My wifi connection simply stopped after some error (I don't have the error). The system was unable to find a wireless connection. Wifi is accessible from my TV and smartphone.
The command iwconfig
shows: no wireless extensions
.
It also doesn't show a Wireless interface, just the Ethernet interface, even without the cable.
I already have wireless-tools installed and also wpasupplicant. Also, as my Ethernet interface shows that is by Realtek, I tried to install the driver rtl-wifi-new-dkms from the ppa hanipouspilot. The additional drivers doesn't show anything to install. I don't know if my wireless chipset is from Realtek or Intel. My processor is from Intel.
Using a connection via cable, I updated and upgraded everything in the system.
lspci -knn | grep Net -A3
terminal command so we can know which device you have and if something can be done after the mess you already did.
