I have laptop "Lenovo s110" with Fedora 22. Wi-Fi randomly disconnects and can't autoconnect.

$ dmesg
...

And when I connect manually (choose my home Wi-Fi network and click "connect") it connects:

$ dmesg

I have no idea what to do. Please, give me at least some advice.

  • only vague advice (suffering from a lack of circumstantial evidence): are you absolutely sure that the script which does the automatic connection has the same authentication key/passphrase as you do when you type in the "manual" connection? if so, i'd next check the signal strength. i've seen this sort of behavior when the strength dips even a bit below optimum. otherwise, try this same experiment with another wifi station and see if you get the same behavior (divide and conquer your causes) – Theophrastus Jul 14 '15 at 16:36
  • Oh, it seems like I need to spend a huge amount of time on these experiments. If there are no other thoughts, I will. – Sergius Jul 14 '15 at 17:51
