I came home tonight and none of my devices can access the wifi on the Archer a6 v. 2. The network is visible to the devices and they purportedly connect to it, but then if I try to actually open a page on the internet, nothing.  We've tried ipads, MacBook, and Samsung.  I followed all of the troubleshooting recommendations for this but it doesn't work (change name of ssid, change channel, reboot, etc.) The lights are all green as though it should be working but it isn't. Please help! This is very frustrating!
