About 8 months ago i rooted my phone using gb and wifi tether. It worked perfectly fine as a hotspot for my laptop and Xbox until about one month ago. I do not know why, but suddenly, after starting my tethering app, the internet would work for only about ten minutes. After that, not only would the hotspot stop working, but the internet on my phone would stop working as well. The only way to get it to start again would be rebooting my phone. I tried using Pdanet instead and then a factory reset and it still does not work, regardless of whether i try to root it or use Pdanet. Any suggestions on how to get my phone working properly again?
