Tools
Two jobs come up before any other setting: which address opens the admin page, and which username and password to try.
Tool
Find your router IP
The admin page lives at the default gateway, not always at 192.168.1.1. The gateway is a number your own device already knows. This page shows where to read it. A website cannot see that number for you.

Tool
Default password lookup
Filter by brand or IP. The table lists factory values that manufacturers have published for first setup. If the cell says the password is on the sticker or was created in an app, there is no shared default to try.
