I use at&t access point (netgear), and then wireless switches on my wifi router and cable modem.
These switches go over/are paired with the 4g wifi from the at&t access point.
It shares my data with my other cell phones. It basically doesnt use anything … costs an extra 20 per month. well worth it as i can reboot the main wifi stuff , and have.
I have tried about 5-6 different wireless switchs most have issues. the wemo only work in one location/network
the edimax work in multiple locations but after power outages come back off NOT in the last state (as do almost all of them, ie belkin )
Neo switches just don’t work and drop off the net and also come back Off after power outages.
The only one i Have found that works in multiple locations and also comes back in the last state( ie on if it wasx on) is the TP-link.
I also have one of these swtiches on the att access point paired with my main wifi wireless so I can rerboot it as well if need be.
The fineal think I do is run the access point without a battery on my ups as well as the smartthing hub, otherwise you cannot reboot it if it has its own battery.
hope this helps
