Causes of router drop

Question 1: What is the reason why the router keeps dropping? It's not that your router is dropping, but that your network is unstable, and the official server is always dropping. Please contact your network administrator and tell him that the network is always dropping because of instability, so adjust the network and hope to adopt it.

Question 2: Why is the router always dropping? This problem is easy to solve:

Keyword channel interference/wireless router signal interference next door

Solution:

Enter the wireless router/wireless settings section/ The wireless mode is changed from 11bgn mixed to 11g only

Secondly, the problem of ip conflict

Solution: Turn on the dhcp service for your router (if the router in front turns on the dhcp service, the router can be turned on, and the lanip address must be changed. You don't have to turn it on)

dns Fill in a local dns. If the router is in front, but this is not filled in,

Question 3: What is the reason why the router is often disconnected after changing the router? mw3r, right? It should be a router problem. You can contact the seller to try the firmware upgrade.

Question 4: What should I do if the router is always disconnected, but it will be fine if I restart it? Wired or wireless? It's normal for the router to be disconnected, or it may be a bad heat dissipation. Look at it in another place, and sometimes it will be a crash. Are you Tengda's router? It's ASUS or something like that. This kind of home-use tp-link is relatively stable and inexpensive. This simple route is generally not a setup problem, and it has a lot to do with the quality of the hardware itself. It's really not possible. I suggest you change it, or just change it to something better.

Question 5: What is the reason why the router's wireless connection is often disconnected? According to your description, The following reasons are analyzed:

Poor driver compatibility

The driver problem is the most common problem for users who are generally disconnected. After a period of normal use, the wireless router is inexplicably disconnected. This kind of problem is caused by the fact that most users use the wireless network card driver that comes with the system when installing the operating system, especially some pirated XP systems, and the driver that comes with it is either too low or unstable.

Driver problem is a common cause of frequent wireless disconnection

When users encounter such problems, the first thing to consider is the receiver, that is, the laptop or the wireless network card connection. Whether it is a Centrino notebook or a desktop with a wireless network card, the network link may be wrong due to the compatibility of the network card or the driver problem.

first of all, we should confirm whether the network card itself has quality defects, and then check whether the driver of the network card is normal or the driver version is too old. If the notebook uses a wireless network card and routing connection, most different brands of wireless network cards and routing are compatible except the wireless suit, but it does not rule out that the interoperability between a few products is not ideal. You can try to search the network card model you use to find the wireless routing with poor compatibility on Baidu or Google. Are you in this line to find out the reason for the disconnection?

Reasons for frequent line disconnection: virus is at work

Computer poisoning is also the main reason for frequent line disconnection. If there is a worm of ARP spoofing type, when enough virus packets are accumulated in the network, a large amount of traffic will impact the port of broadband router. When the traffic is too large, the router port will protect itself, that is, it will automatically close the port to make it invalid and discard all virus packets. At this time, the client computer will be disconnected and unable to connect to the external network; However, when the broadband router closes the port by self-protection, the virus packets are discarded, so the port will automatically return to normal in a short time (within one minute), which is why the reader returned to normal about one minute after encountering the actual disconnection problem.

virus

when the fault is caused by ARP spoofing virus, we should first install system patches for the operating systems of various client computers to make up for various loopholes, then install anti-virus software to update the virus database to kill worms, and if necessary, we can also combine arp -d to clear ARP cache information to restore the normal network. Only after the virus is completely removed can the network be restored to normal, and the problem of automatic disconnection mentioned above can be solved. Of course, for some severe ARP viruses, we can only use tools to solve them, such as installing an ARP firewall on this machine or limiting the attack and spread of the virus through the binding MAC function of the router. These are very effective preventive methods, which have achieved remarkable results in the actual use and maintenance of the author.

For wireless routers with many users, the attack probability of this virus will be very high, so effective virus prevention will avoid router disconnection or even more serious failures. For experienced users, when they find that even accessing the local area network or routine operation is slow, they will realize that this is probably caused by a virus. At this time, we can use the new anti-virus software to kill or PING the gateway to locate the problem by checking the traffic.

Reasons for frequent disconnection of wireless route: setting deviation

Of course, if the disconnection problem is not caused by virus, then the most likely problem is the setting of software parameters in broadband router. We can go to the management interface of broadband router. Compare each parameter setting information one by one, especially "network parameters->; WAN port settings "to see if it is set to" connect on demand, automatically connect when there is access, and automatically disconnect and wait for x minutes ". If this is the case, the broadband router will dial up when someone in the intranet wants to access the external internet, and it will automatically disconnect when there is no network access within x minutes. We can modify it to "automatic connection, automatic connection after startup and disconnection" to solve the problem and eliminate the phenomenon of automatic disconnection and disconnection.

Wireless setting problems can also lead to dropped calls

Improper software setting may also lead to the phenomenon described by readers, as mentioned above, when the dial-up parameters of WAN port are set incorrectly, when the network is not available within five minutes ... > >

question 6: why does the wireless router always drop the line? there are many factors that cause the wireless router to drop the line and disconnect, which are mainly divided into internal factors and external factors. The following two factors are analyzed:

A, internal factors:

The main performance is the quality problem of the router itself, that is, when purchasing, some circuits in the machine have poor contact, which will lead to abnormalities during the working process;

in addition, if the routing line works for a long time without paying attention to the internal cleaning work, dust will be contaminated on the fuselage and enter the machine, which will also cause the router to drop the line frequently.

B. External factors:

There are many kinds.

1. If the location where the routing line is placed is disturbed by electromagnetic waves of household appliances, the signal of the routing line will be disturbed, so that it will be disconnected during use. Because the data and information transmission of routing lines are generally carried out by electromagnetic waves with changing frequencies, if there are strong interference electromagnetic waves nearby, there will be disconnection.

2. If the routing line is used for a long time, resulting in the internal structure temperature rising, it will also be disconnected.

If you use BT to download or play online games, it is certainly not surprising that they are all busy with network speed. Therefore, generally speaking, when using BT to download or play online games, it is best not to open the routing line, which will shorten its life.

Question 7: Why is the computer always disconnected? Is the router broken? There are many reasons for the 1-minute disconnection:

1. External cards are used, which will often happen. You can choose to plug in a USB, install the driver (if it doesn't work properly, click and then continue to the next step until it is completed. It is a process of copying files.)

2. Network cable, it is not surprising if the network cable has been pulled and the crystal head is loose, and this problem will also occur if the network cable is aging for too long.

3. The independent network card is loose. Or the anchor's independent network card slot is too dusty. Use an eraser to wipe the gold finger of the network card. And if there is banana oil (Tianna Water), use a toothbrush to erase the following anchor.

4. The router has a problem, which will occur if it is left on for a long time. There is also the problem of the router itself, which can be solved by resetting the router.

enter 192.168.1.1 (the default IP address, if you can't log in, or the address is incorrect, manually check the router IP address, and open the start menu-Run-cmd-Enter-ipconfig-the router IP address is on the right side of the default gateway) to log in to the router and ask for an account password (this account password usually has a tutorial in the box where you buy a router. If you lose only Baidu's login account password of the brand of the router, the login will generally jump to the running state. Then click "Setup Wizard" in the column. Next, dial in PPPOE mode. Next, enter the account password (the account password for surfing the Internet is written in the certificate for handling business). Then, the next step is to set the wireless settings on, automatically jump to the WAN window and set the disconnected automatic connection. Click "Save". If you need to restart the router, you don't need to pay attention to it. Then click "Wireless Settings-Wireless Security Settings-PSK Password Settings" in the column, save it and then prompt to restart.

5. If the above can't be solved, plug the computer network cable directly into the broadband, then unplug the router from the broadband, and then open the computer's online neighbor-properties-broadband connection-dial-up Internet access (the account password is written in the business certificate) to access the Internet by broadband dial-up. If there is no disconnection for a period of time, it means that the router has a problem, otherwise it is a broadband problem. (The premise is to eliminate the problems of network cable and network card.)

You can also ask the operator to shut down the network, and then use broadband for another 5 minutes to see if it is disconnected. If it is available, you can ask the operator to test it (free of charge) to see if the crystal head connected to broadband is normal.

question 8: how to solve the problem when the router goes offline for several hours? please ask the expert for guidance. . ... a dropped router? Do you really want to ask the router to disconnect frequently ... check the router DHCP settings, how long is the IP lease allocated to you, and the phenomenon is probably DHCP...

Question 9: What is the reason why the router will automatically disconnect after being turned on for a while? Your question is: dhcp server problem:

The usage time allocated to you by DCHP server is 2 hours.

You can use it within 2 hours. If your ip is still online for more than 2 hours, he will continue to allocate it to you. If your ip is not available, it will be allocated to other users.

question 1: what's the matter with the router always getting disconnected from the internet at home? How to solve the problem from what you described, the router itself is unstable. . . Based on these conditions, I can only think that the instability of the router is the main reason for the drop.

a different router is a good choice. The skeleton is less than 1, and it also has wireless. . . . . (It's up to me, I'm just saying)
