Troubleshoot and resolve issues when your 5G ZTE MC888 router shows no internet connection with these easy-to-follow steps.
Please note: if some of your devices (computer, phone, laptop, tablet, etc.) can connect to the internet but one cannot, the problem might be the device and not the router.
Check the affected device
Try these troubleshooting steps on the device having problems:
Turn it off, and then on again.
Stop any downloads or programs running in the background.
Close all apps if you are using many at once.
Check it is not in flight mode.
Check that WiFi is enabled.
Switch to an ethernet cable
If your PC or laptop is connected to the ZTE MC888 via WiFi, consider switching to an ethernet cable. Ethernet cables provide a more reliable connection.
Make sure the modem is in a good place
The position of the ZTE MC888 can greatly influence the WiFi signal. Follow these tips:
Where possible, place your modem in a central location in your house, off the floor and slightly away from the wall.
Dense obstacles such as walls, floors, ceilings, hot water cylinders, and aquariums limit Wi-Fi performance and range.
To prevent interference, do not place the modem near electronic devices such as microwave ovens, cordless phones, or wireless transmitters like baby or room monitors.
Do not place the modem in an enclosed space such as a cupboard, under or behind a desk, or behind a large piece of furniture.
Check the modem's LEDs are flashing correctly
The modem's LEDs can tell you if the modem is working properly. If they are not flashing properly, you may need to redo the installation in case it was not done correctly. See 5G ZTE MC888 router lights and interface.
Check you are using the right network name and password
If the WiFi network is open for connection, it will show up under available WiFi networks on your device.
If it is not showing up, double-check that you are looking for the right name. The default name and password are on the sticker on the ZTE MC888.
If you have changed the network name or password but cannot remember them, a factory reset will restore the default name and password.
Restart the modem and complete a network power cycle
A power cycle requires both the power unit and the indoor router to be unplugged from the wall.
The units need to remain off for 3 to 5 minutes, then reconnect power and allow 3 to 5 minutes to reboot and re-establish a connection to the internet.
Check that the router LEDs are flashing correctly and that devices are functioning normally. Sometimes a simple reboot of the ZTE MC888 can fix the problem. See How to restart your 5G ZTE MC888 router.
Reset the modem to factory settings
The last step is to do a factory reset and erase all setting configurations that might be stopping the modem from connecting to the internet. See How to do a factory reset on your 5G ZTE MC888 router.
