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 (How do I get an RT3290 wireless card to work?) to make it work on every start up.
Then suddenly it stopped working now. Now when I run
sudo lshw -C network it gives me this error.

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. 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.
