Has your internet speed dropped, leaving you frustrated with a slow modem?
If web pages load slowly or your connection keeps dropping while streaming videos, it’s time to optimize your modem.
In this article, we’ll guide you step by step on how to boost your modem’s internet speed and, with a few simple yet professional tricks, enjoy a faster and more stable Wi‑Fi experience.
Choose the Right Modem Location (The Secret to Stronger Wi‑Fi Signals)
The placement of your modem plays a crucial role in both the speed and strength of your Wi‑Fi signal.
Even the most powerful modems cannot deliver their true speed and performance if placed in an unsuitable location.
✅ Golden Tips for Choosing the Best Modem Location:
Place your modem in the center of your home or office to ensure better signal coverage throughout the area.
Do not place your modem near metal objects, TVs, refrigerators, or microwaves, as these can cause interference and reduce your internet speed.
Place your modem on a higher surface, such as a shelf or table, so that Wi‑Fi signals can spread more effectively throughout the space.
By following these simple tips, you can improve your modem’s signal strength and enjoy a faster, more stable internet experience.
2. Use the appropriate frequency band (2.4GHz or 5GHz).
One of the easiest ways to boost your modem’s Wi-Fi speed is to choose the right frequency band. Most modern modems are Dual Band and offer two different bands:
2.4GHz band: Offers wider coverage and longer range, but its speed is lower.
5GHz band: Offers much higher speeds, but its range is limited and it has difficulty passing through obstacles like walls.
Denatech DS135 and TD42 modems feature Dual Band support, allowing use of both 2.4GHz and 5GHz bands.
By choosing the frequency band wisely, you can noticeably improve your modem’s internet speed and stability.
3. Set a strong password for your Wi-Fi (to enhance your modem’s security and speed).
One of the main reasons for slow Wi-Fi speeds is unauthorized use of your network by others.
If your Wi-Fi is unprotected or secured with a weak password, strangers can easily connect to it and slow down your internet speed.
🛡️ Security Recommendations for Modem Encryption:
Set your modem’s encryption type to WPA2-PSK or, on newer models, to WPA3; these two options are the most secure.
Choose a strong, mixed password that includes numbers, uppercase and lowercase letters, and special characters (!@#).
Avoid simple passwords like 12345678 or using your personal name.
By choosing a secure and complex Wi-Fi password, you not only increase your network’s security but also prevent unnecessary internet usage and slow modem performance.
4. Update your modem’s firmware to improve speed and security.
Many users don’t realize that updating the modem’s firmware can have a significant impact on Wi-Fi speed, stability, and security.
Companies such as TP-Link, D-Link, Huawei, and ZTE — as well as all Denatek modems — regularly release new firmware versions to improve device performance and fix bugs.
🔧 How to Update Your Modem’s Firmware:
Log in to your modem’s settings panel (usually by typing 192.168.1.1 in your browser).
Go to the Firmware Update section or navigate to System Tools → Upgrade.
Download the latest firmware version from the modem brand’s official website and upload the file.
Wait for the update process to complete, and the modem will automatically restart.
⚠️ Important Note:
Do not turn off the modem during the update process, as it may damage the device.
With this simple step, you can boost your modem’s internet speed while also enhancing its security against intrusions and cyberattacks.
5. Limit the number of devices connected to your modem (for better bandwidth management).
One of the main reasons for slow Wi-Fi speeds is having too many devices connected to the modem.
The more devices such as smartphones, laptops, smart TVs, or gaming consoles are connected to your modem, the more the bandwidth is divided among them, reducing the speed for each device.
💡 Practical Tip:
Through your modem’s settings (Device List or Connected Devices section), you can view all connected devices.
If you notice any unknown devices or devices that don’t need to be connected, you can block or disconnect them to increase internet speed for the remaining devices.
✅ By managing the number of connected devices, you can reduce internet usage and improve your modem’s performance.
6. Change your modem’s Wi-Fi channel (to reduce interference and increase speed).
Have you ever noticed a sudden drop in your Wi-Fi speed?
One hidden reason for slow wireless internet is Wi-Fi channel interference in crowded environments.
When multiple modems nearby are active on the same channel, their signals interfere with each other, reducing your actual internet speed.
📶 Simple Solution:
Log in to your modem’s settings panel (common address: 192.168.1.1)
Go to Wireless Settings → Channel.
Select one of the less crowded channels, such as 1, 6, or 11, and save the settings.
💡 You can use apps like WiFi Analyzer (on Android) or NetSpot (on Windows and macOS) to identify the busiest and least crowded channels.
By changing your Wi-Fi channel, signal interference is reduced, resulting in a noticeable improvement in your modem’s internet speed and stability.
7. Use a LAN cable instead of Wi-Fi (for higher speed and stability).
If you want the highest internet speed, nothing beats a wired connection!
Using a LAN (Ethernet) cable creates a direct, interference-free connection to your modem, resulting in significantly higher internet speed and stability compared to Wi-Fi.
🎮 Benefits of Using a LAN Cable:
Faster, lag-free connection, ideal for online gaming.
Smooth, uninterrupted playback for 4K videos and live streaming.
Prevents signal drops and interference commonly experienced with Wi-Fi.
📌 If your device (like a laptop or PC) has a network port, simply connect it to the modem with a LAN cable to enjoy the best internet connection quality.
8. Restart your modem every few days (to restore internet speed).
Modems, like any other electronic device, can experience reduced performance after being on for a long time. Cache memory and software glitches can cause slower internet speeds and unstable Wi-Fi connections.
📌 Simple and Effective Solution:
Turn your modem off and on (restart) every few days.
This helps to:
Clear the modem’s cache memory.
Resolve temporary software issues.
Restore the internet speed to its normal level.
💡 This simple method, without the need to change settings or buy new equipment, is one of the quickest ways to boost your modem’s speed and internet stability.
9. Use a Wi-Fi extender or Mesh system (for full internet coverage at home).
If your home or workplace is large, or if there are thick walls between the modem and devices, the Wi-Fi signal may be weak in some areas or frequently drop.
💡 Effective Solutions to Improve Internet Coverage:
Wi-Fi Extender:
A device that receives the modem’s signal and rebroadcasts it, ensuring adequate coverage in the farther areas of your home.
Mesh Wi-Fi Systems:
A network of modems or nodes that work seamlessly together to provide uniform Wi-Fi coverage throughout your home.
✅ By using these devices, you can noticeably improve internet speed and stability throughout your home, eliminating weak signals and Wi-Fi drops.
10. Check your internet service (to ensure the issue isn’t with your modem).
Sometimes, slow internet isn’t caused by your modem but by your internet service provider (ISP).
Before making any changes or spending extra money, it’s best to test your actual internet speed.
✅ How to Check:
Go to the website Speedtest.net.
Measure your download and upload speeds.
Compare it with the speed of your purchased plan.
📌 If your internet speed is much lower than expected:
Contact your ISP’s support and report the issue.
Sometimes, replacing the modem or checking the wiring by your service provider is also necessary.
By following these 10 simple and professional tips, you can significantly improve your modem’s internet speed and stability, enjoying a smoother, uninterrupted Wi-Fi experience.
