Why can t I connect to broadband on my computer for a while?

For typical line quality problems, it is recommended that you find line maintenance personnel from China Telecom, China Unicom and China Mobile (Tietong) to help you troubleshoot. The other is the voltage problem, but now that the weather is cold, the power consumption should not be very large, of course, this factor is not ruled out.

If you know it, check the ** line at home, and it may be that the ** line is broken. Therefore, it is easy to disconnect from the Internet, but it cannot be used. If it doesn't work, just report for repair, ** through, your network will be positive.

The line problem is not within the scope of what you can handle, but if you have strong hands-on ability, you can also rule out the incoming line of your own home, and it is okay to check it along the way. However, I still recommend directly repairing, ** not through, sometimes there is a signal is generally two cores broken a core,

It's as simple as dragging the desktop broadband connection to the Start Menu - Programs - Startup

Just specify an IP address for the NIC.

1. Change the last number of your own IP. As.

Change the last 5.

Change to no conflict.

The range is 1 254, if it is not yet possible.

2. If this happens if the IP is obtained automatically, most of it is caused by the ARP virus! Install an ARP fireproof strong try.

ARP Firewall.

Special Extended Edition.

Not really. 3. Redo the system.

The reasons for the computer slowness, network failure, instability, stuck, crash, disconnection and so on are none other than the following three links;

1: The reason for the transmission device; the responsibilities of the operator's equipment room and transmission medium (line) unit;

2: Reasons for switching: the responsibility of the operator's computer room;

3: Terminal reasons; The reason for the terminal is the responsibility of the user; Users must ensure that their equipment is in good condition;

The main problem of transmission is to broaden the frequency band and reduce the bit error rate; The problem with terminals and switching is mainly to increase the processing speed of network switches. There's a lot of work to be done in terms of the above three areas of technology. It is a highly technical and complicated work, which requires the cooperation of a professional.

First of all, you must make sure that there is no problem with your computer, and then carry out fault troubleshooting of the uplink circuit; To find step by step, the only thing you can do is the fault problem of the cat, as far as experience is concerned: most of the problems appear on the user's "cat" ADSL (network switch, router, Hubble, etc.); This phenomenon mostly occurs in the summer of high temperatures, and the main problem is: cats (ADSL) run for a long time to heat, and it is enough to solve the problem of heat dissipation

1: Natural heat dissipation: place the "cat" in a ventilated place to facilitate heat dissipation;

2: Forced heat dissipation: install a micro fan to force heat dissipation on the "cat".

3: Your "cat" may have been used for too long, and the performance of the "cat" has deteriorated;

4: If you are doing IT, I suggest you: add a heat sink to the cat's heating device, and you can solve the problem.

You have done both of the above work, and there is no problem, and you can find the operator to troubleshoot.

Off topic: If you ask the operator to change a cat for you, even if you change it, aren't you still a civilian cat? The cats purchased by the operators are generally civilian products, and the quality of the cats is not necessarily ideal, compared with industrial products, and not as good as the cats used in military supplies and scientific research institutes; These manufacturers pay more attention to economic efficiency, the size and appearance of the equipment, and do not consider the heat dissipation of the equipment.

Cats used in special departments: Mechanical characteristics: Electrical characteristics (AC 220V cats): Acid and alkali resistance Characteristics: Insulation characteristics: Temperature characteristics can meet high requirements. Can you spend that money to buy it?

So you still consider:

1: The problem of dissipating heat from the cat;

2: Do a good job in the optimization of your terminal (computer) system;

You can solve the rest of the problems with the operator.

Thank you for my answer!

……>> Hello:

1. Manually specify the IP address, gateway, and DNS for the local connection;

2. The influence of viruses, Trojans, malware and other factors can cause slow network speed;

3. The quality of hardware equipment such as network cards, network cables, switches, routing, and cables plays a vital role in network speed;

4. Internet access, such as peak Internet hours, will also affect the Internet speed;

5. Service providers are also a problem;

6. Delete the network card in the device management, and then reinstall the original network card driver that comes with it is also an idea;

>> If it can help you solve it, please adopt it casually;

Is there a problem with the NIC driver?

In this case, it is generally the "cat" power cord that is not well connected and has a virtual connection; or the network cable is not good at seeping, selling, noisy, and there is a phenomenon of false connection for rent; Then you can find the telecom to see if someone has stolen your tent servant.

Your broadband is broken. It is recommended to reinstall a new one.

Wait for the modem to stop flashing before dialing!

If it's a LAN virtual dial-up, there is a verification process, but you can go online when you verify your username and password!

You can choose to right-click and left-click to open! Then you can see if it opens faster!

Open the Task Manager and see if you have a lot of startup projects. Sometimes there's a lot of stuff, and it's very delayed.

Is your computer configuration a bit bottom?
