For 2-3 yrs i've been been using muller wifi tether for root users to create a hotspot on my rooted droid razr. I download up to 50gig a month on the unlimited plan. Recently, I got a HTC DNA rooted it and put on the same tethering app. Now, every once in a while, the only site I can get to is google home page or google search result - nothing else. I turn the 4g off/on then I can go to maybe 1 web page before I am limited to the google home page or search results. As I write this post, it is working fine. Earlier, during peak hours, I had the problem. I think I read before google will cut you off, if they think you are a robot. Any ideas?
