I purchased Wifi google for the home over a month ago.. things going great.. then my sons S6 cannot/will not connect to wifi. It connects to all other wifi's (friends/neighbors/businesses) but not ours. I also have an S6 and am having no issues with connecting to wifi. What would cause it to be fine... and then not work?? I noticed that when I was on Google Wifi.. i couldnt see his phone as using the internet, which i thought was weird. But then i did a system check, and found it. Wondering if this could be why he cant get on now??
