@Andrsouzaaa 

thank you for your reply.

It worked for a while but it doesn't work anymore.

I am waiting for the connection it tells me that I am connected but that there is no "connection to the internet"

@Pepouze76 

@Pepouze76  Ele está com a última versão de software ?

@Andrsouzaaa 

how to know?

@Pepouze76 in the Tether app you can look I'll show you.

click on the device to see relevant information. 

When you click you will see the current firmware information and the date... Notice this 

See current date of last version there 11/12/2020... Version 1.0.9 and date 11/12/2020

But I will advance it for you and bring the link here of your device, pay attention to the date of the new firmware and the date of the one that is in your device if the firmware of your device is with a date lower than what I will show you on the website of your device in question you will need to update... If it is the same, you don't need to do anything. If you have any questions, call me and I'll help you with everything you need.

Hello

I have a RE455

I managed to detect the wifi networks of my house (2.4ghz and 5ghz).

I managed to extend my signals and place the repeater in the best location.

However when I connect to the extended wifi network it informs me that there is no internet connection.

how to do ?

please.

@Andrsouzaaa 

here is the version

I noted the links to download the new version but how to install it?

@Pepouze76 download the firmware, unzip it, then access your device via the web version. when you manage to do these steps tell me to proceed.

@Pepouze76 you do not need to change the country , what I sent you is fully compatible , always pay attention to this the EU and US versions if it is EU it does not matter the country being EU it is fully compatible and not if it is also forget the ex versions ... EU V1 or EU V2 , this is important because the firmware is made for each specific model... with this information you can download without fear from the site I sent because it is pro model RE455 EU V1 also your model....
