Wi-Fi not working with a Realtek 8822BE

[Nailuj29]

I just installed Manjaro GNOME on my Lenovo Flex 14, but I can not get a Wi-Fi connection to stay connected. it connects for a few seconds then just drops the connection and refuses to allow me to reconnect to any networks; It just spins saying “No Networks”. Others seem to have had similar problems, but none of their solutions have worked for me.

My inxi -Nn output is

Network:
  Device-1: Realtek RTL8822BE 802.11a/b/g/n/ac WiFi adapter
    driver: rtw_8822be
  IF: wlp2s0 state: down mac: 90:32:4b:1c:82:51
  IF-ID-1: enp0s20f0u2 state: up speed: 425 Mbps duplex: half
    mac: 0e:80:21:b5:ca:c0

My rfkill list output is

0: ideapad_wlan: Wireless LAN
	Soft blocked: no
	Hard blocked: no
1: ideapad_bluetooth: Bluetooth

Have you tried to add either one of this to /etc/defaul/grub file, to the kernel cmdline?

pcie_aspm.policy=powersave

pcie_aspm.policy=performance

then run
sudo update-grub

That worked, thanks!
