Wifi problem on LoPy4

Hi everyone. Thanks in advance to any help you can give me.

I have an LoPy4 about a week ago and it usually have an wifi connection. But yesterday I can’t find that wifi from the LoPy4 and I have no idea. Could anyone help me or explain what happen?

Hey @Rama95504,

Welcome to the forum. Could you give us some more information on any changes you have made between your last connection and the code you are using on your LoPy4. This will help us diagnose any issue.

Thanks @Gordon
I just follow Core Electronics’s tutorial on youtube from the start. It works well at first. I don’t know why but suddenly it just doesn’t work like usual. Even the gateway is not connected and I don’t make any hardware change to the LoPy4.
