Have a Samsung 8000 Smart TV . When trying to enter my wireless internet password, the remote does not type on the keyboard. I know it is not that remote because I tried another Samsung remote that I paired (works on another set). I have done all the things, such as factory reset, unplugging, trying to use the SmartSansung App as a remote (will not work until it's on the same network as my iPad, and can't get it on the network since I can't type in password. Could this be a defective wifi module? When I was hard wired I didn't need a password, but I have changed internet providers and need it for their wifi setup.
