Hi. For a while now I've used wireless on my Samsung Au7100 TV however today it randomly cut out. I tried connecting it to a different network, changing my hotspots password multiple times and the band, turning my TV off (shut down) and on, removing the networks from my TVs saved list all of which didn't work. It just comes up with "Incorrect Password". I do not have access to the router myself however all my other devices accept the password and connections whilst my TV constantly rejects the passwords.
