In the Internet age, the most complaints received by network operators are: My internet speed is too slow!
Research shows that most Wi-Fi users actually only use half the WiFi speed of a wireless router. There are usually several reasons for this:
1. Signal congestion is the biggest culprit of weak Wi-Fi signals
When you connect to Wi-Fi, you use radio waves. Like radio stations, radio channels in the air are also limited, so the number of wireless routers around you, such as your building and street, is the key to the problem. The more routers there are, the more serious the radio waves in the air are congested. This is similar to the reason that traffic jams are.
It is irritating that even if the signal is congested even when the signal is displayed on the mobile phone, it is not only the router, but also the radio waves emitted from mobile phones, cordless phones, microwave ovens, Bluetooth devices, and even cordless baby monitors. Will weaken Wi-Fi signal strength.
Consider that when you use Wi-Fi, you often need to cross 1 or 2 walls to connect routers, so the competition for routers in your home/office is very fierce, and routers often feel very aggrieved - "I'm easy What am I!"
2. Wi-Fi devices cannot send and receive signals at the same time
Wi-Fi is the need to convert between sending and receiving data. There is a technical term called "half-duplex system."
Full-duplex systems, such as wired LANs, can send and receive data at the same time.
For example, a half-duplex system is like a single lane, and two-way traffic is available. Everyone has to queue up and use the only lane. A car in one direction takes some cars in another direction. The full-duplex system is like a two-way lane, and you walk away from me and everyone from me does not interfere with each other.
Therefore, compared with other network connections, Wi-Fi delay is a natural phenomenon.
And when there are many people using the same channel, this situation is even worse!
Routers can use a number of different channels to generate wireless signals, and users often have routers "automatically select channels" when they set up routers. This often results in the vast majority of home Wi-Fi using the same channel at a crowded 2.4 GHz frequency, which makes congestion even worse.
In addition, if you live in a densely populated area, "Automatically Select Channels" will make the router constantly try to find the best channel and try again, which will also affect your Wi-Fi signal.
3. Wi-Fi is generally not as fast as a wired LAN. We can do nothing about it, so if you want fast speed, then plug in the cable.
At this stage, Wi-Fi is a convenient and complementary solution for wired LANs, and it is neither a nor a substitute for Wi-Fi. The wired network will always exist in the backbone network, and the wireless access to the edge is the major trend of the network development. For surfers pursuing speed, plugging in the Internet is always a better choice!
4. Still slow? Are you watching the IPTV HD movie while playing the game while still playing BT, plus several mobile phones while scanning the WeChat friends? This usage will definitely affect the Wi-Fi speed
The above applications are large users of bandwidth, and they tend to run in the background. You may not realize that these large users are fighting for your bandwidth to grab bandwidth. Turn off some applications and you will notice that there are network speeds. Improved.
5. The location of the router installation is also very important
Wireless routers send omnidirectional signals. The closer a router is to an obstruction, such as a thick brick wall, the more easily the signal is suppressed. Ideally, the router should be placed in the center of the house suspended below the ceiling, which will produce the best results, but the reality often does not allow us to do so. So the closer the router is placed to the ideal position, the better.
6. Don't forget that Wi-Fi devices also have a good connection
If you find that you are also surfing the Internet in your home and your friend's 6S is faster than your 4S, don't be surprised. The more new equipment, the better its performance, the faster the processing speed, and the faster the Internet speed is not surprising.
So how do you get faster Wi-Fi speed?
– Of course, the first step is to upgrade the router, and upgrading to a dual-band 11AC 5GHz router is definitely stronger than the old 2.4GHz. (One thing to be reminded is that although 5GHz Wi-Fi is fast, the current level of technology is slightly inferior to 2.4G in terms of wall wear, and there are many mobile devices that do not support 5GHz at the moment. Of course, as technology advances rapidly, Development is not an issue.)
– Select a less congested channel for the router. (For the complete white, keep the “automatic channel selectionâ€, and saving your election will make things worse.)
– Adjust the installation position of the router. As described above, the closer to the ideal position, the better.
– Use a signal booster to enhance the Wi-Fi signal where the signal is weak. Or use a powerline product to transmit the signal through the powerline to a place where the Wi-Fi signal is weak, and then use this powerline Wi-Fi Extender to generate the Wi-Fi signal.
– Less common situation: If there is transmit power selection on the router, it is obviously better to choose high transmit power than Wi-Fi signal with low transmit power.
At this point, you are ready for wireless surfing!
