Wi-Fi Connection

Why can't my CATLINK device connect to Wi-Fi?

There are several possible reasons why your CATLINK device may not be connecting to Wi-Fi. You can follow the steps below to jump to the corresponding section and find out what might be causing the issue:
1. The process gets stuck at 30% or 33%
2. The process gets stuck at 66%
3. The process gets stuck at “Common Issues”

The APP connects to the device, and the process gets stuck at 30% or 33% (Part 1)

Here are some possible reasons for the connection issue. You can go through them step by step on your own, or check with the help of our CS team: 1. The Wi-Fi signal on your phone is weak. For example, if you’re only seeing 1–2 bars of signal strength. 2. Incorrect Wi-Fi credentials, such as typos or special characters that the device cannot recognize. 3. Router restrictions, such as:

a. Not being a 2.4GHz network.
b. There are too many connected devices, exceeding the router’s limit.

If none of the above reasons apply, you can move on to Part 2 of this topic and get in touch with our CS team for further assistance.
