I downloaded the tether app on my phone and it has been nothing but glitchy. I prefer using my laptop I am not a cell addict Frankly I don't see why when other companies offer different ways of controlling the home wifi that tp link is inflexible and does offer options. First of all I don't have data on my phone no plans to do so either What do you do for customers like that. The other is it was showing my router at first then it dissapppeared then the security option never showed up on the appNone of what isshown on your website screen shots is what I am seeing I have the basic tether I can check if wifi is on. We are currently experincing ping attacks shutting off both the router and the wifi. I upgradefrom the old insecure extender re650 to this one thinking it was secure. I don't have great neighbours I am not going to reread things I have already read on the net like somethe replies I have seen which are unhelpful I need help or I will go with another company altogether
