Yesterday, I updated ubuntu, before that my wifi was working properly, but after updating it is showing no wifi adapter found. When I first installed ubuntu on my laptop it had same problem but I fixed it following the steps given in this video. But this time it is not working. If anybody could help me out it would be wonderful

Please [edit] your question and add output of lspci -knn | grep Net -A3; rfkill list terminal command. – Pilot6 Oct 21 '20 at 09:02
Disable Secure Boot in BIOS. – Pilot6 Oct 21 '20 at 13:53
@Pilot6, I disabled it but it is still not working – ayush tiwari Oct 21 '20 at 14:05
Have you tried sudo apt-get install rtl8821ce-dkms ? – Raffles Oct 21 '20 at 14:46
