How to replace WiFi antenna on wireless router

Most wireless routers and access points contain WiFi antennas that broadcast equally well in all directions. These antennas are omnidirectional, making it easy to set up and set up the router.

Improve router performance

Sometimes, it is better to replace the router's built-in antenna with another one. A omnidirectional antenna can have difficulty reaching far distances, because its signal power must expand in all directions. This can lead to a "dead spot" in the home or business where the signal cannot be reached.

To improve the performance of the router with the new antenna, you need:

1. Replace the existing omnidirectional antenna with a more powerful omnidirectional antenna.
2. Replace existing omnidirectional antennas with directional antennas that have a high gain.
3. Add an omnidirectional or external antenna to the router.

Replace an antenna

Please check the router manufacturer's website. Advanced replacement antennas for your specific router model can be sold here. Even if the manufacturer does not provide replacement antennas, a lot of common antennas are available on the web.

Remember to determine the router network standard before you buy the antenna. It could be wireless N or AC technology, labeled with 802.11n or 802.11ac or other specifications, and you have to buy compatible antennas.

Upgrading the antenna on the router does not require any tools. Just turn on the old antenna and remove the screw.

If the antennas of the routers are not removable, they are probably not replaceable.

Add an external antenna

Some router manufacturers sell omnidirectional and external antennas that are significantly stronger than the router's built-in antennas. A stronger omnidirectional antenna is more likely to reach remote locations within the company or home.

Because WiFi connections are sensitive to distance, stronger connections often result in increased network performance. Many routers offer an external antenna jack that allows for a simple connection to a new antenna, but you should consult the router's product documentation for details before ordering a new antenna.

Directional antennas have a high gain

Larger WiFi range can be achieved with high gain directional antennas, which increases reception in a specific direction. By focusing the signal, the high-gain antenna allows the signal to be better controlled and literally targets the area of ​​the home where the wireless devices are located.

When a stronger signal is not necessarily better

An overly strong wireless antenna can create network security issues. The use of strong omnidirectional antennas can result in WiFi signal spreading to nearby areas where radio signals may be blocked.
