Hi! I’m new to fedora and I’m running on a issue that I dont even know how to start solving. I have a thinkpad e490 with the wifi adapter from realtek RTL8822BE. I’ve tried fresh installing it again but when I lspci on the terminal it shows:
I think I run into a solution here the problem is that when I try to make what it’s said it shows me that there is an issue with a missing file named Error: Unable to find a match: linux-headers-5.14.10-300.fc35.x86_64 build-essential
What are you trying to build with make?
The error is straight forward. The kernel-headers package must be installed to build that package (whatever it is). If building things against the kernel you should also have the kernel-devel package installed.
You are a little (LOT) out of date with that kernel. The current kernel for fedora 35 is 5.15.13 and failing to update fedora before attempting to build anything is certain to cause problems in the future.
It is also quite possible that simply doing a sudo dnf update may get the proper driver installed for that chipset. Inxi did not display it but lspci did so it seems the driver is not installed.
I suggest you do an update, then reboot, then repeat the inxi -Nxx command to see if the device is now configured.
Another way to see what is happening with a device is by using dmesg and journalctl -b -e --priority 3 to see what errors are being logged with the current boot and looking for entries related to the device of interest…
All that indicates the driver is not loading, although it would be much better if you were to copy/paste the text into your post using the </> Preformatted text button above so it could all be parsed and not just what is visible on a single screenshot.
which indicates 2 possible drivers. rtw-8822be or rtw88-8822be and also references the rtw88 and lwfinger drivers.
I cannot verify the device 100% since you posted a screenshot, so please run lspci -vv and post (as preformatted text) the entire portion related to device 05:00.0 (the realtek wifi adapter). Also post the entire output of lshw -class network -numeric and inxi -Nzxx There is an additional part of the chipset ID I have not seen yet that will help identify that chipset within the database linked above.
I also found this as a tutorial on how to install the rtl8822be driver.
Hi @hdcpereira , Did you solve this connection issue in Fedora 35? I believe I’m having the same problem as you. I used Fedora 35 KDE. Everything was working fine until last week or so. I updated the computer (as usual) and my internet became very unstable. It stays connected but no internet, disconnecting or connecting all the time. I figured it would be some bug related to KDE and decided to switch to Fedora 35 Gnome, but the problem continued in Gnome as well. I’m thinking this bug is related to some wireless card driver or something related to the kernel, maybe.
The most curious thing about this is that before installing the Gnome version of the F35 I used the internet for a while through the live-usb itself and in this version (Fedora-Workstation-Live-x86_64-35-1.2.iso) the internet worked perfectly. The problem appeared after installing and subsequently updating the system. This further reinforces the idea that some recently updated package is causing these wireless problems. I’ll try to wait a while if an update appears that solves this problem and makes my internet work again as before. If that doesn’t happen, unfortunately I’ll have to install Debian or another version where this isn’t happening
I’m putting the print of the output of the commands
