Band lock allows you to lock the device to a specific LTE frequency band for a better performance. In some rare conditions, such as between two different cell towers, we need to lock the 4G router to works on a specific band to achieve a stable connection or faster speed.

For example, the default router IP of the EZR3x series router is 192.168.30.1.
The router IP of the EZR2x series router router is 192.168.20.1.
