Introduction
Wi-Fi is considered as one of the most required technological aspects for a modern lifestyle. As such, there are many Wi-Fi compatible devices offered in the market today that can connect to the Internet. That said, FingerTec likewise provides a variety of biometric devices which can support Wi-Fi connection such as TA700W. Some of our devices are available with Wi-Fi feature only upon request such as TA100C, TA100C-R, TA200 Plus, etc. Please have a look at the brochure below for the models that can support Wi-Fi.

However, the downside of using Wi-Fi as the communication mode is that the connection might drop unexpectedly for no obvious reason and it affects the transfer of attendance data from device to software as well as update settings into the device. Dropped Wi-Fi connections are much more common than you might think, and fortunately, solutions do exist.

Wi-Fi component:
1) Wi-Fi Module

2) Wi-Fi Antenna

3) Wi-Fi Module Holder

Process
Below are some of the most common ways to try and fix the issue.
 
1. Different Wi-Fi network or personal mobile hotspot
Connect the device to another Wi-Fi network or personal mobile hotspot and check on the result. For Wi-Fi network, make sure you are using the different IP address with the LAN connection. If not, there will be a conflict between the LAN and also your Wi-Fi. You can manually assign the IP address so that both range not same. 

For example: 

LAN : 192.168.1.201 
Wifi: 192.168.3.222
 
Please refer to the link below for your better understanding
 
2. Reset device to default factory settings
Reset the device to default factory settings and reconfigure the Wi-Fi setting and monitor the connection status. To reset the device, go to Menu > System > Reset > Press OK. A confirmation window will prompt you before the terminal is reset. Ensure that you are certain of performing the task before proceeding to avoid irreversible data loss.
 
3. Wi-Fi module
If you have any other FingerTec device with Wi-Fi feature, try to configure and connect this other device with your Wi-Fi network and compare the connection status. If the other device can work properly without any issue with Wi-Fi connection, swap the Wi-Fi module (for same model only) and test again. You can proceed to claim warranty to get a replacement unit if it is still under warranty

4. Firmware version
Please share with us (support@fingertec.com) the device info details using the tool below so we can check on the firmware version, whether it is updated or not.

 
If all the steps above still failed to solve the unstable Wi-Fi connection, kindly return to us the problematic device so our hardware team can check and verify the actual issue
 
Note: There is no specific distance that our device can support because it depends on the Wi-Fi router/modem. The Wi-Fi network basically have a range that's limited by the frequency, transmission power, antenna type, the location they're used in, and the environment.

Note: If any of the screenshots or steps in this manual are different from the current system, it is due to our continuous effort to improve our system from time to time. Please notify us at info@timeteccloud.com. We will update it as soon as possible.
