Analysis of The Causes of Home Network Quality Problems

The quality of the home network is mainly related to the performance of the home network devices, the connection between the devices, the quality of the wifi signal in the residence, and the use of the user.

1 Performance of equipment

The performance of the equipment that has a big impact on the wifi network speed mainly includes: the bandwidth capacity of the router, the bandwidth capacity of the optical cat, and the stability of the equipment.

1.1 Bandwidth capacity of router

The bandwidth capacity of some routers that have been in use for a long time is poor:

(1) WAN port only supports 100Mbps at the highest.

(2) The wifi only supports 2.4G single frequency; the maximum download rate supported by 2.4G single frequency router is affected by the number of router antennas on the one hand, and the interference of the same frequency in the usage environment on the other hand, and the maximum rate is generally not more than 200Mbps.1.2 Bandwidth capacity of optical cat

The bandwidth capacity of the old optical cat is similar to that of the router:

(1) The maximum LAN port only supports 100Mbps.

(2) The wifi of optical cat only supports 2.4G single frequency; when using the optical cat as AP, 2.4G single frequency optical cat will form a constraint on the wifi network speed.

1.2 Stability of equipment

Some models of optical cats and set-top boxes have poor stability, which can easily lead to network failure. Routers are usually purchased by users themselves, and some cheaper routers have poor stability. Old Dingtou had bought a 99 yuan router, which often dropped the line, and the problem was solved by replacing it with a 200 yuan router.

2 Connection between devices

2.1 Router and optical cat connection

The main reasons for the connection between the router and the optical cat include:

(1) The set-top box and the router share a common network cable. Many users' optical cats are installed in the home information box, and the router is placed next to the TV set. However, the location of the home information box to the TV set is usually only a network cable, put the installation, installation and maintenance personnel will often be divided into two groups of four pairs of cable, each group of two pairs of wires, respectively, connected to the router and set-top box. Although this is available, the two pairs of wires only support a maximum transmission rate of 100Mbps.

(2) Misconnecting the LAN port of a Gigabit fiber optic cat. The LAN port of the Gigabit fiber optic cat usually contains one Gigabit port and one to two 100Mbps ports. The identification of the Gigabit port and the Hundred Megabit port is not obvious, which causes users to connect incorrectly.

(3) Inferior network cable. Some home wiring uses poor-quality network cables, making it difficult for the transmission rate between the optical cat and the router to exceed 100 Mbps.

3 User's use

The reasons related to the user's use mainly include: the use of the wifi 5G band, the long continuous use of the device, and the excessive number of terminals accessed by the AP.

3.1 Unused wifi 5G band

Since the wifi connection of some devices must use the 2.4G band, the user's dual-band router or dual-band optical cat is often set to two different wifi subnets. Users do not pay attention to the difference between the two wifi subnets and do not connect to the wifi subnet of the 5G band, thus leading to limited network speed.

3.2 Long continuous use of devices

We all have the experience of using cell phones and computers that if they are left on for a long period of time (e.g., more than 10 days), they will run slower, and then restart them. The same goes for routers, optical cats and set-top boxes in the home network. If they are used continuously for a long time, the operation of the equipment will become slower and slower, resulting in Internet lag for users.

3.3 AP access to too many terminals

The ability of AP to access wifi terminals is related to the performance of the AP, when the AP is an optical cat or some low-end router, the wifi terminals that can be accessed at the same time are usually about 10, and the number of wifi terminals that can be accessed at the same time by high-end routers is usually more than 20. When the number of terminals accessed by the AP is not matched to the access capacity, it will also deteriorate the user's Internet experience.
