🖥️ CompTIA A+ Lab 6.5 — Challenge Lab: Install a SOHO Network This lab demonstrates how to set up a Small Office/Home Office (SOHO) network from scratch, including physical connections, device configuration, and basic security measures. ________________________________________ 🧠 Key Concepts SOHO Network Overview: • A SOHO network provides internet access, wired/wireless connectivity, and security for a small number of devices. • Components include: o Modem – connects to ISP o Router – manages local network and internet sharing o Switch – expands wired connections o Access points / Wi-Fi – wireless connectivity o Computers, printers, and other endpoints CompTIA Exam Tip: Understand physical setup, IP addressing, DHCP, SSID security, and basic troubleshooting for small networks. ________________________________________ ▶️ Step 1 — Plan the Network Layout • Determine the number of wired and wireless devices. • Identify placement of modem, router, switch, and access points for optimal coverage. • Decide IP addressing scheme (DHCP vs static for specific devices). ________________________________________ ▶️ Step 2 — Connect the Modem • Connect ISP coax or DSL line to the modem. • Connect modem Ethernet output to the router’s WAN/Internet port. • Power on the modem and wait for it to synchronize with ISP. ________________________________________ ▶️ Step 3 — Configure the Router • Access the router via web interface or mobile app. • Change default admin credentials. • Configure WAN/Internet settings (DHCP, static IP, or PPPoE). • Enable DHCP server for LAN devices. • Configure wireless SSID and WPA2/WPA3 security. ________________________________________ ▶️ Step 4 — Connect Switch and Wired Devices • Connect the router’s LAN port to the switch uplink. • Connect PCs, printers, and other devices to switch ports using Ethernet cables. • Verify link lights on both switch and devices. ________________________________________ ▶️ Step 5 — Configure Wireless Devices • Connect laptops, phones, and IoT devices to the SSID using the configured password. • Confirm devices receive IP addresses from DHCP. ________________________________________ ▶️ Step 6 — Test Network Connectivity • Verify internet access from both wired and wireless devices. • Ping devices within the network to confirm LAN connectivity. • Test shared resources like printers or NAS if available. ________________________________________ ▶️ Step 7 — Secure and Document the Network • Enable router firewall and MAC filtering if needed. • Set up a guest Wi-Fi network for visitors. • Document: o Network diagram o IP addressing scheme o Device credentials and SSID info o Security measures implemented ________________________________________ ⚠️ Important Notes for CompTIA A+ Exam • Always change default admin credentials. • Use WPA2/WPA3 for wireless security. • Ensure DHCP is properly configured for local devices. • Test all devices to confirm connectivity before completing setup. • Maintain documentation for troubleshooting and auditing. ________________________________________ #CompTIAaPlus #SOHONetwork #NetworkSetup #WiFiSecurity #ITNetworking
