From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Solution to my Thinkpad E16 Wi-Fi Woes (bugs.launchpad.net)

I managed to fix the one biggest gripe about my Thinkpad E16: the RTL8852BE Wi-Fi controller randomly dropping out. I actually found this a few days ago, but I had forgotten where I put the file I had edited. You put a file in modprobe.d called 70-rtw89.conf. Both /etc/modprobe.d/ and /usr/lib/modprobe.d work - I used the latter, but for the sake of conventions, you should probably use the former.

You then put in these options for the rtw89 module: options rtw89_pci disable_clkreq=y disable_aspm_l1=y disable_aspm_l1ss=y

Now, my Thinkpad is a fully functional Linux laptop. I will be docking it to an 8 from my initial score of 8.5, but I'm back to liking it for now. If you apply the fix, be sure to update the firmware as well - some older distros have an old version that works but returns a lot of journalctl error on this card.

Update: What do you know! The updated firmware-realtek just went into backports!

As I have learned the hard way, it truly is.

I have 8723be, not only it randomly disconnects but also it sometimes drops to 30 KB/s requiring a reconnect and has bad signal reception even on Windows. Ethernet 4 life.

That first part sounds like software/firmware stuff like mine, but the second part almost sounds like an antenna design issue.
