Welcome to the Manjaro community @GypsyVO
My BeeLink SER 5 Max (AMD 5800H) has had no issues with WiFi in the 2 years since I installed Manjaro on it, so if your machine’s specifications are similar, you most likely shouldn’t need to add any special drivers.
Maybe Windows wasn’t properly shut down, and that has blocked Manjaro from accessing the WiFi? I haven’t used Windows in more than 20 years, so others here may be able to provide more advice on that aspect.
Some system info would be helpful. Please post the output of:
inxi -zv8
as per the pre-prepared instructions below:
As a new or infrequent forum user, please take some time to familiarise yourself with Forum requirements, and the many ways to use the forum to your benefit:
Update Announcements
The Update Announcements contain important information and a Known Issues and Solutions section that should generally be checked before posting a request for support.
System Information
Output of this command (formatted according to forum requirements) may be useful for those wishing to help:
inxi --filter --verbosity=8
or the short form:
inxi -zv8
Be prepared to provide more information and outputs from other commands whenever asked. It’s equally important to provide as much actionable information as possible in your first post, rather than simply indicating there is a problem.
