How to Fix a MOFI Router NOT Connecting to the Internet
If your Mofi Network router powers on but has no internet, these are the most common fixes for models like the MOFI4500-4GXeLTE V2.
1. Check the Signal LEDs
Look at the front lights:
POWER should be solid
INTERNET or LTE light should eventually come on
WIFI light should be on if wireless is enabled
If LTE/Internet lights stay off:
weak signal
SIM problem
APN settings issue
carrier blocking connection
2. Reboot Everything
Unplug router power
Remove SIM card
Wait 60 seconds
Reinsert SIM firmly
Power router back on
Wait 3–5 minutes
Many MOFI routers take awhile to reconnect to LTE.
3. Check SIM Card
Make sure:
SIM is active
SIM is inserted correctly
SIM works in another device/phone
Carrier did not suspend service
A bad or deactivated SIM is VERY common.
4. Verify APN Settings
This is one of the biggest causes.
Open browser and go to:
192.168.10.1
Default login is often:
Username: admin
Password: admin
Then:
Network
Modem
APN Settings
Common examples:
AT&T: broadband
T-Mobile: fast.t-mobile.com
Verizon: often automatic
Save settings and reboot router.
5. Factory Reset the Router
If settings are corrupted:
Leave router ON
Hold RESET button 10–15 seconds
Wait several minutes
Reconfigure Wi-Fi and APN
Sometimes MOFI routers get stuck after failed updates or bad settings.
6. Check Antennas
On the MOFI4500:
LTE antennas must be attached tightly
Wrong antenna ports can reduce signal badly
Loose antennas can cause:
low bars
disconnects
no LTE lock
7. Try a Different Location
Cellular routers are VERY sensitive to placement.
Try:
near a window
higher shelf
opposite side of house
away from TVs/electronics
Even moving it a few feet can matter.
8. Disable Band Locking
If someone forced LTE bands manually:
router may stop connecting
Inside MOFI settings:
return modem/bands to AUTO
Then reboot.
9. Check if Carrier Blocked the Device
Some carriers:
block certain IMEI numbers
detect hotspot/router usage
suspend unlimited plans
Symptoms:
signal bars but no internet
connects briefly then disconnects
Test:
place SIM in phone
see if data works there
10. Firmware Problems
If internet stopped after update:
firmware may be corrupted
You may need:
firmware reinstall
modem reset
recovery flash

Most Common Real-World Causes
Usually it ends up being:
Bad APN
Carrier issue
SIM not activated
Weak LTE signal
Corrupted settings after reboot/reset
