WiFi isn't working 18.04

  • 772

On my 64-bit Ubuntu 18.04 WiFi isn't working - my WiFi networks are not visible to choose from. I got the following result:

$ lspci -vq | grep -i wireless -B 1 -A 5

01:00.0 Network controller: Ralink corp. RT3090 Wireless 802.11n 1T/1R PCIe
    Subsystem: Lite-On Communications Inc RT3090 Wireless 802.11n 1T/1R PCIe
    Flags: bus master, fast devsel, latency 0, IRQ 17
    Memory at fea00000 (32-bit,ran the following command  non-prefetchable) [size=64K]
    Capabilities: <access denied>
    Kernel driver in use: rt2800pci
    Kernel modules: rt2800pci

Is this a case of a missing driver? My Ethernet connection works fine.

Edit:

$ rfkill list all
0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no

It still does not see the WiFi networks.

Rebooting. This is a desktop system, not a laptop. It sits about five feet from the router.

Disconnected the internet, rebooted, ran the command, and reconnected the internet. dmesg | grep -e rt2 -e wlp > info.txt
