Question 2: Why does the computer always prompt that the network is abnormal? Cause: It may be caused by network instability!
Solution:
(1) Download qq Doctor and patch it!
(2) There is a network abnormality in general wired connection, which is probably an IP address. It is recommended to use 360 antivirus.
Question 3: Why do network anomalies always appear? It is most common to see whether the network cable is connected properly or the crystal head is in poor contact. Then it may be poisoned. It is generally no problem for the next 360 security guard to kill. The firewall is set incorrectly. If you are with others, others may be poisoned and affect you. You can enter CMD at start-run, then enter arp -a and press enter to see how many addresses appear in it, except 192. 168。 *。 If there is an address other than 1, the computer is poisoned.
Question 4: Why does the computer show that the network is not normal? Just try it a few times with the 360 first aid kit. That's what I do.
Question 5: Why does the Internet TV at home always have network anomalies? Main reasons and solutions:
1, caused by a problem with the network settings of the TV; You can enter the network setting interface and try to reset the WiFi signal connected at home.
2. If there is a problem with the router settings or the router fails, you can restart the router to solve it. Or restore the router to factory settings and reset various network parameters to solve the problem; If it is a router hardware fault, you need to contact after-sales maintenance or replace the router to solve it.
3. Whether the network line and server of the network service provider are interrupted or damaged, so that the router cannot connect to the network. In this case, the TV will be disconnected from the network, so it is necessary to contact the network service provider to solve the network transmission problem first.
4. It is also possible that the network is abnormal due to the problem of TV system. You can restart the TV to solve it. If necessary, you can enter the system setting interface to restore the TV system to the factory setting state or upgrade to the latest version.
5. After the above problems are investigated, the TV still can't surf the Internet normally, which may be caused by the failure of network module, antenna, internal circuit or motherboard, etc. It is necessary to contact the TV after-sales service for comprehensive inspection and maintenance.
Question 6: The network is normal, why is there a network connection failure? You may have been hit by a Trojan horse. When you open the folder, you take the initiative to connect to the remote computer.
Download an EWIDO, install it, restart it, press F8, enter safe mode, kill Trojan horse, and then restart it. It should be no problem.
Did you kill him with Evido? Don't just find a Trojan horse killer and sweep it and forget it.
Also, your EWIDO must be upgraded to a lower level before being killed.
Start-run the window, enter "regsvr32 actxprxy.dll" and an information dialog box "DLLRegisterserver in actxprxy.dll succeeded" will appear. Confirm. Run the following commands in turn: regsvr32 shdocvw.dll.
Registrar of oleaut32.dll 32
Registrar of actxprxy.dll 32
Registrar of mshtml.dll 32
Registrar of msjava.dll 32
Registrar of browseui.dll 32
Registrar of urlmon.dll 32
Restart.
These orders are harmless, you can try them.
Question 7: Why does the mobile phone always display network abnormality? There are several reasons why mobile phones always prompt network anomalies:
1, probably because the network signal where the mobile phone is located is not good, you can go online in another place.
2. The mobile phone network setting is incorrect, so you can use another access point to surf the Internet. Compared with CMNET, you can use CMWAP access point to surf the Internet.
3. Broadband may be in arrears, so it is impossible to access the Internet.
4. The 4.WiFi name contains Chinese, which makes some mobile phones unable to access the Internet.
5. There is a problem with the mobile phone system. It may be that there is a problem with the system, which leads to the connection to WiFi but the inability to access the Internet.
Suggested solution:
1, use other mobile phones or devices to connect to WiFi, try to surf the Internet, and eliminate the problems of WiFi itself.
2. Try to restart the router, or restore the factory settings of the router, and then dial-up the Internet again, reset WiFi according to the setup wizard, or replace it with a new router and dial-up the Internet again.
3. Contact the broadband customer service, confirm whether the broadband account is in arrears or not, recharge the broadband, and then try to dial up.
4. If the WiFi name contains Chinese, it is recommended to change it to English or a combination of English and numbers before connecting.
If all the above reasons are excluded, it is likely that there is a long-term problem with the mobile phone system. It is suggested to restore the factory settings or brush the machine to see if it can solve the problem.
Question 8: Why are there many reasons for recent network anomalies? Need to check one by one. For example, the reasons for network anomalies are: (1), your network equipment is aging, which will lead to intermittent network; (2) There are viruses in the machines in the local area network, which will also cause network anomalies; (3), your network cable contact is not good, a little shaking up and down will also cause intermittent phenomenon. Which one is specific, it depends on you to check one by one.
Question 9: What's wrong with the network when computers play games? Network anomalies are mainly caused by line problems, network card problems, network card settings, computer viruses and other factors.
Line problem. First of all, check the wiring at home to see if the indoor connectors are properly connected and whether the wiring has passed through any interference sources, such as air conditioners, refrigerators, televisions, etc. , and try to keep a certain distance from these electrical equipment.
Network card problem. Network cards are generally PCI network cards or onboard network cards. When you choose, you must choose a better quality, otherwise the quality of the internet may be poor. You can use 10M or 10M/ 100M adaptive network card.
ADSL modem or network card setup problem. At present, modems generally have two working modes, one is the normal mode of using dialing software, and the other is the routing mode of automatic dialing. In normal mode, you don't need to set up a modem, just use the default. However, you need to set the routing mode. The MODEM has its own flash memory, which can store the account number and password box settings that are automatically dialed when it is turned on. The most common way of this method is to set the wrong ADSL modem IP address or the wrong DNS server.
There is a virus in the operating system. The virus on the computer can also cause network interruption, so install and use anti-virus software to kill virus.
Question 10: What are the reasons why computers often have network errors? When you use ADSL to surf the Internet, you will often encounter the phenomenon that the webpage can't be opened, the download is interrupted, or you can watch online, the audio stream is interrupted, qq is dropped, and the game is dropped. We might as well assume that the landlord is using ADSL to surf the Internet. In fact, other ways of accessing the Internet often disconnect the Internet for roughly the same reasons as the following. Let's analyze the reason why ADSL dropped.
First, the wiring problem.
First of all, check the wiring at home to see if the indoor connectors are properly connected and whether the wiring has passed through any interference sources, such as air conditioners, refrigerators, televisions, etc. , and try to keep a certain distance from these electrical equipment. You can also replace indoor lines with network lines with stronger anti-interference ability. Make sure the line is connected correctly. After the telephone line enters the home, it is connected to the junction box and then separated by the voice separator. One line is connected to the telephone and the other line is connected to the modem (marked on the separator). At the same time, ensure the communication quality of the line is good, there is no * * * interference, and other equipment that will cause line interference is not connected. And check whether the junction box is in poor contact with the crystal head and whether it is entangled with other wires. If possible, it is best to use a standard telephone line to connect the PC to the twisted pair of ADSL modem. Line is one of the important factors that affect the quality of image browsing. Signal interference sources such as radio transmission towers, welding machines, trams or high-voltage power transformers within 0/00 meters of subscriber cable/KLOC can make users receive clutter offline (copper-clad steel wire has weak shielding and strong signal receiving ability), which will cause strong interference to subscriber lines. The interfered signal often enters from the unshielded downlink part, because the relay cable has a shielding layer, and the interference and influence are very small. If some shielded downlink lines are used in places with strong interference, the speed instability or disconnection caused by interference will be reduced. In addition, the power cord should not be parallel to the adsl line to prevent crosstalk and adsl failure. In addition, there are many other factors that lead to network instability, such as signal interference and software conflict. Mobile phones, which radiate a lot, must not be placed next to ADSL modems, because every few minutes, mobile phones will automatically search the network, and at this time, strong electromagnetic interference is enough to cause the ADSL modems to lose power.
Second, the network card problem
Network cards are generally PCI network cards or onboard network cards. When you choose, you must choose a better quality, otherwise the quality of the internet may be poor. You can use 10M or 10M/ 100M adaptive network card. In addition, many machines * * * like surfing the Internet and use dual network cards, which also causes conflicts. It is also worthy of attention. At this time, you should unplug the network card connected to the LAN or other computers, and only use the network card connected to ADSL for online testing. If the fault returns to normal, check whether there is any conflict between the two network cards.
Third, ADSL modem or network card settings.
At present, modems generally have two working modes, one is the normal mode of using dialing software, and the other is the routing mode of automatic dialing. In normal mode, you don't need to set up a modem, just use the default. The routing mode needs to be set, and the modem comes with flash memory, which can store the account number and password box settings that are automatically dialed when the computer is turned on. The most common method is to set the wrong ADSL modem IP address or set the wrong DNS server. Because for ADSL virtual dial-up users, there is no need to set an IP address, which can be automatically allocated. TCP/IP gateway generally does not need to be set. However, DNS must be set correctly, and you can get the DNS address from the local telecommunications department. In addition, TCP/IP settings are most likely to cause web pages to be unable to browse. Generally, it is set to automatically obtain the IP address, but DNS must be filled in. Others can use the default settings.
Fourthly, ADSL modem synchronization is abnormal.
Check whether your telephone line and ADSL connection are in poor contact, or there is something wrong with the telephone line. Poor-quality phones are particularly easy to drop, but such problems are not easy to find, so you must use a better quality phone line. If you suspect that the splitter or ADSL modem is damaged, please try to connect the external line directly to the ADSL modem without using the splitter. The connection between the splitter and ADSL modem can't be too long, otherwise it can't be synchronized. Excluding the above situation, the synchronization problem can be solved by restarting the ADSL modem.
Fifth, the problem of operating system virus.
In addition to the above-mentioned line conditions, there are also problems with the computer system. For example, the legendary killer caused the LAN to decline. This problem occurs in a large area in China, and the virus is harmful to both the host agent and the router. & gt
