I was facing some issues with wifi disconnection. So I followed some askubuntu forum answers and solved the problem by manually installing the wifi device. But still I had to follow the first answer of this question to make it work on every start up. I had to run these two command on every start up to make make wifi network work.

sudo ifconfig eno1 up
sudo service network-manager restart

Then suddenly it stopped working now. Now when I ran sudo lshw -C network and it gives me this.

it says network UNCLAIMED. Why is that ? How can I solve that issue ?

When I run lspci it shows me my wifi adapter model as

08:00.0 Network controller: Ralink corp. RT3290 Wireless 802.11n 1T/1R PCIe

I followed this answer. But it says that it will work when secure boot is disabled. But the thing is I've already disabled secure boot and I was working fine about two hours ago.

How can I solve this? Any help would be much appreciated.
