Summary	0006897: Intel(R) Dual Band Wireless-AC 3165 unstable when power management turned on
Description	I am a new linux user, and I'm sure this issue has been noted here.(at least it should have been) but I can't find it if it is. I've been ALL over the internet trying to find a fix for this. Apparently a lot of people have this same issue. I have yet to find a solution. wireless card: Intel(R) Dual Band Wireless-AC 3165 problem: sometimes it reads the card and the wifi works, other times it does not. sometimes a reboot remedies the issue, sometimes it doesn't. Apparently from what I read this is a common problem with this type of card. If it reads the card and works fine for a day or two, then after a reboot it starts again. It might work for the first 3 minutes after startup, then goes down. It says its connected but isn't. after about 5 minutes it fails to show any connection at all. I get this error: failed to wake nic for hcmd Ive tried ip link set wlan0 down/up, and just about every other suggestion i could find. doesn't work. I get an input/output error. I've tried just about every thing I can find listed about this. Nothing has worked. I dual boot kali with windows 10. it's not a hardware problem, as it reads it sometimes and for a few minutes after i reboot. and the card works fine with windows. i installed the correct drivers and still the issue persists. Has anyone found a remedy for this or is this a true bug?
Steps To Reproduce	Randomly happens. Not sure how to sure-fire reproduce it.

NewUserTim 2021-01-30 01:43 reporter ~0014172	I actually figured out what the problem was. for some reason, the wifi power management is turned on. When i Turned it off i had 0 issue. So I did the following. iwconfig wlan0 wlan0 IEEE 802.11 ESSID: Mode:Managed Frequency:5.26 GHz Bit Rate=6 Mb/s Tx-Power=20 dBm Retry short limit:7 RTS thr:off Fragment thr:off Power Management:on <------- Link Quality=56/70 Signal level=-54 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:3 Missed beacon:0 Create this file, if you did not have it before. sudo nano /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf The content of the file: [connection] wifi.powersave = 2 NM_SETTING_WIRELESS_POWERSAVE_DEFAULT (0): use the default value NM_SETTING_WIRELESS_POWERSAVE_IGNORE (1): don't touch existing setting NM_SETTING_WIRELESS_POWERSAVE_DISABLE (2): disable powersave NM_SETTING_WIRELESS_POWERSAVE_ENABLE (3): enable powersave Then I restarted NetworkManager (sudo systemctl restart NetworkManager) Hope this helps someone else. I see people all over the place having my same problem. This worked for me. Not saying it will work for everyone. If there is a duplicate issue/fix I apologize. I have not seen it.
