Standard Login Data Table
Successful control panel login often requires factory data. These are unique to each model, but there are general standards used by the manufacturer. Below is a table of the most common combinations for various equipment series.
| Router series | IP address / Domain | Default login | Default password |
|---|---|---|---|
| Archer (C2, C5, C7, etc.) | 192.168.0.1 or tplinkwifi.net | admin | admin |
| TL-WR (840N, 740N) | 192.168.0.1 | admin | admin |

Creating a strong password and network security
The security of your home network directly depends on the complexity of the key you choose. Simple combinations like "12345678" or a birthdate can be cracked in seconds using specialized software. It's recommended to use a structure that includes uppercase and lowercase letters, numbers, and special characters.

Why does encryption type matter?
When setting up security, always select WPA2-PSK or WPA3 encryption. The older WEP standard is vulnerable and easily cracked, even by novices. WPA3 is the most modern and secure protocol supported by new devices.
Changing your password regularly, for example, every six months, significantly reduces the risk of unauthorized access. It's also worth disabling this feature. WPS in your router settings if you don't use it, as it is one of the weakest points in wireless network security.
