I have rooted my Galaxy S3 and downloaded Wifi Tethering. Turned on my Samsung Galaxy 2 7inch tab and it does not find the tethering when I scan. So I manually loaded the SSID and passphrase. I can now see the SSID but it says its out of range. I can connect to my home wireless from my tab and it automatically discovered that network. Setting on the phone to make it discoverable or something I am missing?
