[SOLVED]Wifi not working suddenly

It was working before i switched to Windows for some time and when i went back only Ethernet option is showing.

lspci -k

04:00.0 Network controller: MEDIATEK Corp. MT7922 802.11ax PCI Express Wireless Network Adapter
        Subsystem: MEDIATEK Corp. MT7922 802.11ax PCI Express Wireless Network Adapter
        Kernel modules: mt7921e

i have the network card, its been working for months. but

ip link

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eno1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN mode DEFAULT group default qlen 1000
    link/ether d8:43:ae:80:cf:7e brd ff:ff:ff:ff:ff:ff
    altname enp3s0
    altname enxd843ae80cf7e
3: enp6s0f3u1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UNKNOWN mode DEFAULT group default qlen 1000
    link/ether 96:33:da:ec:c1:66 brd ff:ff:ff:ff:ff:ff
    altname enx9633daecc166

doesn't have the entry for wifi, which was i am pretty sure wlan0. Neither does NetworkManager show it, it does however have the saved password.
and

iw dev

also results in no output.

Re: [SOLVED]Wifi not working suddenly

Reboot into Windows, disable "fast start" and then reboot twice. Sometimes Windows can render NICs inaccessible.

In BIOS? or in some Windows Settings?
