We have Sprint phone service on a family plan. We have unlimited data and decent coverage, except at home. No bars.
They sent me an Airave, which is a femtocell, basically a baby cell tower in my basement. But they want me to install it between my modem+router (WRT54GL) and the outside world. I tried that, and my internet died. No good.
Reading up on the Web, I found most folks find the recommended installation does not work. They suggest plugging it into your LAN. The only consideration is if you use VOIP – some QOS may not work. Not my problem.
Some of the instructions were complicated – plug in a laptop, manually configure for the static IP, blah blah blah. I think the dude mixed up the WAN side with the extra LAN side on the Airave.
My config: Comcast -> Linksys WRT54GL (WAN)
Airave (WAN) -> Linksys (LAN)

Bingo. Airave at IP = 192.168.0.231 (via DHCP from the router in the internal network) and 5 bars on the cell phone. Made a call. Works. Sweet.
