Re: RTL8821CE 802.11ac PCIe Wireless Network Adapter

Ok, thank you so much. I hope this will end all the wifi problems I've met since moving from Win7 to Linux Mint.

Re: RTL8821CE 802.11ac PCIe Wireless Network Adapter

Thanks, Kelebek! My 5 GHz wifi is working again with full speed with your advice. After installing the package from your ppa repository I noticed a new update recommendation in the Update Manager: "rtl8821ce to version 5.5.2.1. 0ubuntu-18.04.1 - Dkms source for the realtek 8821c pcie wifi drive...

Re: RTL8821CE 802.11ac PCIe Wireless Network Adapter

Latest update to linux-firmware 1.173.15 and rtl8821ce-dkms-driver killed the 5G connection of my wifi. The 2,4 GHz connection is still working. I can live with that, but I lost more than 50% of my earlier connection speed :(
Similar problems? Correction hints?

Re: RTL8821CE 802.11ac PCIe Wireless Network Adapter

Final (hopefully) comment concerning my earlier wifi problems with Realtek RTL8821CE driver: latest update to kernel version 4.15.0-76 was again successful and my Wifi is still working fine!

Re: RTL8821CE 802.11ac PCIe Wireless Network Adapter

I just noticed a new kernel update to version 4.15.0-72 in Update Manager. After some hesitation (bad experience earlier) I decided to run it. And now I'm happy to tell that my wifi is still working fine!

Re: RTL8821CE 802.11ac PCIe Wireless Network Adapter

I just noticed a new update of rtl8821ce-dkms-driver in the Update Manager. And running it solved the problem, yippeee!
Now I'm wondering, should I skip all the kernel updates in the future?

I already ran all those commands in the same order as you advised and rebooted, but no help. I posted first back the result of last command because there seems to be a problem: ’command not found’.

Re: RTL8821CE 802.11ac PCIe Wireless Network Adapter

Sorry guys (JeremyB & kelebek333), following your recommendations did not help. Earlier the tip sent by kelebek333 (using ppa repository) fixed the problem and my wireless was fully working for several weeks. But then accepting the kernel update few days ago killed it again... which I regret now.

Re: RTL8821CE 802.11ac PCIe Wireless Network Adapter

Kernel upgrade killed my wifi again yesterday. I repeated the commands of your tip with no help. My system is 19.1 Tessa. The wifi driver disappeared also at the listing of inxi -Fxz. More tips?
