Why do you always say that there is a problem with the network, and you can t connect, please 3Q

Let me tell you, no matter when you wait until it is useless, you have to wait until every Tuesday after the DNF update to play, so that the Internet connection will not be interrupted, you know? That is, it will have to wait until the next update.

Causes of unstable network signals. If the DSL light flashes, it means that the signal is unstable, and it is not connected to the Internet at this time; The signal is stable and the light will stay on. If the cat is not turned off for a long time, there may be a signal that cannot be stabilized; The staff changed the cat to rule out the possibility of the cat being out of order.

The landlord is embarrassed in this situation, because generally only when the network is disconnected and there is no signal at all, the staff will check the line because of the line failure; If it's just unstable, but it can be connected, they generally won't overhaul the line.

Sometimes bad weather such as heavy rain, thunder and lightning will cause certain interference to the server and affect the line transmission.

Many times, the computer does not have a network, and it may not be a problem with the computer, but a problem with the network in this article. Therefore, first of all, you should look at whether the router and other network equipment are operating normally, the computer cannot access the Internet, and other settings connected to the same network, such as other computers and mobile phones, can be connected to the Internet. win+r to open the run box, enter enter to open the device manager, check whether the network adapter has a yellow exclamation mark, if there is a need to install or update the network card driver.

First check whether the connection of the hardware device is normal, then boot it up to check whether the network settings are normal, analyze the specific prompt information, modify the items that need to be modified according to the prompts.

Is there a router? If there is, then there are many problems. Is that all there is to it when plugged in directly? You didn't make it clear. If there is no network, the router is generally not set up.

That should be your computer malfunctioning, check it carefully for yourself to see if it is broken.

You reinstall the system! I've encountered this before, and I didn't know after asking a lot, so I had to reinstall the system.

1) If it is a problem with the broadband itself, first directly connect the broadband network cable to test, if it is a broadband problem, contact the broadband customer service to solve it.

2) If it's a problem with the router, such as teasing the fruit that can be used originally, it can't be used for the time being, my own practice is to disconnect the power of the router and plug it in, and I'll take a look. In there is a factory reset settings, from the new strict according to the manual settings can be used, I don't understand, it is not recommended to set up at will (this is under the premise of the correct physical connection, sometimes the router is slow or failed to find the IP address, not that the router is broken).

If it can't be solved all the time, it is recommended to call the customer service of the router, they have **** guidance, I encounter a problem that I can't solve by myself, it is very useful to consult the advice they gave, and they will give the correct advice for your settings or operations.

3) If you turn off the wireless switch, turn it on, if the mountain Luzi is connected to the wireless with software, it is normal for the software to be difficult to use and often have problems, there is no better way, use a router. In addition, it is caused by the network card driver is not or is not suitable, and whether there is a problem with the network cable interface or network cable.

4) If it is caused by a system problem, it is recommended to restore the system or reinstall it.

Write the correct IP address and DNS server address, the general DNS server must be the same in the same LAN, the main problem is the IP address: the IP address is generally: or.

As for whether to fill in 1 or 0, it depends on what the router is set to, or to see if the computer that can access the Internet is 1 or 0, just follow the setting. Then press OK and you're done.

Responsibilities of the operator (transmission and switching network failure): The operator must ensure that the signal quality to the user (bandwidth, bit error response rate, signal-to-noise ratio, transmission rate, signal level, input and output impedance, signal stability, and stability of input and output impedance meet national standards), specifically**: China Telecom 10000 Netcom 10060 Tietong 10050.

The power supply of general auxiliary equipment (routers, network switches, cats, etc.) is a rectifier power supply, without voltage stabilization function, with a large ripple coefficient (which may be caused by the drying up of the filter capacitor), and the load capacity is also poor; If the equipment does not work due to heat, special attention should be paid to monitoring during operation.

Due to the overvoltage, low voltage, excessive voltage fluctuation, overcurrent, and heating of the equipment, the overheating protection action will cut out the fault and the equipment will be withdrawn from operation (i.e., it will produce slow, delayed, repeated start, delay, disconnection, interruption, automatic shutdown, crash, etc.).
