I have a verizon fios G3100 router, which has (poor) wifi, and I am trying to completely replace the wifi function with the Archer AC2300.  I believe I should be able to do this by exactly following the steps in the "quickstart" to switch it to AP mode.  But once I do this, and it reboots, I can no longer  get on the AC23000's wifi network.  I did a reset and restored factory settings, and I will do it again, but I am pretty sure I've been following teh instructions properly.

Is there something else I need to do?  Help!
