WPA1 is not secure I want to keep only WPA2-AES.

IN-USE  SSID  MODE   CHAN  RATE      SIGNAL  BARS  SECURITY

I was not able to remove WPA1 but I was able to block TKIP which is not secure, by setting WPA2-AES = pairwise ccmp

sudo nmcli con modify "Wi-Fi Hot" 802-11-wireless-security.pairwise ccmp
sudo service network-manager restart

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.
