So after some headaches I finally got my Airave working Modem -> Router -> Airave.
In this configuration should the cable from the router go to the Airave WAN or LAN port? When I go to a LAN port the mobile light constantly flashes, but I am able to login to the admin pages. When I go into the WAN port my mobile light locks up but then I can't login to the admin pages.
What is the correct configuration? And is there any way to get the Airave working behind the router and still be able to access the admin pages?
