What is a Small Office/Home Office (SOHO) network?
-
A network that uses one device (router) to manage all connections, combining router, modem, Ethernet switch, and Wi-Fi access point.
-
Why should the router be placed in a secure location?
-
To prevent tampering, accidental damage, and unauthorized access.
-
What is a WAN port used for in home router setup?
-
It connects the router to the service provider's cabling (fiber, DSL, or cable).
-
How do you connect a computer to a router?
-
Connect the computer to one of the router's LAN ports, usually color-coded yellow.
-
What should you do first when logging into a router's management page?
-
Change the default administrator password to a strong one.
-
What does a router's Internet Setup Wizard do?
-
It helps configure the router's connection to the service provider's network.
-
What is the purpose of a firmware update on a home router?
-
To fix security vulnerabilities and improve performance.
-
What encryption method is recommended for Wi-Fi networks?
-
WPA3 encryption is the most secure option, if supported by all devices.
-
What is the default SSID on most routers?
-
The default SSID is usually based on the router’s brand or model.
-
Why should you disable SSID broadcast?
-
It hides your network from casual users but does not secure it; encryption is still needed.
-
What is a guest network on a router?
-
A separate network that allows visitors to access the Internet without accessing the main network.
-
How can you avoid Wi-Fi interference?

-
Why is port forwarding used on a router?

To allow external devices to connect to a specific device or service on your home network.
-
What is the purpose of port triggering?
-

-
What are the security risks of leaving unused ports open on a router?
-
Unused ports can provide an entry point for unauthorized access, so they should be closed or deleted.
-
What is UPnP (Universal Plug-and-Play) used for?
-
It allows devices to automatically configure the router for necessary network access, simplifying setup.
-
What is a screened subnet (DMZ)?
-
A network segment isolated from the LAN to protect critical servers, minimizing the risk of attacks spreading to internal devices.
-
What are the security risks of enabling UPnP on a router?
-
It can be exploited by malicious actors to open ports for attacks, so it should be disabled if not needed.
