Good day.

Sorry for the delay.

What is the model number of your home router?

After the setup, have you seen the 2.4ghz and 5ghz lit up?

How long have you had the device and is it the first to set up RE200?

In case that it was the password issue, please refer to this link to check if the password of router is correct or not;

and Is there any access control or mac filtering settings on the router?

 Thank you very much.
