Lenovo Legion Y530 wifi-card not detected on Ubuntu 18.04

Question

as the title says my problem is that the wifi card is not detected and I do not know how to solve this. Here is the output of lspci -knn | grep Net -A3; rfkill list

07:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8822BE 802.11a/b/g/n/ac WiFi adapter [10ec:b822] (rev ff)
    Kernel modules: rtw_8822be

1: ideapad_bluetooth: Bluetooth
    Soft blocked: yes
    Hard blocked: no
2: hci0: Bluetooth
    Soft blocked: yes
    Hard blocked: no

Edit: I forgot to mention that the wifi card worked fine, but suddenly it did not detect any network and then I tired to restart the network manager sudo service network-manager restart and then the adapter was not detected.

Edit2: After disabling the secure boot and following this guide the outpout of lspci -knn | grep Net -A3; rfkill list remains the same:

07:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8822BE 802.11a/b/g/n/ac WiFi adapter [10ec:b822] (rev ff)

Does this answer your question? RTL8822be driver for Ubuntu 18.04 and 20.04 — guiverc, May 05 '21 at 08:12
Unfortunately no, DKMS tree already contains: 8812au-5.6.4.2_35491.20191025 — mkr, May 05 '21 at 09:55
disable it as the kernel won't allow unsigned modules to load with it enabled — Jeremy31, May 05 '21 at 10:44
@Jeremy31 I did disable secure boot and then rebooted the device following this guide but nothing changed, I don't know if I should do anything further. — mkr, May 05 '21 at 11:06
Edit the post to include new results for lspci -knn | grep Net -A3; rfkill list — Jeremy31, May 05 '21 at 11:23
See https://askubuntu.com/a/425180/300665 and post a link to wireless script result — Jeremy31, May 05 '21 at 15:58
Here it is link, I wish I will be able to understand it too one day. @Jeremy31 — mkr, May 05 '21 at 18:56
Try sudo modprobe rtw88 and post a URL for dmesg | egrep -i 'rtl|rtw'| nc termbin.com 9999 — Jeremy31, May 05 '21 at 19:31
Hello @Jeremy31, I noticed after running the script you previously mentioned, the wifi card is detected but no there are no visible networks, anyway here is the url — mkr, May 06 '21 at 05:55
Try echo "options rtw88_pci disable_aspm=1" | sudo tee /etc/modprobe.d/rtw.conf then reboot — Jeremy31, May 06 '21 at 11:00
Nothing happened, I mean, wifi adapter is still not recognized. @Jeremy31 — mkr, May 06 '21 at 12:05
Try updating the BIOS, https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872984 comment 17 — Jeremy31, May 06 '21 at 12:08
My knowledge is limited in doing that... I noticed that the output of lspci -v is the following, could that be the issue ? — mkr, May 06 '21 at 15:38
