What Do I Need to Set Up Wi-Fi?
To set up WiFi at home, you need two things: a working internet connection (fiber, cable, or DSL) and Wi‑Fi equipment.
Most internet providers give you a modem-router combo, but if it’s just a modem, you’ll need to connect a Wi‑Fi router yourself. For larger homes or spaces with multiple floors, a mesh system is the best way to keep your signal strong in every room.
When buying Wi‑Fi gear in 2025, look for support for modern standards. Wi‑Fi 6 and 6E are great for improving speed and stability. Wi‑Fi 7 (802.11be) is the newest and fastest option — it adds the 6 GHz band for less interference and smoother performance. If you're setting up a new network, Wi‑Fi 6 is the minimum you should aim for, and Wi‑Fi 7 is the most future-proof choice.
Set Up Your Internet and Router
There are many different types of wireless routers, from inexpensive home routers designed for casual use to feature-packed gaming routers with multiple antennas and state-of-the-art technologies. The good news is that the WiFi setup process is virtually always the same.
Step 1
Connect modem ↔ router. Unplug the modem’s power, connect the router’s WAN/Internet port to the modem with an Ethernet cable, then power both back on. Wait for the router’s Internet light to go solid.
Step 2
Log into the router. In a browser, enter the router’s default IP address (commonly 192.168.0.1 / 192.168.1.1 and 192.168.2.1).
Use the admin credentials from the label or manual and create your own strong admin password.
Step 4
Update firmware. In the router UI or app, install the latest firmware for security fixes and performance improvements.
Where Should I Place My WiFi Router (or Mesh Nodes)?
Besides proper how to set up WiFi, the success of your Wi-Fi network also depends on where you place the equipment. Even the fastest router won’t perform well if it’s hidden in a corner or blocked by obstacles. As a general rule, position your wireless router as close to the center of your home as possible so the signal can spread evenly in all directions.
It’s just as important to keep the router away from thick walls, heavy furniture, or large electronic devices like microwaves and TVs, which can cause interference and weaken your connection.
If you’re using mesh, put nodes one or two rooms apart with line‑of‑sight where possible; avoid stacking them in the same room.
Check and Optimize Wi-Fi Coverage
Now that your router is configured and optimally placed, the next step is to verify how well your Wi-Fi signal actually covers your home — and make any necessary adjustments.
Open NetSpot → switch to Inspector to check real-time data. In this mode, you can see your network’s live parameters in several ways:
- In the table, pay attention to the “Graph” column — this shows your signal strength (RSSI, dBm), which helps you understand how stable your connection is.
- −30 dBm to −50 dBm — Excellent: very strong signal, ideal for any activity including video conferencing and streaming.
- −51 dBm to −65 dBm — Good: stable connection, suitable for most online tasks.
- −66 dBm to −75 dBm — Fair: may work for browsing or messaging, but expect slowdowns.
- −76 dBm to −90 dBm — Poor: connection is weak and unreliable, likely to drop frequently.
Here’s how to interpret the signal levels:
The closer the value is to 0 (in negative dBm), the better your signal.
- On the Signal Strength graph, you can track how the signal fluctuates over time — a steady line means a stable connection, while frequent drops indicate weak spots or interference.
- The Channel graphs display how crowded each channel is. Here you can see if your network overlaps with neighbors and whether switching to another channel could reduce interference.
By combining these views, Inspector mode gives you a coplete picture of your WiFi quality in real time, making it easy to spot problems and optimize your setup.
In Survey mode, you can go further and evaluate your Wi-Fi coverage visually. NetSpot builds detailed Wi-Fi heatmaps that show where your signal is strong, weak, or lost completely. This makes it easy to spot dead zones, areas with noise, or places where interference from neighbors affects performance.
If your signal-to-noise ratio is poor, there are a few things you can do to improve it. You can switch to a different WiFi channel to minimize interference caused by other WiFi networks in your area.
If your router supports it, try moving from the 2.4 GHz band to 5 GHz for faster speeds, or even to 6 GHz (Wi-Fi 6E/7) for the cleanest spectrum and highest throughput. Just keep in mind: 2.4 GHz covers longer distances but is slower, 5 GHz is faster but has shorter range, and 6 GHz works best in open spaces and shorter distances.
In Planning mode, you can take it one step ahead. Here NetSpot lets you create a virtual model of your home or office, test different router or access point placements, and even simulate various hardware options.
With predictive heatmaps, you can see in advance how changes will affect coverage and performance — helping you choose the right equipment and the best spot for it before you spend money.

Wi-Fi Setup — FAQs
How do I set up a strong and secure Wi-Fi network at home?
The first step is to set your router in a central location, enabling WPA3 encryption, using a strong admin password, and updating firmware regularly. Use a Wi-Fi analyzer like NetSpot to find weak spots and interference.
What’s the difference between Wi-Fi 5, Wi-Fi 6, and Wi-Fi 6E?
Wi-Fi 5 (802.11ac) is older and supports 5 GHz; Wi-Fi 6 adds faster speeds and efficiency; Wi-Fi 6E introduces 6 GHz for cleaner, high-speed connections. Wi-Fi 7 is the newest, with improved performance and lower latency.
Should I upgrade to a mesh Wi-Fi system or use a Wi-Fi extender?
Mesh systems are better for seamless whole-home coverage and multiple floors. Wi-Fi extenders are cheaper but often reduce speed and don’t support roaming between zones.
What’s the best channel for my Wi-Fi router?
For 2.4 GHz, use channels 1, 6, or 11 to avoid overlap. For 5 GHz and 6 GHz, use NetSpot to scan your area and pick the least congested channel.
