Here I'll post some additional information: This problem appeared three days ago, after than an updating. My latptop is ASUS x441U, 7.7 GiB ram, Intel Core i5-7200U COU 2.50GHz x4 and 64 bits. Nontheless, I had a wired connection error three days ago and I've not been able to fix it. I've installed Ubuntu 18.04 LTS after than using Ubuntu 16.04.
