Why is My Internet So Slow? It Maybe Because of Network Cables!

With the development of communication technology and the Internet, operators began to offer home broadband services of 200 Mbps, 500 Mbps and 1Gbps to ordinary consumers to meet the bandwidth needs of different users. However, when some users tested the network speed of computers, mobile phones and tablets connected through routers after the high-speed broadband service was opened, they found that the actual network speed was far less than that advertised by the broadband service. Contact operator after sale to carry out door-to-door detection, the result modem network speed is normal.

Every time we complain about the home internet speed is too slow, because of the bad router. However, should our router be the main reason?

Maybe not!

Today, I am going to tell you the other reason, the wrong network cable.

What causes the speed drop? Is it really your router’s problem? But the router at home is newly bought, and the cable, wireless is also dry Megabyte level, how the network speed or do not go? Seems to have nothing to do with the speed of the network cable, whether to be ignored by everyone? The router connects to the modem and the router connects to the computer using an Internet cable. If not used properly, the cable can also cause the speed of the network to slow down!

The composition of the cable:

The composition of the cable

The main purpose of the type classification of network cables. You also can find the comparison: cat5 vs cat5e vs cat6 vs cat7.

Category Main Application Max Transmission Rate
Category 1 Cable Voice transmission
Category 2 Cable Voice and data transmission 4Mbps
Category 3 Cable Token network 10Mbps
Category 4 Cable 10/100 base-T network 16Mbps
Category 5 Cable Ethernet network 100Mbps
Category 5e Cable Ethernet network 1Gbps
Category 6 Cable Gigabit Ethernet Network 1Gbps
Category 6a Cable Gigabit Ethernet Network 10Gbps
Category 7 Cable 10 Gigabit Ethernet 10Gbps

At present, we most commonly use cat5, cat5e, cat6 and cat7. Among them, the cat5 cables have been replaced by the cat5e cables. The cat7 cables cost relatively high and are rarely used in actual families. So, even if installed gigabit bandwidth, but if the use of cat5 cable, network speed is not up is normal.

How to distinguish cable types?

The easiest way to distinguish cable types is to look at the identification parameters on the cable sheath. Cat.6 Generally, there is a string of code on the sheath of the network cable, indicating the brand, model, wire specification, certification standard, wire core specification, wire type, shielding method, meter number and other information of the network cable.

How to distinguish cable types

The two parameters we need to focus on are the type of network cable and masking mode.

The code for common cable types and masking methods is shown below.

Network Cable Types Shielded Methods
Category Code Code Description
Category 5 CAT5 UTP Unshielded Twisted Pair
Category 5e CAT5e FTP Foil Twisted Pair
Category 6 CAT6 STP Shielded Twisted Pair
Category 6a CAT6a SFTP Shielded Foil Twisted Pair
Category 7 CAT7 ASTP Armour Shielded Twisted Pair
From top to bottom, the higher the transmission rate. From top to bottom, the stronger the anti-interference ability.

How to choose the network cable?

(1) Select according to the speed of the Internet:

100/200/500Mbps broadband: Super class 5 or higher

1000Mbps or higher broadband: super class 6 or higher

(2) Final selection according to usage scenario:

①Short distance connection and non-wall wire-routing scenario:

it is recommended to choose UTP type non-shielded network cable, save money!

②Wall wiring (new house decoration or old house reconstruction) Scene:

The distance < 1.5m from the power supply line: SFTP

The distance ≥ 1.5m from the power supply line: FTP/STP

One more point, when making your own cable please pay attention to: do not mix different types of crystal head! Once you have selected the cable type, you need to use the same type of crystal head to make the cable. Otherwise, the network speed is still possible to slow down.
