Good day, I'm really quite confused as to what's going on. As it stands, I have internet coming into the house (obviously), and the router creates a wifi hotspot (obviously). All the devices in the house (PS3, two computers) connect to the wifi fine; and the computer I use is connected directly to the router. This is all fine. However, just as of the past week, whenever I turn the wifi on my phone (Samsung Galaxy S3), EVERY device has immediate DNS errors and the internet no longer works -- including the computer connected directly to the router, and the phone itself. Once I disable the wifi on my phone, every other device works. I've changed the wifi name, password, the channel. I pulled the battery on my phone and for a brief time, and then turned on the wifi and it worked for a brief time -- however, my roommates computer suddenly couldn't connect. Now my phone is back to disabling everything again. I am utterly baffled, and can't seem to find anyone /via google that is having this same error. Anyone, help?
