I am running Fedora 32 on a used HP Z420 workstation. My Internet connection worked all OK when I was using an Ethernet connection, but after I moved to an apartment that did not have an Ethernet output and had to use Wi-Fi instead, I can't get the Wi-Fi connection on the computer to work.

The problem is not in the Wi-Fi connection itself, as the Windows 10 laptop I have been using for remote work is able to connect to the Wi-Fi all OK.

I am using a TP-Link TL-WN823N USB Wi-Fi adapter plugged in to the computer's USB port. When I run lsusb it shows the adapter as: Bus 001 Device 003: ID 2357:0109 TP-Link TL-WN823N v2/v3 [Realtek RTL8192EU]

When I boot up the computer and log in to Fedora, the system is able to find the Wi-Fi network as its name shows up when I click on the network icon on the taskbar, along with several other Wi-Fi networks (that belong to other people and whose passwords I don't know). When I click on the network name, Fedora asks me for a network password. When I type it and click "Connect", nothing happens. I don't get connected and I don't even get a message about a wrong password or anything.

Here is what appears when I run dmesg:

[  622.856644] iwlwifi: unknown parameter 'wd_disable' ignored

I have read this SuperUser StackExchange post: https://superuser.com/questions/911635/wifi-authentication-times-out and tried the solution. It didn't work. It seems Fedora is ignoring the "wd_disable" parameter. It is also ignoring another parameter "bt_coex_acrive" (yes, it is really spelled "acrive" in the dmesg output, not "active") that I don't know where it comes from. It does not appear in any file in the directory /etc/modprobe.d.

I am able to type this StackExchange post because I'm currently at work in my company's office, where there is a working Internet connection.

Does anyone have an idea what is causing this and how I can fix it? I can provide more details if needed but there is a lag because I have to switch between my home computer (to diagnose the problem) and my work computer (to report it to StackExchange).

If the solution involves installing more software with dnf then I don't know how that would work as to be able to use dnf I would need an Internet connection in the first place.

Update 6 November 2021: I have installed the rtl8192eu kernel module found here: https://github.com/Mange/rtl8192eu-linux-driver That did not help. Nothing changed. The Wi-Fi adapter recognises the network but is unable to connect to it.

Here is what I found on dmesg output:
