[LMDE 3] Wifi disconects after a few minutes, Network Manager stops working
as stated in the title my wifi has been causing me issues across the board for the past few days. The wifi will work fine until eventually and randomly disconnecting, followed by network manager stating that my wifi is unavailable. None of my networks become discoverable. The only solution thus far has been rebooting, for some reason my wifi returns following a reboot.

One fix I've tried which seemed to have marginal success (longer period of connection) is installing the rtl8821ce driver, however I still have issues when I reboot, suspend, or still random connection drops.System:

Re: [LMDE 3] Wifi disconects after a few minutes, Network Manager stops working
Hello rkjbt,
That is not a fix, because your laptop has no device for that Realtek rtl8821ce driver. You should remove it. You have an Intel wifi card, for which the kernel module iwlwifi is the driver:One fix I've tried which seemed to have marginal success (longer period of connection) is installing the rtl8821ce driver
Can you please post the output of the following command, so that we get more information, what Intel card is built in:Device-2: Intel driver: iwlwifi v: kernel port: 3000 bus ID: 02:00.0

Hello rkjbt,
thank you for the output. You have a Intel Dual Band Wireless-AC 3168NGW [Stone Peak] (PCI ID 8086:24fb). Before we search in other directions, I don't know, if you have the most recent firmware (from July 2019) installed. Can you please check in the file manager under /lib/firmware for the file iwlwifi-3168-29.ucode?

Re: [LMDE 3] Wifi disconects after a few minutes, Network Manager stops working
I just checked and these are the only two iwlwifi-3168 files present. I assume my firmware is out of date?
iwlwifi-3168-21.ucode
iwlwifi-3168-22.ucode
iwlwifi-3168-21.ucode
iwlwifi-3168-22.ucode
Re: [LMDE 3] Wifi disconects after a few minutes, Network Manager stops working
Hello rkjbt,
the -29.ucode is the most recent file. You can download the deb package, install it by double-clicking and then reboot to see, if the new iwlwifi firmware helps to solve your issues.

Re: [LMDE 3] Wifi disconects after a few minutes, Network Manager stops working
a new firmware pack was just released. i should not have to say create timeshift snap to restore if things are bad https://git.kernel.org/pub/scm/linux/ke ... mware.git/
extract it and copy over
/lib/firmware
then in Terminal sudo update-initramfs -u -k all
after which rebootRe: [LMDE 3] Wifi disconects after a few minutes, Network Manager stops working
Hello trytip,
I'm sorry, but you haven't read the whole thread, otherwise you wouldn't have written your post.

Re: [LMDE 3] Wifi disconects after a few minutes, Network Manager stops working
in my /lib/firmware I now have iwlwifi-3168-29.ucode, I removed iwlwifi-3168-22.ucode. prior to removing .22 I was experiencing the same issues as before. Sporadic disconnections only solved by rebooting, sometimes multiple times. I will keep trying and see if removing .22 makes a difference.
