Several hours ago, My laptop suddenly disconnected from the wifi. When I tried to connect again, I was surprised that my wlan0 disappeared from `iwconfig`. I wasn't updating the system at that time, and restarting the system doesn't work either. I found my wifi driver iwlwifi threw many errors in the log(errors.log): Jan 10 20:38:27 localhost kernel: [113149.852944] iwlwifi 0000:01:00.0: Error sending REPLY_SCAN_ABORT_CMD: time out after 2000ms.
