First of all, I know that I am trying to do something that is not a good idea ;) However, my situation demands it.
I am trying to set up a network with an AirPort Extreme router for both Wi-Fi and Ethernet devices (1 PC, a few MacBooks, 1 copier, 1 printer), and pipe internet into the router from a Verizon MiFi 5620L Hotspot. I cannot pull Ethernet from the hotspot, only wireless.
I attempted to pick up the wireless on a Mac mini I have, then set up internet sharing, and feed it out the Ethernet port on the mini to the AirPort Extreme router.
I had it all working (all devices connected on the AirPort Extreme network) for awhile, and then it crashed, I can't get it up again and I do not know how to set the IP ranges, etc. correctly on the Mac mini (both wireless and Ethernet connections) and the AirPort Extreme router.
Should they be totally different ranges? Is the Mac mini the router for the AirPort Extreme internet connection?
Any help appreciated. I need a fix today and for a few weeks until I get a hard line to this office.
