What Should You Consider When Choosing a Modem/Router?

The quality of your internet experience depends not only on your service provider but also on the devices you use. In wireless technologies like VDSL, selecting the right router (often referred to as a “modem” by users) is critically important.

Choosing the wrong device may lead to problems such as low speed, signal dropouts, or weak coverage. Below are the key technical points to consider when buying a modem/router:

1. Home Size and Number of Antennas

• Small homes (1+1 or 2+1, 60–90 m²):
  Routers with 2 antennas are generally sufficient.
• Medium homes (3+1, 100–150 m²):
  Routers with 3 or more antennas are recommended. More antennas mean wider signal distribution.
• Large homes or multi-story buildings (duplexes, villas):
  In addition to high-gain antennas, using powerline adapters or mesh Wi-Fi systems is highly recommended.

Note: In addition to the number of antennas, the dBi value is also important. Higher dBi means longer range.

2. Why Is Wi-Fi 6 (802.11ax) Support Important?

Wi-Fi 6 is the latest generation wireless standard and offers major advantages in households with multiple connected devices or demanding speed requirements:

• Higher speed and wider coverage
• Maintains performance in crowded networks
• Lower latency in online gaming, 4K streaming, and video calls
• Lower power consumption for mobile devices

Recommendation: If you're buying a new device, routers with Wi-Fi 6 support are the most future-proof investment.

3. Differences Between 2.4 GHz and 5 GHz Frequencies

2.4 GHz Band:

• Offers wider coverage
• Provides moderate speed
• More prone to interference from other devices
• Stronger wall penetration
• Ideal for distant rooms and wider areas

5 GHz Band:

• Narrower coverage range
• Delivers higher speeds
• Less interference
• Weaker wall penetration
• Best for high-speed use in the same room

Summary:

• Use 2.4 GHz for longer distances and broader coverage
• Use 5 GHz for high-speed activities like gaming, streaming, and large downloads
• Dual-band routers provide both frequencies and allow your device to connect to the most suitable one automatically

4. Use Powerline Adapters Instead of Repeaters

Many users turn to Wi-Fi repeaters to extend their signal, but these often weaken performance, increase latency, and cause conflicts.

At FixNet, we recommend using powerline adapter systems instead.

How does powerline technology work?

1. One powerline adapter is connected via Ethernet to the router in the main room and plugged into a power outlet.
2. A second adapter is plugged into a power outlet in another room on the same electrical circuit.
3. The second adapter provides a new internet access point in that room.
4. This allows you to extend your network without running cables, delivering a strong and stable signal.

Benefit:
In homes with thick walls, large square footage, or multiple floors, powerline adapters offer both practical and reliable coverage.

5. Other Key Features to Look For

• Gigabit Ethernet Ports: Essential for high-speed wired connections
• IPv6 and VPN Support: Necessary for modern and secure networking
• Mobile App Management: Some routers allow easy setup and monitoring via smartphone apps
• Separate Router + Access Point Use: Ideal for advanced users who want full control and custom setups
