Here’s a practical guide to solving common Wi-Fi problems, from simple tweaks to advanced fixes. Let’s start with the basics and work our way up.
Setting up network security is a simple yet crucial step for every Wi-Fi user. An unsecured network can slow down your internet and even put your personal data at risk.
Securing your Wi-Fi
Securing your Wi-Fi means creating a strong password, using the latest encryption, and regularly checking connected devices.
Tips:
- Create a strong password: Use at least 12 characters with a mix of letters, numbers, and special symbols to make it harder to crack.
- Use modern encryption: Set your router to WPA2 or WPA3 for the best protection against unauthorized access.
- Set up a guest network: Create a separate network for visitors to keep your main devices and data safe.
2. Restart Your Router
Restarting your router is a quick and effective way to restore network stability. Over time, routers can slow down due to errors or overheating. A reboot clears the device’s memory, fixes temporary glitches, and helps it perform at its best again.

3. Update Firmware and Drivers to Improve Wi-Fi Performance
If restarting your router doesn’t improve performance, the next step is updating its firmware. Outdated firmware can have bugs or vulnerabilities that impact speed and connection stability.
Updates not only fix issues and close security gaps but also optimize performance and may add new features like parental controls, guest networks, and advanced QoS settings to better manage traffic and enhance usability.
Updating Router Firmware
Updating your router’s firmware may vary depending on the manufacturer. First, find your router's model and version, usually printed on a label on the device or in the documentation. For a stable connection during the update, use an Ethernet cable.
Then enter the router's IP address 192.168.X.X in a web browser, where X should be replaced by numbers that may depend on the specific model (usually 192.168.0.1 or 192.168.1.1), log in to the admin panel using the administrator login and password specified in the instructions or on the device. In the firmware update section, which may be called "Update", "Firmware Update" or "System Upgrade", check if a new version is available.

Tips:
- Check compatibility: Always ensure the firmware and drivers you download match your device model.
- Backup your settings: Before updating your router’s firmware, save your current settings to avoid having to reconfigure your network from scratch.
- Don’t power off during updates: Interrupting the update can corrupt the firmware and render your device unusable.
4. Selecting the Best Wi-Fi Channel for Maximum Signal Quality
In densely populated areas with many neighboring Wi-Fi networks, channel congestion is one of the main culprits behind slow speeds and unstable connections.
Example of Wi-Fi network congestion in the 2.4 GHz band
Most users stick to their router’s default settings, leaving their networks operating on the same channels, which leads to heavy interference. Optimizing your Wi-Fi channel can significantly reduce this interference and improve signal quality. Switching to a less crowded channel or band minimizes disruptions and boosts connection stability.
How to choose the best Wi-Fi channel
- Open Inspector Mode in NetSpot to identify less congested channels.
- Select the best channel.
-
- For the 2.4 GHz band, non-overlapping channels like 1, 6, or 11 are preferable for minimizing interference, but it’s important to choose a channel that is the least congested. If this isn’t possible, choose a fully overlapping channel since devices can “negotiate” and reduce conflicts. Access your router’s settings via the web interface (usually at 192.168.0.1 or 192.168.1.1), locate the wireless settings section, select the less congested channel, and save the changes.
-
- If your router supports the 5 GHz or 6 GHz bands, switch to one of them. These bands offer higher speeds, experience less congestion, and are less prone to interference from household devices. However, keep in mind that 5 GHz and 6 GHz signals don’t penetrate walls as well and may not be compatible with older devices.
Tips:
- Regularly check channel congestion, as the situation can change over time.
- Combine the 2.4 GHz, 5 GHz, and 6 GHz bands: use 5 GHz or 6 GHz for high-speed devices close to the router, and 2.4 GHz for devices farther away.
5. Optimizing Router Placement for Best Wi-Fi Coverage
If the previous steps haven’t made a big difference, try improving your Wi-Fi coverage by moving your router. People often place their routers where it’s most convenient — on the floor, in a corner, or near other devices — but this can seriously affect network performance.
Various obstacles, such as thick walls (especially concrete or metal-reinforced ones), metal furniture, electronic devices (like microwaves and cordless phones), and even aquariums, can weaken the signal and create "dead zones."
How to use NetSpot to identify weak zones and find the best spot for your router
- Create a Wi-Fi heatmap
-
- Launch Survey Mode in NetSpot: Open the app and select the “Survey” mode.

- Calibrate the plan: Use the “Line” or “Area” tools to adjust the dimensions accurately.
-
- Scan your space: Choose active scanning mode for more detailed results. Walk through all the areas you want to scan, allowing NetSpot to collect data on signal strength and speed.
-
- Analyze the heatmap: Once the scan is complete, NetSpot will generate a heatmap showing areas with strong and weak signals. This will help you pinpoint problem zones and decide where to improve coverage.
- Move your router
- Based on the heatmap results, relocate your router or access point to a more optimal spot.
- Avoid placing it near thick walls, large metal objects, or electronic appliances like microwaves and cordless phones.
- Position the router in an open area, centrally located in the room, and elevated, such as on a shelf or mounted on a wall.
- Check the changes
- After moving the router, run another analysis in NetSpot to confirm that Wi-Fi coverage has improved and weak zones have been reduced.
Tips:
- Adjust the router’s antennas: Change the angles and orientation of the antennas to optimize Wi-Fi coverage in your space.
- Ensure proper ventilation: Make sure the router’s vents are clear of obstructions to avoid overheating, which can degrade performance.
- Expand your network: If coverage issues persist, use Wi-Fi extenders or a Mesh system to eliminate dead zones and ensure seamless connectivity.
