How to Install Internet: Step-by-Step Guide (2026)

Getting internet set up at a new home can seem daunting, especially if you've never done it before. The process involves choosing a provider, selecting a plan, scheduling installation (or doing it yourself), and configuring your equipment. This step-by-step guide walks you through every stage, from initial order to your first speed test, ensuring a smooth setup experience.

Step 1: Choose Your Provider and Plan

Check which providers serve your address using our availability checker or each provider's website. Compare plans based on speed (how fast), price (monthly cost including fees), data caps (usage limits), and contract requirements. For most households, a 200-300 Mbps plan from a no-contract provider offers the best combination of performance and value. See our internet plans guide for detailed comparisons.

Step 2: Order Your Service

Once you've chosen a provider and plan, order online or call to sign up. You'll need your address (to verify service availability), a form of payment, and personal information for the account. During ordering, you'll choose between self-installation (you set it up yourself using a shipped kit) and professional installation (a technician comes to your home). Self-installation is free or minimal cost ($10-15 for the kit), while professional installation typically costs $50-100 but may be waived during promotions.

Step 3: Self-Installation Walkthrough

For self-installation (cable internet): locate the coaxial cable outlet in your home, connect the coaxial cable from the wall outlet to your modem's coax port, connect the modem's power cable and wait 5-10 minutes for it to sync (lights will stabilize), connect your router to the modem using the included ethernet cable, connect the router's power cable and wait 2-3 minutes for it to boot, find your WiFi network name (on the router's label) on your device and connect using the provided password. For fiber: the process is similar but you'll connect an ethernet cable from the ONT (the box on your wall where the fiber enters) to your router.

Step 4: Professional Installation

If professional installation is required (no existing wiring, complex setup, or if you prefer expert help): schedule the appointment when ordering, ensure someone 18+ is home during the 2-4 hour window, clear access to where cables enter your home and where you want the modem/router placed, and ask the technician to test speeds and verify the connection before they leave. Professional installation is necessary when your home has never had internet service, needs new cabling run, or requires an ONT installation for fiber.

Step 5: Verify and Optimize

Once connected, run a speed test (speedtest.net or fast.com) to verify you're getting speeds close to what your plan promises. Connect via ethernet cable for the most accurate test. Check that all your devices can connect to WiFi. If speeds are low or devices can't connect, power cycle the modem and router (unplug for 30 seconds, then reconnect). Configure your router's security settings: change the default admin password, ensure WPA3 encryption is enabled, and set a strong WiFi password. See our router setup guide for detailed configuration.

Choosing the Right Plan for Your Situation

The right internet plan depends on several factors unique to your household. Start by evaluating how many people will use the connection simultaneously during peak hours, typically evenings and weekends. Each simultaneous user adds to the bandwidth demand. A single user streaming in HD needs about 8 Mbps, while a household of five with multiple streams, gaming, and video calls may need 300-500 Mbps combined.

Beyond speed, consider the total cost of ownership over a two-year period. The advertised monthly rate is just the starting point. Add equipment rental fees ($10-15/month if you do not own your own modem and router), data cap overage risks ($10-15 per 50 GB if applicable), and post-promotional rate increases that typically add $20-40/month after the first year. A plan advertised at $50/month may actually average $75/month over two years when all costs are factored in.

Contract terms also matter significantly for your flexibility. Month-to-month plans let you switch providers, upgrade, or cancel without penalties. Contract plans may offer lower introductory rates but lock you in for 12-24 months with early termination fees if you leave. For most consumers in 2026, the flexibility of no-contract service outweighs the modest savings of a contract plan. Spectrum, AT&T Fiber, Verizon Fios, and T-Mobile all offer competitive no-contract options.

Optimizing Your Internet Experience

Getting the most from your internet connection requires attention to your home network setup, not just your ISP plan. Router placement is the single most impactful factor for Wi-Fi performance. Place your router in a central, elevated location away from walls, microwaves, and other electronic devices. Avoid closets, basements, and corners where signal must travel through multiple walls to reach your devices.

For homes larger than 1,500 square feet, a single router may not provide adequate coverage. Mesh Wi-Fi systems from manufacturers like Google Nest WiFi, Eero, and Netgear Orbi use multiple access points to create seamless whole-home coverage. These systems cost $150-400 but eliminate the dead zones and weak signals that cause frustration in larger homes. For more details, see our home networking guide.

Wired Ethernet connections always outperform Wi-Fi for speed and reliability. For stationary devices like desktop computers, gaming consoles, and smart TVs, running an Ethernet cable from your router provides the fastest and most consistent connection possible. Even with the fastest Wi-Fi 6 router, a wired connection delivers 20-50% better performance due to the elimination of wireless overhead and interference.

Quality of Service (QoS) settings on your router allow you to prioritize certain types of traffic over others. If you work from home, you can prioritize video conferencing traffic to ensure clear calls even when other household members are streaming or downloading large files. Most modern routers provide simple QoS interfaces through their mobile apps, making configuration straightforward even for non-technical users.

Troubleshooting Common Issues

When your internet is not performing as expected, systematic troubleshooting can identify and resolve most issues without a service call. Start by running a speed test at speedtest.net using a wired Ethernet connection to establish your baseline performance. If wired speeds meet your plan expectations but Wi-Fi is slow, the issue is your wireless setup rather than your ISP connection.

Power cycling your modem and router resolves a surprising number of internet issues. Unplug both devices, wait 30 seconds, plug the modem in first, wait for it to fully connect (usually 2-3 minutes), then plug in the router. This process clears cached errors and re-establishes your connection to the ISP network. Many ISPs recommend this as the first troubleshooting step for any connectivity issue.

If problems persist, check your ISP's outage map or social media accounts for reported service disruptions in your area. Large-scale outages require your provider to restore service, and individual troubleshooting will not resolve them. Knowing whether an outage is affecting your area saves time and frustration. If your area is not experiencing an outage, contact your ISP's technical support with your speed test results and troubleshooting history for faster resolution.

Tips for Getting the Best Experience

When choosing an internet plan for this purpose, prioritize reliability and consistent performance over raw peak speed. A stable 200 Mbps connection outperforms an inconsistent 500 Mbps one for virtually all household activities. Fiber internet provides the most consistent performance, followed by cable, then 5G wireless. Test your connection at different times of day to identify any peak-hour slowdowns, and use a wired ethernet connection for your most important devices.

Equipment quality matters as much as your internet plan. A modern WiFi 6 router ($80-200) delivers significantly better performance than the basic equipment most ISPs provide. If your home is larger than 1,500 square feet, a mesh WiFi system ($200-500) ensures consistent coverage throughout. Buying your own modem and router also saves $120-180/year in equipment rental fees. See our router guide and modem vs router guide for specific recommendations.

Review your internet plan annually. Prices change, new competitors enter markets, and your household's needs evolve. Many customers find that a plan that was appropriate two years ago is now either insufficient (more devices, more streaming) or more than they need (kids moved out, usage decreased). A quick annual review ensures you're getting the best value for your current situation. When your promotional pricing expires, call to negotiate rather than passively accepting the higher rate -- most customers save $10-25/month with a single phone call.
