@Estebanc-

I see two issues.

Wifi connection stopped -. Do you have Xfinity as your internet provider? If so, your problem may have been caused by a recent update to many Xfinity-supplied routers:

Xfinity users report the router configuration needs to be switched back to b/g/n security. If you don't have access to your router settings, you may have to request Xfinity to do this for you.

5 GHz wifi not being found -  Roku Express/Express+ (not the relatively new Express 4K/4K+) and Premiere/Premiere+ are lower end units with single band Wi-Fi radios that only support the 2.4 GHz band. They, and many other devices of all sorts that are 2.4 GHz only, can't even see the 5 GHz band, !et alone connect to it. If you have one of these Roku models and a dual band router with both 2.4 and 5 GHz bands, be sure the router's 2.4 GHz band is turned on.

Within the 2.4 GHz band, Rokus support channels 1-11 as are used in North America. If your router supports 2.4 GHz channels outside this range make sure your router is set to use a channel in this range and that you aren't using an auto setting that could select channels outside this range.

What do you mean by "does not allow my password"?  Is there an error message?  What's the model number shown under Settings->System->About?  Most of the Express models only support 2.4GHz and only channels 1 through 11.
