Study Notes

SOHO Networks

SOHO networks are small office/home office networks with a limited number of devices, typically without servers or enterprise-level switches.
SOHO networks usually consist of a single router connected to the internet, often serving as a modem, switch, and wireless access point.

Wireless Router Considerations

When selecting a router, consider the internet connection type, supported 802.11 standard, transmission range, and desired features.
Always change the default username and password on your router to enhance security.
Keep your router firmware updated to fix bugs, address vulnerabilities, and gain new features.

Router Placement

Choose a location that provides a strong signal for all devices while maintaining physical security.
Select a wireless channel that reduces conflicts with other nearby networks and devices.

Wireless Network Configuration

Connect the router to the modem using the "Internet" or WAN port.
Configure the router to use DHCP for automatic IP address assignment and settings.
Manually configure a static IP address if assigned by the ISP.
For DSL connections, configure PPPoE to use username and password authentication.
Set the SSID (network name) and optionally disable SSID broadcast for privacy.
Choose WPA2 Personal or WPA3 as the preferred authentication and encryption method.
Disable guest access unless setting up the router in a public location.

Network Address Translation (NAT)

NAT allows multiple devices to share a single public IP address.
The router creates a private LAN network with IP addresses like 192.168.0.5, associating them with the public IP address.

Security Considerations

Enable the built-in firewall on the router to protect against unauthorized access.
Close any unused ports on the network.
Use port forwarding for specific devices requiring access to certain services.
Use screened subnets for devices accessible by external users while maintaining internal network security.
Consider content filtering to block specific website types.
Implement IP filtering to control access to specific IP addresses.
Disable Universal Plug and Play (UPnP) if not needed to enhance security.
