How to troubleshoot if there is no internet connection when using 4G Mobile Wi-Fi(Case 1)?

Note: This article is applied in the following situation: you can connect to the wireless of 4G Mobile Wi-Fi, but none of your devices can get internet access and you might see

the following icon on your computer.

Preparation: log in to the web interface( click here to see how to do this )----check the ‘Ip address’ in the ’status’ window.

(Note: here is an example to view the ip address via PC; choose the option ‘PC’ and you will have what you can see in a PC)

If the Ip address is not 0.0.0.0, then refer to this FAQ.

If the Ip address is 0.0.0.0, it means the 4G Mobile Wi-Fi is not connected to the internet yet. The reason can be that SIM card’s supporting BAND is not the same with this 4G Mobile Wi-Fi’s or the 4G Mobile Wi-Fi’s self-inserted APN is different from ISP’s etc.( ISP stands for the Internet Service Provider)

Solution

1: Sim card’s supporting band is not the same with the 4G Mobile Wi-Fi’s

The phenomenon can be that the sim card is not recognized by the router at all( you will see that the ‘profile list’ is ‘none’ )

On the PC:

On the phone ( go to ‘dial up’ and you will see this):

Solution: Check with your 3G/4G service provider to make sure that your SIM card supports 4G/3G/2G network.

For M7350 and M7300_V1: 4G: FDD-LTE B1/B3/B7/B8/B20 (2100/1800/2600/900/800MHz)

3G: DC-HSPA+/HSPA/UMTS B1/B8 (2100/900MHz)

2G: EDGE/GPRS/GSM Quad Band (850/900/1800/1900MHz)

For M7300_V2: 4G: FDD-LTE B1/B3/B7/B8/B20 (2100/1800/2600/900/800MHz)TDD-LTE B38/B40/B41 (2600/2300MHz)
3G: DC-HSPA+/HSPA+/HSPA/UMTS B1/B8 (2100/900MHz)
2G: EDGE/GPRS/GSM Quad Band (850/900/1800/1900MHz)

2: The 4G Mobile Wi-Fi’s self-inserted APN is different from ISP’s

APN info is inserted in the modem before you input your SIM card.

Sometimes, your ISP may change their APN without our notice.

Solution: create a connection profile by yourself.

The following info will be needed to create a profile: ‘APN type’ and ‘APN’ (from ISP),‘profile list’ ‘profile name’

(this can be something you like); ’PDP type’(ipv4 or ipv6) (decided by the ISP); ‘username’ and ‘password’ ‘Authentication type’( optional and decided by ISP)

Two ways to create a profile:

1) on the phone, go to ‘dial up’---’create’

2)on the laptop, Go to ‘‘advanced --’dial up’---’profile management’--’create’.

After you do the above troubleshooting, if still no internet access, then you may update the firmware to the latest one for a try by referring to this FAQ.
