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.
You can disable this feature if you find entering the PIN regularly
inconvenient.
From the HiLink app, select Settings and then disable the PIN
verification feature.
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.
Why won't my Mobile WiFi power on?
Your battery is probably out of power.
