I need help, I can't seem to use any FTP or device connection tools like filezilla on my 5GHZ wifi. It works fine when I switch to 2GHZ wifi but not on 5GHZ. I don't know how to fix it. Nothing works, Filezilla, or chromecast. Does anyone know how to fix this? Most things suspect is cause windows 10 but I dunno for sure. I just know is annoying to keep switching to 2GHZ every time I decide to use chromecast or Filezilla when I want to use 5GHZ for the better network performance.
