The thing is, I really don't know what to do. I just installed Ubuntu. I have no internet connection now. I have a Ralink MT7601U Wireless Adapter. But it's not working.
lsusb detects it (I guess):
Bus 001 Device 060: ID 148f:7601 Ralink Technology, Corp. MT7601U Wireless Adapter
But nothing in that wifi icon. And also 'sudo lshw -C network' only shows Ethernet. Also in one of the post, I've read that Ubuntu 17.04 (which I have) contains it by default. If so why is it not working? Should I do something? By the way, the device was not plugged when installing Ubuntu. Is there a installing-driver-from-ubuntu-cd sort of thing??
Please help. I'm new to Ubuntu.
rfkill list all and
sudo modprobe mt7601u returns nothing. The second one asked for password, though.
EDIT: So, I've managed to install driver from a source. Now
dmesg | grep mt76 gives 3 more lines at the beginning:
usbcore: registered new interface driver mt7601u mt7601Usta: loading out-of-tree module taints kernel. mt7601Usta: module verification failed: signature and/or required key missing - tainting kernel
ra0 Ralink STA
What should I do?
