Sounds like SOMEone is still using the default wi-fi password.
Is it possible that disk 1 is your old Linux install? I notice that it doesn’t specify NTFS for the partition type so perhaps you’re just seeing your old EXT partition? If you’re not afraid to lose that data, run diskpart from the cmd, then type “select disk 1” then “clean”. That will wipe it of any partitions and allow you to start fresh.
Oh man. I remember this. A lot of people will have no idea about this.
