Checklist Items (25)

Planning

Determine your coverage needs and ISP plan before buying hardware.

•

Determine coverage area

Measure the square footage and identify dead zones in your home.

•

Check ISP speed tier

Verify the maximum download/upload speed promised by your ISP to choose appropriate equipment.

•

Choose optimal router placement

Place the router centrally, elevated, and away from thick walls or metal objects.

•

List devices that will connect

Count smartphones, laptops, smart TVs, IoT devices to ensure sufficient bandwidth.

Equipment Purchase

Select a modem-router combo or separate units based on your ISP requirements.

•

Select modem compatible with ISP

Check ISP's approved modem list; DOCSIS 3.0+ for cable, compatible ONT for fiber.

•

Select router (or mesh system) with adequate throughput

Choose a router supporting at least your ISP speed and Wi‑Fi 6 if possible.

•

Purchase Ethernet cables (Cat6 or higher)

Use Cat6 cables for wired connections to ensure gigabit speeds.

•

Get a surge protector or UPS

Protect equipment from power spikes and provide brief backup during outages.

•

Optional: Wi‑Fi extender or mesh node for large homes

Consider adding extenders if coverage gaps remain after router placement.

Modem Installation

Connect the modem to the ISP line and power it up.

•

Connect coaxial/fiber line to modem

Attach the cable from the wall outlet to the modem's port; secure the connection.

•

Plug in modem power adapter

Connect the power brick to the modem and plug into a surge-protected outlet.

•

Wait for modem to synchronize with ISP

Allow 2‑5 minutes for the modem's upstream/downstream LEDs to stabilize.

•

Verify LED indicators show online status

Check that the 'Online' or 'Internet' LED is solid; refer to modem manual for patterns.

Router Setup & Configuration

Link the modem to the router and configure wireless settings.

•

Connect modem to router WAN port

Use an Ethernet cable to link the modem's LAN port to the router's WAN/Internet port.

•

Power on router and wait for boot

Plug the router into power; allow 1‑2 minutes for it to initialize.

•

Access router admin interface via browser

Open a browser and enter the router's default IP (e.g., 192.168.1.1) to log in.

•

Update router firmware to latest version

Download the newest firmware from the manufacturer's site and apply it via admin panel.

•

Set wireless network name (SSID)

Choose a unique SSID that does not reveal personal info or router model.

•

Choose Wi‑Fi frequency band (2.4 GHz or 5 GHz)

Enable both bands if dual‑band; 2.4 GHz for range, 5 GHz for speed.

•

Select security protocol (WPA3‑Personal preferred)

If devices support it, use WPA3; otherwise fall back to WPA2‑AES.

•

Create a strong Wi‑Fi password

Use at least 12 characters with a mix of letters, numbers, and symbols.

Security, Testing & Maintenance

Finalize security measures, verify performance, and plan upkeep.

•

Change default admin username/password

Replace the factory credentials with a unique strong password to prevent unauthorized access.

•

Disable WPS and UPnP if not needed

Turn off Wi‑Fi Protected Setup and Universal Plug‑and‑Play to reduce attack surface.

•

Run a speed test on connected devices

Use a reliable speed test service to confirm you receive your ISP‑advertised speeds.

•

Schedule monthly firmware check and reboot

Set a calendar reminder to check for updates and reboot the router to clear memory.
