Fedora install on Acer Aspire 5 (AMD) doesn't do wifi

I will start with the fact that I love Fedora.

But recently I wanted a new laptop and I chose an Acer Aspire 5. Wifi did not work during the install but I foolishly figured that it would pick it up after. It did not. How do I get Fedora to see and use the wifi?

Here is the output of inxi so that you can know my system:

Thanks in advance,

We need more info about that adapter to even see what it is. Use inxi -Nxxx and lspci -nn to show the device with its chipset so we can tell which driver is needed, and if there is one available to support that exact adapter.

lspci -nn

The info shown by inxi as chip-ID, and by lspci -nn as within the square brackets on the right as [XXXX:XXXX] is the specific chipset identifier needed, as you can see by my entries above.

That initial post was not the output of inxi -Nxxx but the followup shows it. The output of lspci shows this

03:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. Device [10ec:b852] 

Although the answer is about ubuntu, I found this

And it seems the solution is to install an updated driver for that adapter.
There is no indicated driver loaded for that adapter at present.

  1. sudo dnf install git
    make a temp directory under your home directory where the rest can be done.
  2. mkdir rtl
    then cd into that directory
  3. cd rtl
    now download the driver source
  4. git clone https://github.com/HRex39/rtl8852be.git
    make sure the kernel headers are installed for compiling
  5. sudo dnf install kernel-devel kernel-header
    now to compile it
  6. cd rtl8852be
  7. make
  8. sudo make install
    which makes the module available for use
  9. sudo modprobe 8852be

If there are any errors while doing these steps then stop and fix the error before continuing.

If all this completes properly then inxi -Nxxx should now show the new module driver for that adapter.

There may be a few additional steps to make sure the new module loads when you reboot but it first needs to be loaded and tested before we go further.

I did have to do a couple of minor tweaks to get it to work. Mainly as indicated by the readme I needed to checkout the dev branch.

Thank you for knowing where to look! I am going to try the reboot now,
