Community uses the rtl8188fu driver to get their wireless running and their controller is Rtl810xe which is the same as yours. I’m wondering if you can install using their steps. The driver seems to work for the Z16 (Ubuntu 20.04) kernel but it is also listed for kernel 4.15 onwards which covers Z15.
Just as an aside to consider after Aravisian’s suggestions.
