I use this one when I am away from home, not for AllSky but it seems to work well in low Cell Site coverage areas; its WiFi as very strong working well on my smartphone more than 100 feet away. I tested a cheaper one and it did not work well. This one comes with a wall wart with PoE injection supplying 25 VDC through the Ethernet connection, but I substituted my own PoE connector for use in my Van (Motor Home), the MODEM worked on 12 VDC (using less than 3 watts) from the Van without any noticeable problems. I also have a telescoping mast (Paint Pole) for mounting the MODEM high off the ground for better connectivity to distant cell sites. I bought a SIM Card for it from Amazon, created an AT&T Pre-Paid account; obtaining and configuring the SIM Card account is time consuming.
