Hello,

I am trying to hook up a D-Link DIR-619L to ethernet in order to broadcast a new wireless internet. Ehternet passes through to computers just fine. However, when I try to connect any internet-enabled mobile device to it -- computers, a smartphone, a tablet -- they cannot connect, citing "authentication problems".

I've tried changing and checking the password. It has nothing to do with those, even when I know that the password is correct. I've also tried factory resetting it, to no avail.

Anything you can do to help would be greatly appreciated. Thank you!
