Ubuntu – WIFI interface disappeared

networkingwireless

I'm here because today, suddenly, the network interface no longer appears. When I try ifconfig -a, I get:

juanch0x@Juan-Notebook:~$ sudo ifconfig -a

Before this happened I had other network called "rename3".
EDIT:
Last time it works was before download the automatic updates from ubuntu

lspci -knn | grep Net -A2

Result

juanch0x@Juan-Notebook:~$ lspci -knn | grep Net -A2
02:00.0 Network controller [0280]: Ralink corp. RT3290 Wireless 802.11n 1T/1R PCIe [1814:3290]

SOLVED

I solved the problem reinstalling the drivers, for some reason, when i used the automatic updates, it was deleted, that was the reason of all this problem

Thanks Celtic Warrior for your help!

  • If you install custom kernel modules from source, you need to re-install them every time the kernel is upgraded.

    To avoid it, you can install the driver using DKMS.
