I have temporary connection when I turn on the Wi-Fi. However, after a few minutes, it have no access to the Internet although the connection signal to the access point is still strong and stable. I have to turn it on and off again and again to have discrete connections. Please kindly help me with the issue. Thank you so much.

Here is some details of the setup.

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.
