Tips
Why isn't my Mobile WiFi responding?
Try restarting the device. If that doesn't work, restore the device to its factory settings.
Why can't I connect to my Mobile WiFi sometimes?
To save power, your Mobile WiFi's Wi-Fi auto off feature is designed to turn off Wi-Fi
when there haven't been connections for a while. You can press the POWER button to
turn on Wi-Fi again. Alternatively, you can disable this feature, although this might
impact battery life. Log in to the HiLink app or web interface and disable the Wi-Fi auto
off feature.
Why won't my Mobile WiFi connect to a network even though all the settings are
correct?
The PIN verification feature might be enabled. Launch HUAWEI HiLink and enter the
correct PIN.
Youcandisablethisfeatureifyoufind entering the PIN regularly inconvenient.
FromtheHiLinkapp,selectSettings and then disable the PIN verification feature.

13
Why can't I access the web interface at 192.168.8.1?
This is likely due to an IP address conflict when the Mobile WiFi assigns itself a new IP
address. Please try 192.168.9.1 in this case.
If your Mobile WiFi has an LCD screen, the new IP address of your web interface will be
displayed.
Why won't my Mobile WiFi power on?
Your battery is probably out of power.
Charge your Mobile WiFi for a while and power it back on.
Why did my Mobile WiFi power off all of a sudden?
Your Mobile WiFi may overheat when you use it continuously over a long period of time,
and thereby trigger its automated protection system. Wi-Fi will be turned off and your
Mobile WiFi will power off if this occurs.
Please ensure the device is properly ventilated and cooled before you power it on again.
