My wifi keeps getting disconnected randomly. Once disconnected, switching it off and on from the GUI (Settings) doesn't do any good. After disconnection, turning it off says "No Wi-Fi Adapter Found" in the GUI settings. If I try to turn it on, it keeps searching for a network, and is unable to find one.

When it gets disconnected, it keeps being connected to the network (visible with the wifi symbol with a question mark) but no internet access is there.

Running sudo lshw -C network gives this:

*-network DISABLED

I've tried doing these:

sudo ifconfig wlp1s0 up; Gives SIOCSIFFLAGS: Input/output error
sudo systemctl start NetworkManager; Nothing happens
rfkill list; Gives:

0: hci0: Bluetooth
   Soft blocked: no
   Hard blocked: no
1: phy0: Wireless LAN
   Soft blocked: no
   Hard blocked: no

rfkill unblock all does nothing.

I am using this system:

Look at the network logs with the terminal command: `sudo journalctl -b 0 -u NetworkManager`. Read `man journalctl`.

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.
