Wifi Adapter not compatible with Fedora

Ask Fedora

Hi, I’m having an issue with my laptop with Fedora. My laptop sometimes disconnects from my Wifi (sometimes it even asks me for the password again). It doesn’t happen always, however when it happens once it keeps happening every 15-30 seconds. I asked on a forum some time ago and I remember someone told me my Wifi adapter was not compatible with Fedora, however I can’t find that post anymore. This is my Wifi chipset information:

Search on this forum for the adapter ‘RTL8852BE’ and you will find lots of posts about it.

I’ve read a couple of posts where they installed this driver, however it seems it should already be integrated in linux kernel.

$ lsmod | grep rtw89

I’ve also found this answer in another post. The file /etc/NetworkManager/conf.d/00-wifi-powersave.conf didn’t exist, so I created it and edited as recommended by the user. I don’t know if the issue is fixed yet because it happens pretty much randomly but I’ll let you know.
