Mobile Band Lock
In some rare conditions, such as between two cell towers, we need to lock the 4G router to work on a specific band to get a stable connection or faster speed.
Supported Mobile Bands
The CAT12 mobile modem on the EZR24-012 router supports the below bands.
Before locking the band, please ensure the bands you want to use have at least a "Fair" signal reception in your area. Please refer to the signal test tutorial to check the signal strength.
| 4G FDD-LTE | 4G TDD-LTE | 3G |
|---|---|---|
Band 1/2/3/4/5/7/8/9/12/13/14/17/18/19/20/21/25/26/28/29/30/32/66 | Band 38/39/40/41 | Band 1/2/3/4/5/8/9/19 |
Lock Modes & Bands
The EZR24 firmware has integrated a web interface to lock network modes and mobile bands easily.
After accessing the router's admin page, go to "Network > Interfaces > Mobile: Edit." Click the tab "Advanced Settings."
Supported Modes are 3G and 4G. Suggest enabling both of them. Preferred Mode: Select 3G or 4G on this field. Support Bands: Pick up the 3G and 4G bands by enabling the checkbox. Signal Refresh Rate: Suggest inputting "10~30" seconds.
UTRAN is the Radio Access Network Architecture of 3G UMTS, while EUTRAN is that of the LTE.
Click the "Save & Apply" button on the bottom right corner to take effect of the above settings.
Wait 2~4 minutes until the mobile interface connects to the cellular network. If it has failed to connect to the mobile network, suggest reviewing the signal reception of the selected bands in your area.
The above-mentioned band-locking web UI is not available for the 4G-PPP protocol.
