Solved! Setup WiFi with wrong remote

Solution
If the other remote works on the TV, then the same way. If it does not work, then you can't. Check the remote control manual on pairing code for your TV model, or do the learning option if it has that. Then to go options and the WiFi section. If you can't, you can maybe get better results with a good universal remote like the Logitech Harmony, or buy a remote for your model TV off eBay from Sharp if they have it.
