Look up Portable Wi-Fi hotspot widget by taiseiko. Great widget that utilizes the wifi tether already in your phone. Best part is, it works with either rooted or non-rooted phones with ICS or JB. I'm using it right now on my rooted VZW GN running 4.1.1 toro v1
Thanks but ive tried this already. My laptop will connect to the hotspot but it will be limited connectivity or local only. Any idea why?
