Why Modify Your Router?

Modifying your router can help in many ways, however the main goal of modifying a router is to achieve increased upload/download throughput.

Below we will touch upon how a modified router can help you. Whatever the environment, Router-Mods is here to help.


Signal is one of the most important factors that determines the stability and performance of 3G/4G/5G connections. Better signal results in higher throughput and connection stability.

Routers are reliant on their internal antennas for their signal. however routers are normally place inside at low level behind solid objects such as walls doors and windows and neighbouring buildings, these objects play a big part of blocking/reducing the signals the router receives.

Using a modified router allows you to use and install external antennas to overcome these restrictions allowing you to achieve the best signal for your environment.

Some routers do have factory external antennas inputs, but we will talk about this below.

4G Router Factory Antenna Ports

Many routers come with factory antenna ports, allowing you to attached a 2×2 external antenna. Many routers also specify they have 4×4 MIMO technology (4 Internal antennas). This is great right? Wrong!

Although its great that some manufacturers offer external antennas, what many many don’t realise is that by using these external antenna connection you actually downgrade the routers capabilities, performance and throughput. let’s explain a little. . . . .

While the router maybe using 4 internal antennas but receiving weak signal, the router will be utilising 4×4 MIMO and CA (Carrier Aggregation) technology performance increases. When you choose to use to use the external antenna ports, although you might be achieving better signal with external antenna the routers capabilities are actually reduced to 2×2 MIMO and limited CA capabilities. The internal antennas are disabled.

This is where the modification comes in, as the modification exposes all the internal antenna connections. This allows you to take full advantage of the routers full potential while using external antennas to achieve the best signal and throughput possible.

5G Router Factory Antenna Ports

Take into consideration the “4G Factory Antenna Outputs” section above as this still applies to 5G routers too. But things are a little different for 5G routers and their factory antenna ports.

While 4G routers have reduce capabilities when using factory antenna ports. Many 5G router antenna ports are for 5G only, they do not work for 4G. Many people buy antennas with hopes of using these antenna ports and see not difference in signal or throughput.

5G NSA uses the backbone of the 4G infrastructure, this means that 5G can not work without 4G. Both 5G and 4G are then used in parallel to produce the overall throughput. 4G connection must also connect to a 4G ENDC uplink mast (not all masts have this). What does this mean?

Well as 5G is reliant on 4G, this means although you may have attached a 5G antenna to the factory outputs, the router is still reliant on the internal 4G antennas for the connection and initiation of 5G. If your router is receiving low 4G signal or not connecting to the 4G ENDC uplink mast, no 5G instruction will be sent to the router to initiate the 5G connection.

Low 4G and 5G signal is the cause of unstable, unusable 5G connections and routers dropping their 5G connection.

Router modification helps rectify these issues buy allowing you to attach multiple external antennas to both 4G and 5G ports granting you access to a stable 5G connection. In many situations even achieving 5G when your technically “outside of network coverage area”
