I have a laptop with Kubuntu 22.04 and yesterday I could connect to the wifi without issues but today I can't, it doesn't show any networks.

I've tried some suggestions online but with no success, this is what lshw shows

user@laptop:/etc/network$ sudo lshw -C network
  *-network DISABLED     
       description: wireless interface
       product: RT5390 Wireless 802.11n 1T/1R PCIe
       producer: Ralink corp.
       . . .
       logical name: wlp3s0
       . . .
       capacities: pm msi pciexpress bus_master cap_list ethernet physical wireless
       configuration: broadcast=yes driver=rt2800pci driverversion=6.8.0-40-generic firmware=0.40 latency=0 link=no multicast=yes wireless=IEEE 802.11

Any suggestions?

EDIT: To clarify, wifi can be activated and deactivated but always says there are 0 networks. In Kubuntu there's an option to set the wifi as an access point, when I click on it it throws an error as if it couldn't reach the wifi module or something.

EDIT2: My laptop has a key to enable/disable wifi, but does nothing (and also I don't think I've pressed it) I've also tried sudo systemctl restart NetworkManager as a user suggested but didn't fix the issue.

EDIT3: Some other commands I've run that I found on the internet in case they help somehow

user@laptop:/home/user$ sudo iwlist wlp3s0 scanning
wlp3s0    Interface doesn't support scanning : Network is down

user@laptop:/home/user$ nmcli device

DEVICE      TYPE      STATE          CONNECTION

enp4s0f2    ethernet  connected      Wired connection 1 
tailscale0  tun       connected      tailscale0

wlp3s0      wifi      unavailable    --

lo          loopback  not handled    --

EDIT 3: As a user suggested in the comments, this is the output of the script to debug the networking issues https://termbin.com/2vql

EDIT 4: As stated in the comments, changing wifi.powersave to value 2 now makes it work for 1 minute, then a popup appears stating that the device is down. This is the output of nmcli device before the minute passes

user@laptop:~$ nmcli device
DEVICE      TYPE      STATE                   CONNECTION          
enp4s0f2    ethernet  connected               Wired connection 1 
wlp3s0      wifi      connected               MyWifiNetwork1       
tailscale0  tun       connected (externally)  tailscale0          
lo          loopback  unmanaged               --

and after the minute passes

user@laptop:~$ nmcli device
DEVICE      TYPE      STATE                   CONNECTION          
enp4s0f2    ethernet  connected               Wired connection 1    
tailscale0  tun       connected (externally)  tailscale0         
wlp3s0      wifi      disconnected            --     
lo          loopback  unmanaged               --

EDIT 5: This is the output of journalctl from boot until wifi disconnects https://termbin.com/ztrp

In the end I bought a cheap USB wifi dongle to fix this, and it works nicely.
