Wifi doesn't work after waking up from suspend

harvest · January 21, 2024, 8:01pm

Hi, I’ve been trying to solve the exact same issue across multiple Linux distributions.
In short words, Wifi connection works great after booting up/restarting the system, but won’t work after waking up from suspend.
When I open the Wifi UI on GNOME, it displays all the available networks, as it should.
However, after waking from suspend it won’t display a single one.
Here are some clues and information I’ve been collecting (I use Fedora Workstation 39):

lspci -k

01:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8723DE 802.11b/g/n PCIe Adapter
	DeviceName: Realtek Wireless LAN + BT
	Subsystem: Hewlett-Packard Company Device 8319
	Kernel driver in use: rtw_8723de
	Kernel modules: rtw88_8723de

Right after restart/boot up (Wifi works fine):

rfkill

ID TYPE      DEVICE      SOFT      HARD
 0 bluetooth hci0   unblocked unblocked
 1 wlan      phy0   unblocked unblocked

ip link

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: wlo1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DORMANT group default qlen 1000
    link/ether b0:68:e6:ae:df:25 brd ff:ff:ff:ff:ff:ff
    altname wlp1s0

Suspending…*
Right after waking up (Wifi doesn’t work anymore):

rfkill

    altname wlp1s0

I’ve tried restarting NetworkManager.service, but it won’t do anything
Also, journalctl | grep -E “X.*NetworkManager” (X being today’s date) shows that NetworkManager behaves differently, here are some clues I found:

try this: add this to /etc/NetworkManager/NetworkManager.conf

wifi.scan-rand-mac-address=0

Hi, thanks for your suggestion
Tried it, rebooted, but the issue persisted

Espionage724 · May 17, 2024, 12:46am

Are you using UEFI? One idea is Fastboot being enabled and not putting the wifi card in a clean state at boot.

Another is maybe the suspend type not being supported (maybe it’s Intel Rapid Start and/or only officially does s2idle and Linux does S3); in this case adding mem_sleep_default=s2idle as a kernel option could be a workaround.

I’ve also heard and experienced many odd things with Realtek wifi on Linux; did you compile a driver for that card? Some searches show a few DKMS repos and mentions about compiling on Mint implying that it isn’t natively-supported by the kernel, and in that case I’d fully go with Realtek’s driver just being odd and possibly having other workarounds.

harvest · May 18, 2024, 2:42pm

Hi, thanks for your suggestion
I tried “s2idle” and “shallow”, both work, my wifi comes back to life correctly, but the fans stay on.
The parameter “deep” turns the fans off, but the wifi dies with this option.
Also, I didn’t compile any drivers.
I remember that a github repository (for my wifi card driver) read “if you are using a kernel version > 5.0, please use the drivers that are built in by default”
Something like that
I gonna try disabling fastboot now, thanks for your help

harvest · May 18, 2024, 2:52pm

Well, it turns out I don’t even have a fastboot option in my uefi settings

foxtrot987 · October 26, 2024, 9:50pm

I have this exact problem except I’m able to see all available Wi-Fi networks after waking from suspend too, just that I’m not able to connect to any. I’m using Fedora 41 (had the same problem in fedora 40 too), this is the output I got for the command inxi -N:

Network:
  Device-1: Intel Raptor Lake-S PCH CNVi WiFi driver: iwlwifi
  Device-2: Realtek Killer E2600 GbE driver: r8169

Please let me know if you were able to resolve it

slavicd02 · November 8, 2024, 5:35am

Has started happening since Fedora 40 upgrade here: the networks are visible, yet the card won’t connect to any.

lscpci -k

	Kernel driver in use: iwlwifi
	Kernel modules: iwlwifi

Additionally, I already have the lines:

wifi.powersave = 2

in /etc/NetworkManager/conf.d/wifi-power-save-off.conf, supposedly to turn off the wifi power save feature. Also tried the wifi.scan-rand-mac-address=0 suggestion from above without success.

dmesg yields these:

My fix for this isn’t a real solution, but it worked for my purposes:

In /etc/systemd/logind.conf I set HandleLidSwitch=ignore. This prevents the laptop from going into standby when the lid is closed.

For me I usually only close the lid when going to a meeting or if the computer is off to begin with, so I don’t need the suspend functionality.

Otherwise the reason it doesn’t work is probably because of that UEFI functionality that Linus was so upset about, where the suspend functionality is implemented by being interpreted by the operating system and was only really made to work by the hardware manufacturers on Windows.

Hope this helps someone.

LP,
Jure
