If you're outside your home network's coverage area, such as at work or while commuting, use mobile internet. However, in this case, you'll need access to your provider's account on the official website, as connecting remotely via a local IP address isn't possible. To set up a local connection, turn on Wi-Fi on your phone and wait for the connection to establish.
It's important to understand the difference between connecting to the internet and connecting to a router. Even if the router's ISP settings are corrupted and the internet isn't working, accessing the device's menu (192.168.1.1 or 192.168.0.1) will still be accessible.

After entering the address, the system will request authorization data. By default, provider devices often use a combination admin/admin or admin/1234. However, on new models, especially those with technology support TR-069, the password can be unique and printed on a sticker on the bottom of the router case.
If the default combinations don't work and the sticker has worn off, you may need to reset your device to factory settings. This will return all settings, including the Wi-Fi and admin passwords, to the original values indicated on the sticker.
