How to Determine if Your WiFi is 2.4G
Check Your Router Model:
Most routers have a label or marking next to
the model number indicating whether they
are 2.4G.
Use a Network Scanning Tool:
Install a network scanning tool on your
device, such as Fing or Network Scanner.
These tools can scan nearby networks and
display their SSID, frequency band, and
other information. This will help you
determine if your WiFi is 2.4G.
Check Your Device Settings:
Go to the settings menu on your device
and find the WiFi settings option. Here,
you can see detailed information about
the WiFi network you are connected to,
including the frequency band.
Use Third-Party Apps:
For example, "WiFi Analyzer" is a very
useful app that can show you the WiFi
signals around you, including their
frequency bands.

are correct. Double-check for any spelling
errors or misplaced characters.

2.4GHz frequency band. The device can only
connect to 2.4GHz networks.
Check Router Settings:
Some routers have restrictions such as
specific IP addresses or MAC addresses
required for connection. Check the router
settings to ensure the device is authorized
to access the network.
Use a Mobile Hotspot:
Try using another mobile phone to create a
hotspot and connect both the device and the
phone with the app to this hotspot. If the
connection is successful, it indicates that the
issue is with the network environment In this
case, consider switching to a network
environment that meets the necessary
conditions.
