[SOLVED]Wifi or Network disables/ disappears when laptop suspends

[keen yarrow]

Wifi or Network disables/ disappears when laptop suspends as in it goes to sleep or hibernate. My only solution to get back network after this is to do a full power flush of the laptop which is just very inconvenient.

It's fairly common laptop power-management bug where the Wi-Fi device fails to re-initialize after suspend/hibernate.
Check nmcli device?

Also check lspci -k | grep -A3 -i network after suspend/hibernate.

ok I will try by intentionally putting discord in suspend mode

08:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8852CE PCIe 802.11ax Wireless Network Controller (rev 01) Subsystem: Lenovo Device 5852 Kernel driver in use: rtw89_8852ce Kernel modules: rtw89_8852ce

it seems the problem only occurs after a long suspend session instead of the laptop going to just sleep mode

here are my outputs if it can help

[vagrant valley]

Disable Wi-Fi power saving. Edit/Create /etc/modprobe.d/rtw89.conf and add to it this

options rtw89_8852ce disable_aspm=1

After that run sudo mkinitcpio -P and reboot and test.

I am fine with disabling ASPM since I keep the laptop plugged in anyways. Will report back with results
