Did not worked!

I also installed iwlwifi driver using synaptic. Did not work!

I tried sudo apt update && sudo apt upgrade, no luck either!

My question:

Is this problem related to the Ubuntu Kernel? Is there any way that I can fix this? (I can connect to internet using Ethernet)

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
