usr/lib/modules/$(uname answer helped me out, but it wasn't enough. Sign the 8821ce.ko file yourself as per command given here kmodsign sha512 \ You also want to make sure SecureBoot is Disabled in the BIOS settings or it won't let you load the unsigned self-complied kernel module.

Open up a terminal and type the following lines (You can cut and paste if you prefer): sudo apt-get install -reinstall git dkms build-essential linux-headers-$(uname -r)Īfter this is completed successfully, you should reboot and find that your Wifi is working.

The solution is taken directly from post #4 by Praseodym: and will install a number of packages for building the wifi driver module (git, dkms, build-essential & linux-headers) and clone the git repository from tomaspinho.ĭKMS is used because it's "a system which will automatically recompile and install a kernel module when a new kernel gets installed or updated." It has, however, been reported to work just fine with Ubuntu 18.04. (Minor note: as of February 2019 tomaspinho is sadly no longer able to maintain the driver as he no longer has access to a computer with this chipset, and so a new maintainer may be needed, but the driver still works with Ubuntu 18.04 as at that time.) Over on github there is a repository with an RTL8821CE driver aimed at kernels 4.14 and above and specifically for Arch Linux with no support provided for other Linux Distros: (This question is a duplicate of Wi-Fi not working on Lenovo ThinkPad E570 (Realtek RTL8821CE) but I was pleased that we eventually found a solution so will write up what worked for Haz.)Īs far as I can tell, at the time of writing this, there is not yet a Wifi Driver for the Realtek RTL8821CE in the official Ubuntu Repositories.

I will post the journalctl entries next time it crashes because I don't have them right now.I'm trying to install drivers for my Wifi on my HP All-in-one desktop. sometimes I'm connected with low band and other times high band. I have noticed that my Network Adapter switches between these two frequencies. My router is configured for IPv4 (not IPv6), and supports channels in 2 GHz and 5 GHz band. anyway I don't think this is the problem.īut nothing was soft or hard blocked to start with so no differences.
SET failed on device wlan0 Operation not supported.īut I keep getting this error. I've tried to enable power management and then turn it off (even though it shows it is already turned off): sudo modprobe rtl8821ae sudo iwconfig wlan0 power offĮrror for wireless request "Set Power Management" (8B2C) : Tx excessive retries:0 Invalid misc:1 Missed beacon:0 Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Retry short limit:7 RTS thr=2347 B Fragment thr:off Wlan0 IEEE 802.11abgn ESSID:"Bravotelecom_9947" RTL8821AE 802.11ac PCIe Wireless Network Adapter sudo iwconfig #1 SMP Debian 3.16.7-ckt20-1+deb8u3 lspci -vnn | grep NetworkĠ4:00.0 Network controller : Realtek Semiconductor Co., Ltd. I can stay connected for hours (as long as 6 hours) and then sometimes it just crashes and doesn't work on reboot. I've been having problems with my wifi connection (rtl8821ae driver).
