Wifi disconnecting repeatedly

Hello Manjaro community! Im a Linux newbie, so I barely know how to use terminal and I don't have much knowledge about how Linux works. So I've had this small problem with my wifi connection since installation, and couldn't solve it even when searching help from already closed questions.

My wifi works, but sometimes it randomly disconnects and then I'm not able to reconnect to any wifi if I don't restart my system.

Also my wifi speed is half of that it is on Windows. Usually on Windows I get 80 Mbps download and 10 Mbps upload, but on Manjaro I get 20 Mbps download and 10 Mbps upload.

I really hope someone can help me solve these issues, thanks for the replies in advance!

Under there is the output of the inxi -Fxxxz command.

Please post:

sudo dmesg | grep wl

Have you tested other kernels yet?

I would suggest testing at least 3 alternate kernels.

Is your bios up to date?

I've tested the 5.4.6.2 kernel, are there others I should try out?
I updated my bios last year, so maybe I should update it

Is that Windows system you refer to installed on the same computer, or are you comparing with Windows on a different computer?

I would recommend testing 5.5, 4.19, and 4.14.

Please edit your posts to include code tags to improve readability.

Please format any terminal output with three ``` backticks before and after, as shown in this picture:

I would start by doing the following:

Disable IPv6. There are several different ways to do this. Search the forum for directions.

Is your system fully up to date?

Make sure you reboot both your router and computer.

Have you tried deleting, then recreating your connections profile in Network Manager.

Test out Manjaro live boot disks with different DE's, or with other distros for comparison.

Have you tested it on alternate networks such as at a friends or neighbors, internet cafe for comparison.

Oh, sorry I forgot to mention about it. I'm using dualboot.

Thanks for the tip. I'll be sure to do this in future
