Why doesn't my home internet work on battery?

So TMobile internet is awesome and have no complaints there but for some reason I need to have it plugged in to an outlet or else no one can be online, this is an issue because it later has to be unplugged to let it cool or else it begins to overheat, is there something I can do to fix it?

Según el T-Mobile gateway manual :

During battery operation, neither Wi-Fi nor Ethernet connections are supported.

There are several threads on here dealing with overheating, and the use of fans.
