I often encounter WiFi but it is very slow. I can only do it urgently. Is it because many people have encountered such a situation? Do you really want to know what causes WiFi to slow down? Here Xiaobian will analyze for you from six reasons.
I often encounter WiFi but it is very slow, I can only be anxious. The general explanation is related to the network bandwidth and the number of users. I want to know what other reasons can make WiFi slow down?
The slow speed of the network has almost become the topic of the highest frequency of complaints received by each broadband operator. Studies have shown that most consumers currently use WiFi speeds of only about 50% of their router bandwidth cap.
The reason why WiFi speed does not meet everyone's expectations is related to these six factors.
1. WiFi signal congestion
When a user accesses the network through WiFi, it is actually like a radio station. It uses a fixed-frequency wireless band. So how many similar signal transmission and receiving devices around the user's area will make a difference to the WiFi experience. influences.
New Zealand engineer Steve Biddle, who has researched wireless hotspots, wrote in an article last week: "If you live in a central apartment building in the city center, there are several in this apartment building. With hundreds of wireless networks in existence, this is almost the worst WiFi usage environment."
Even if the WiFi signal bar on your mobile phone is full, the actual WiFi signal may be very slow, and the mobile phone, cordless phone, microwave Shanghai, Bluetooth device or even wireless baby monitoring device may affect the signal quality of WiFi.
2. The device cannot send and receive data at the same time.
Since the WiFi signal cannot transmit and receive data at the same time, this makes the network access method generate more data delay than other methods. Moreover, many people using the same WiFi channel at the same time will greatly affect the signal strength of WiFi.
In fact, your router can usually use hundreds of WiFi channels, but most people only adjust the router channel selection options to "automatic" mode, so most people are using the 2.4GHz frequency channel that is now very crowded. . In addition, if you are in an area with abundant network signals, your router will continue to find the best network channel, which will also cause network delay, and this is not a problem that broadband operators can solve.
3. Natural defects
No matter how much the WiFi technology will improve in the future, the wireless connection method will be hard to exceed the existing wired Internet access mode.
WiFi does not completely replace wired internet connections, it is just a more convenient networking solution.
4. Background work
If the WiFi speed does not improve after all of the above factors have been removed, check to see if your software is automatically syncing data and photos. In fact, applications such as Steam, Netflix and BitTorrent, the world's largest integrated digital distribution platforms, will transfer files in the background, which will greatly affect the user's WiFi speed. Moreover, since most of these applications work silently in the background, many users simply can't think of them.
5. Router location
The placement of the wireless router has a very large impact on signal strength. For example, if you place the router on the edge of a cement wall, its signal strength will be greatly reduced. If possible, the best place for the router to place is naturally on the ceiling in the middle of the room (of course, many consumers do not have such conditions).
6. Connect device differences
If your iPhone 3G WiFi connection speed is not as fast as the iPhone6, don't be surprised, because the connection speed of WiFi is also closely related to the information processing speed of the connected device.
Four suggestions:
1. Upgrade your router device to a dual-band router that can support both 2.4GHz and 5GHz frequencies. However, it should be pointed out that the 5 GHz frequency signal has a wall penetration capability of less than 2.4 GHz, and many older devices do not support this WiFi frequency.
2. Use the channel viewer to find the WiFi channel usage in your area, and then select a more smooth channel to use.
3. If you have an idle wireless router on hand, consider using wireless signal relay or amplification to enhance the WiFi signal strength in the room.
4. If your router has different power usage options, such as high power and low power, usually the low power usage scheme will have better WiFi signal strength.
