not sure if this is the proper place but i found no subforum for this att gadget.
anyhow, after trying two att hotspots - mobley and prepaid ipad - i am now confident that coverage is good enough to provide a consistent cellular internet connection. i also installed a whole-house generator recently and thought i was at a good point to let go of my landline.
the att home phone and internet device has an ethernet port which i thought could be used to replace my landline after installing the internet module on my lynx l5100 security system. much to my surprise i was told by my alarm company that this won't work because it's a different internet?
has anybody here hooked up an alarm system to cellular internet? or can provide some insight why the ethernet port on the att home base would be different from one found on a cable internet network?
