From a technical point of view, a router is a mini computer, which also has a processor, memory and hard disk. Of course, the hard disk of the router is mostly flash memory. If the computer performance is too low, it will crash at work. Similarly, the router's hardware performance is too poor, and it will crash when working.
Broadband has been speeding up in the last year or two, and the performance requirements for routers are definitely higher. Five years ago, they all used 10M broadband, and any router can be used. After all, the maximum data throughput of 10M broadband does not exceed 2M per second. At present, the data throughput of 200 megabits broadband starts at least 20 meters. If the router memory is too small or the processor is too backward, it is easy to crash.
So the easiest way to solve this problem is to replace a router with higher performance. At present, Gigabit routers have become the mainstream, so it is enough to replace a Gigabit wireless router.
When buying a wireless router, try to buy products with larger memory capacity. Of course, the software of the router is also important. To put it bluntly, the software of the router is equivalent to the operating system of the computer. If the system is poor, it will crash for a long time.
At present, the price of entry-level Gigabit routers on the market is around 200 yuan. Wireless routers commonly used by home users include 360 router V4, Glory router X2 and Huawei router WS5200. If you have sufficient funds and high requirements for network speed, you can buy Netgear R6400 or ASUS RT-AC68U, and the prices of these two products are around 700 yuan.
To explain the problem of the topic, we need to start with the composition of the router. A router consists of hardware and software. Like computers and mobile phones, poorly optimized systems run slowly for a long time. Only restart can solve the problem, and so can the router.
A very important criterion for judging a router is its stability. It can work normally and stably without turning it off for 24 hours for a long time, and there will be no problems such as dropped calls and decreased network performance. This has a lot to do with the design level and technology accumulation of manufacturers. While the hardware meets the requirements, it is more important that the firmware technology can monitor the working state of the router in real time and optimize the memory and cache in time without affecting the normal work of the router. In terms of router firmware, ASUS official Merlin firmware is very stable and has won unanimous praise. This is not the cover.
The wireless routers of Netware and ASUS have a very good reputation, mostly because of the stability of their firmware. At present, most of the firmware of routers are developed on the basis of linux, and the manufacturers have strong research and development capabilities and rich technical experience, so the developed firmware is very stable. If the manufacturer's design and R&D capabilities are weak, it can only use open source router firmware, and it has not been optimized. If it runs for a long time, it will lead to the decline of network performance.
Some time ago, the message "Xiaomi router automatically restarts offline" was exposed, and the functions such as cache cleaning, memory defragmentation, CPU process optimization, DNA network acceleration, channel optimization, etc. It cannot be executed automatically. Users need to log on to the router and do related operations manually. These applications will stay in the background to monitor the router performance in real time and optimize it regularly.
When choosing a wireless router, we should not only look at the network parameters and hardware parameters of the wireless router, but also look at the brand. Behind the brand is the manufacturer's R&D strength and technology accumulation. Netware and ASUS are the first choice for high-end routers, and Huawei-branded wireless routers are recommended for mid-end routers, such as Huawei's Glory Pro2, which adopts a self-developed Lingxiao quad-core 1.4GHz processor, 256M memory, 128M flash memory and Lingxiao wifi module. Firmware and hardware have good compatibility, and hardware performance and router firmware are relatively stable and reliable.
It is healthier to restart the router regularly. what do you think? Please leave a message in the comments section to discuss.

As mentioned in the title
The wireless router can't surf the Internet normally after a period of use, so it can reconnect to the network after power failure.
analyze the reasons of failure
Before troubleshooting, disconnect the wireless router to troubleshoot the optical fiber cat and optical fiber. Of course, you can call the maintenance personnel to test whether the port and light attenuation of the optical fiber cat are normal. First of all, is it the fault of the wireless router?
If we can rule out the problems of optical fiber cats and optical fibers.
As for the wireless router, reset the wireless router, connect the mobile phone to the wireless router, and log in to the wireless router background.
First, modify the default IP address of the wireless router.
Second, the channel of the wireless router can be modified.
Third, if you use broadband dial-up to connect to the network, then the mobile phone is set with a broadband account and password, and the broadband connection is set to automatic connection. After saving, log in to the wireless router again and check the wireless router. Will the network be disconnected and automatically connected? Is the data exchange normal? Check whether the uploaded data and downloaded data are normal.
Of course, IP address pool can also be set reasonably to prevent IP address conflict.
However, other methods can also be used to troubleshoot the wireless router itself.
It is worth noting whether the network cable between the optical fiber cat and the wireless router should be replaced and eliminated.
There are many reasons why routers can't access the Internet, and the answers of other respondents I just saw are different. Combined with the actual situation of the subject, the author thinks that this is caused by the router crash.
As we know, the router itself is like a small computer, and it also has its own CPU, memory and operating system. When there are too many devices connected to the router, it will exceed its own processing capacity, thus causing network congestion, which can be solved after restarting, that is, shutting down and restarting the router. This is a daily - happened thing. It is suggested that you can set the number of connections or upgrade the equipment.
Why is this happening? Because the model of the router is too old. In the past, most of our broadband was 2M and 4M, and there were very few more than 10M, so router manufacturers did not do so well in memory and CPU in production. Now that broadband is starting at 20M, the old router can't support such a high network speed. Now, if it is a router in public places such as offices, at least a Gigabit router should be used. If there is more money, families can also consider buying one. The market price of an entry-level Gigabit router is probably around 700 yuan.
I wonder how many megabytes of routers are used by readers? Please leave a comment below to let more people see your opinion. If you think what I said makes sense, please like it and follow me!
Let me share my opinion.
The router will be disconnected from the network every once in a while, and it will be fine after restarting. In fact, this is related to the usage habits and the performance of the router itself.
First of all, I personally speculate that the wireless function of the router should be influential. When there is a problem with the wireless function, it will affect the speed at which we use the wireless Internet. Generally, you can see the router's intranet address by pinging the computer. As for how to ping Baidu yourself, there is another situation where the router itself is not working and it is down. If this happens frequently, my personal suggestion is to change it. Routers are also electronic products, and they need rest just like people. If long-term operation is bound to cause problems, is it appropriate to turn it off? For example, I turn off my phone every few nights, so I don't have this situation, so I should give the router a rest properly.
Of course, in addition to the above usage, the performance of the router itself also matters. It's almost impossible to buy a cheap one and use it for a long time. It's the law to get what you earn. At present, Huawei's router is undoubtedly the best in China, but it is expensive.
The above is my analysis, hoping to help the questioner.
First of all, let's learn about routers: routers are composed of hardware and software.
Secondly, there may be two reasons why the router can't go online regularly:
First, the network is overcrowded.
Second, the utilization rate is too high and the hardware capacity is not enough.
1, network congestion problem, a device in the local area network occupies too much bandwidth for some reason, and if there are too many wireless signals around it, it will interfere with each other, resulting in poor network.
2. The equipment capacity is insufficient, and the router itself comes with CPU, memory and operating system. Its task is to forward data frames. When you connect too many devices, you will exceed their processing capacity. Will lead to network congestion, which can be solved after restarting.
Routers can't surf the Internet every once in a while, but they can be used again after power failure. The reasons can be analyzed from the following aspects.
Part 0 1
The circuit boards and components installed in the coquettish and beautiful skin of routers of various manufacturers are the core components of routers. Under the Linux operating system, with the help of CPU and memory, complete the whole data forwarding, security filtering, and choose the best path to release first. Isn't this a small computer? Since it is a computer, its performance is bound to be limited. It's not hard to understand. Everyone can talk about the PC experience and have a deep understanding. So restarting the router after power failure may be caused by the low performance of the router.
the second part
Although the router technology is mature now, and the manufacturers are various, whether it is router manufacturers, old factories or start-ups, Internet companies are among the industries that produce this product. They maintain their own genetic characteristics, endowing routers with various skins and functions, and some even lose the most important characteristics of routers or reduce the best characteristics and functions. This involves quality issues, including the safety of materials and software. The manufacturer specializes in the production of routers, has accumulated rich experience in product selection for many years, constantly improves and upgrades product quality according to user feedback, and has been developed by many industry security experts. However, the latecomers of the router do not have such advantages. The product quality can be imagined, including the cooling system, aging of components, and material deformation over time, which will lead to problems in the sustained, stable and safe operation of the router, and it can only be resumed after power failure.
the third part
Routers work around the clock, and data is constantly exchanged. Over time, a large amount of accumulation can not be released, leading to a crash and the router can not work normally. If the WIFI password setting is simple, it will open the door for "surfing the Internet" users, and it will also affect the routing network. If the router is restarted after power failure, it can release junk files, cache data, reorganize the detection program and restore the normal work of the router. In addition, it is recommended to reset the complicated WIFI password. It is recommended to use WAP2 encryption method with a length greater than 8 bits. Passwords consist of numbers and letters.
part four
The upstream of the router is the ISP, and sometimes the optical fiber signal of the ISP is attenuated, and the failure of the optical cat will also affect the user's access to the Internet. Routers and downstream access network devices can also be replaced for testing. After all, broadband is a closed-loop network composed of many elements, and any one of the members may be the source of the fault. There is no harm in thinking and measuring more.
suggestion
A high-quality router will not break down if it is not restarted for one year. Some routers may have to be restarted once a week to be used smoothly. If the phenomenon mentioned in the topic is restarted every day, it may be that the router hardware has really come to the end of its life. It is recommended to replace the router.
There are many cases where there is a router at home. Sometimes shut down and restart, sometimes plug in the network cable. This is a common practice and sometimes it is really useful. Sometimes the general method doesn't work, it will restore the factory settings and reset the router parameters. If the router can be used normally, it indicates the hardware or software problems of the router. Still can't solve the problem, there may be many reasons.
Due to the increase of terminals, the network may be disconnected; Originally, the terminal was not disconnected from the network, but later, with the terminal, you can check the receiving end, such as the computer end. It may also be influenced by the family environment, such as being close to home appliances. It may be the antenna position of the wireless router, which should be debugged according to the use environment.
Network disconnection may be caused by channel conflict; When using the same channel with multiple neighbors, the network will be disconnected due to unsatisfactory transmission. Network disconnection is caused by channel conflict, so the conflict can be reduced by configuring and managing routers.
Network disconnection may be caused by heat dissipation problems; The router is turned on for a long time, and the poor heat dissipation of the router leads to frequent network disconnection. You can turn off the power for a while and then turn it on. Normal use is also caused by heat dissipation problems. It may be that many users lead to the disconnection of the network; Some people surf the internet at the same time, and using it at the same time will also lead to disconnection. At this time, you can set up a router to prevent others from surfing the internet. The network may be disconnected due to excessive load; If there are too many wireless routers or routers are overloaded, it may lead to network crash or disconnection. The number of wireless routers can be limited, as can the traffic and broadband downloaded by BT.
The performance of the low-end router used is not very good, and there are relatively few problems when choosing the high-end router, such as crash and network disconnection.
I am glad to answer this question for you. I hope my answer will help you. This is my personal opinion and opinion. Please leave a message if you have different opinions. We discuss study together.
1, the network is disconnected every few minutes, sometimes even a few minutes. It will get better after a while?
Answer: It is either your problem or the DNS server's problem. How to detect? Watch carefully. If QQ is online, the web page can't be opened and the gateway is connected, then it is a DNS server problem.
2. I haven't been in touch for a long time. Restart the router, and then it's okay?
Answer: The router is unstable. Strengthen heat dissipation or change to high quality.
3. Can't reconnect after a short network?
Answer: Check whether the link interface and other links are firm.
If this problem always occurs, contact the operator in time to find and solve the problem.
Suggestion:
1. Place the router in a ventilated and open place. Users who often hang up and download can install radiators if possible.
2. Try not to use wireless mouse and keyboard, especially near wireless devices such as set-top boxes. Stay away from the radiation sources of microwave ovens and cordless phones. If possible, you can replace the 5Ghz router to avoid the congested 2.4Ghz band.
3. Check whether the connection between WAN port and LAN port of router is loose, and reconnect to ensure reliable connection.
4. Replace the router.
The above is my answer to this question, written according to my knowledge and experience. Please correct me if there is any immaturity. At the same time, if you like my answer, please give me a compliment and attention. I sincerely hope that I can help my friends by answering. Finally, I sincerely wish all the friends in the world good health, happy family, all the best and make a fortune every year. Congratulations on getting rich, thank you!
Invited to answer questions in this industry.
Routers can't surf the Internet every once in a while, but they can be used again after power failure. Actually, there are many reasons for this result.
There is a device with a fixed IP under the router, but the IP conflicts with the router, which may cause all terminals under the whole router to be unable to access the Internet.
At present, our router is the core equipment of home Internet access, and all terminals access the Internet through the router's intranet.
However, if a terminal under the router has a fixed IP, but this IP is the router's intranet IP, IP address conflict may occur, resulting in the router being unable to access the Internet.
For example, your router's intranet IP is 192. 168. 1, but another device in this network has this IP, so it may happen that the router can be used for a period of time after restarting, but it cannot be used immediately.
To solve this problem, you can try to modify the router's intranet IP. For example, your original IP was 192. 168. 1, and the login wireless router was changed to 192.5438+068.2. 1.
2.4G WIFI interference may also cause the terminal to be unable to access the Internet.
At present, the interference problem of 2.4G WIFI can hardly be solved. Domestic optical fiber penetration rate is too high, and every family has a wireless router. However, the signal diffraction ability of 2.4G WIFI is strong, and it is easy for neighbors' 2.4G WIFI to interfere with you. It is recommended to buy a dual-band wireless router and try to use 5G WIFI to surf the Internet.
Of course, some low-end mobile phones only support 2.4G WIFI, so you can only try to modify the channel of 2.4G WIFI. But now, to be honest, there is basically no clean and interference-free channel.
Problems with the router itself may also cause it to be used for a while after restarting, but it cannot be used.
The standby capacity of the router itself has an upper limit, which is related to the hardware configuration of the router. If the performance of the router itself is not strong enough, too many connecting terminals may cause the router to fail to work normally.
In addition, the thermal stability of the router itself may also be due to reasons such as too long service life, too closed router position and too dirty router, which leads to the router not working for a long time.
It is suggested that the wireless router should be placed in an open place, with no obstacles around it. One signal is better, and the other router has better heat dissipation. Generally speaking, the router is recommended to be placed in the central area of the room.
Plug-in problems may also cause routers to be often unavailable.
Routers need a relatively stable voltage. Some inferior patch panels may have unstable voltage, or routers may not work normally because of voltage problems. This is also a question to consider.
It is also necessary to buy better jumpers for wireless routers.
In a word, the wireless router can't work normally after working for a period of time, and it works well after restarting, but it can't work normally soon. There are many problems that may lead to this phenomenon, but the most common problem is the wireless router. The biggest possibility is that you need to buy a new dual-band wireless router with better performance.
