Sierra Rv55 password does not work

Hello.
Have 2 routers Rv55.
Have problem with both of them
First one can not login open web login interface.

Second one web interface working but password does not work.
Password correct because can connect to WIFI of router via this custom password printer on the sticker. Did reset but still same.

What the ways to solve this issues?
Routers is under warranty.

Hi @andy.manager,

Welcome to our community!

  1. For the first device, are you accessing the RV50X via a USB cable?
    If correct, do you see any interface appear like the one shown in the attached image? Please share a screenshot of the Network Adapters section in Device Manager with me.

  2. If it shows an IP like the one in the screenshot, you should be able to access https://192.168.14.31:9443/

  3. “Second one web interface working but password does not work.
    Password correct because can connect to WIFI of router via this custom password printer on the sticker. Did reset but still same.”
    → I still don’t fully understand your point here. Is it that you can’t log into the login page using the default password printed on the label? Or is it that you can’t log into Wi-fi by Wi-Fi password?
    If neither, could you please describe the issue in more detail?

Thanks,
Chau
