After accessing the router admin panel, you can find the "DEVICE" section on the right side of the front page. It includes most of the SIM card and mobile modem working status. Refresh the web page on the web browser to update the mobile connection status.
Mobile Modem is the model of 4G LTE modem.
IMEI Number, short of International Mobile Equipment Identity number. It's a unique serial number of the mobile modem.
SIM Status is the working status of the inserted SIM card. If it shows "Connected," we can then ignore the APN and protocol settings on the below steps.
If the "SIM status" shows an error, please refer to below step 4.4.5 to run debugging.
Mobile Operator is the provider of wireless communications services. * Usually the same as the SIM card provider.
Global Cell ID is a globally unique identifier of the current cell tower.
Signal Strength is the general grade of the received signal quality.
RSRP: The average power received from a single reference signal.
RSRQ: Indicates the quality of the received signal.
RSSI: Represents the entire received power, especially for 2G and 3G networks.
SNR: The signal-to-noise ratio of the given signal.
Go to "Network > Interfaces" to visit the interface overview page. Locate the "Mobile" interface and check the 4G internet IP address and traffic flow.
You can manually "Stop" or "Restart" the Mobile modem on the interface overview page.
Do not click the "Delete" button to erase any of the interfaces.
APN, short for Access Point Name, is the gateway to access the mobile network. In general conditions, the EZR34-012 router can use the default APN parameters prebuilt in the mobile modem to set up a connection.
Some mobile carriers use different APN parameters for the various data plans. You can configure the APN settings on the mobile interface to adapt to mobile carriers' networks.
After Accessing the router admin, go to "Network > Interfaces."
Click the "Edit" button on the row of the "Mobile" interface. APN: Input the mobile carrier's APN gateway address. PIN: 4-digit code. If you have not changed it before, leave it empty. PAP/CHAP Username: Username of the APN gateway. PAP/CHAP-Password: Password of the APN gateway. Authentication Type: Leave it as "--Please choose--" or choose PAP in most cases. IP Connection Type: Leave it as "--Please choose--" or choose IPv4 in most cases. Forbid Roaming: Leave it unselected unless you need to disable the roaming function.
Click the "Save & Apply" button on the bottom right corner to apply the new settings.
It will jump back to the interface overview page. Wait 1-2 minutes until the mobile modem reconnects to the mobile network.
If the Mobile can not connect, please try to reboot the router.
Below are examples of APN parameters. You can contact with mobile carrier's customer service to acquire the specific APN parameters of your data plan.
Here are the internet APN settings for some UK mobile phone operators.
Some carriers or data plans might not support the default Mobile-Data protocol. For example, in UK rural areas, the EE and Vodafone can only use the PPP protocol. In this case, please follow the below steps to switch the protocol to 4G-PPP.
4G-PPP, a short of the point-to-point protocol. It is a traditional data link layer communications protocol. PPP protocol has been very widely used and most flexible for interoperability with devices.
After accessing the router admin, go to "Network > Interfaces." Click the "Edit" button on the "Mobile" interface.
Under the "Common Configuration > tab of General Setup," choose "4G-PPP" on the field of "Protocol."
Click the confirm button "Switch protocol." It will jump to the 4G-PPP protocol setup page.
On the refreshed tab of "General Setup," you can use the default settings in most cases. Protocol: Now is using "4G-PPP". Modem device: Should use the device of "/dev/ttyUSB2".
Refer to the above step 4.3.3, to edit APN settings. Service Type: Choose UMTS/GPRS for UK/Europe/Asia/Africa. Choose CDMA/EVDO for the USA and Canada. Dial number: Use *99# for UK/Europe/Asia/Africa. Use *99***1# for the USA and Canada.
Click the "Save & Apply" button to apply the new protocol and APN settings.
It will jump back to the interface overview page. Wait 1-2 minutes until the mobile modem reconnects to the mobile network.
If the Mobile can not connect, please try to reboot the router.
If you are getting an error on the above step 4.4.1 and 4.4.2 and has no internet connection, please verify if you have a strong enough signal in your area (refer to step 2.2).
If the same SIM card works well on another modem or phone, please confirm it's unlocked, turn off the power and re-insert the SIM card.
