The dial up connection is old and the broadband connection is old.

It has been used for 5 years and it must be a problem of aging equipment and aging lines, I only replaced the cat and router that I have used for more than 4 years last month, and the network cable of the cat to the router, and the ** line of the cat has not been changed. If the equipment is changed, it must be a problem with the line.

Before the change, the speed was slow at 7-10 p.m., but now it is normal.

Summary: The poor performance of the old equipment affects the subcontracting rate and the ability to modulate and demodulate the signal.

Suggestion: Whether it is a ** line, a network cable, or a device, it will affect the performance after a long time, so just change the ** line (it may also be a splitter between ** and the network)!

Hope it works for you...

It should be a problem with the compatibility of the cat, try to change the cat, if the broadband is Netcom, the cat is free to change, you just need to call 10010---0 to manual, consult it.

1.It is possible that the voltage problem causes the broadband modem to restart and cause the connection to drop, you can find a multimeter to test the voltage to see if it is normal to determine whether the voltage problem is caused;

2.Check whether the ADSL or Link light on the broadband modem is solid when the broadband is disconnected, this light indicates the communication status between the broadband device in the operator's computer room and your broadband modem, it should be solid under normal conditions, if the light is not on or flashing, it may be a problem with the line or the splitter, it is recommended that you call the operator's customer service directly to contact and solve.

Win7 system network always automatically disconnects from the network solution:

1. Right-click on the network and select "Properties" to open the Network and Sharing Center.

2. In the Network and Sharing Center interface, select Change Adapter Settings.

3. In the "Network Connection" interface, right-click Local Connection - Properties.

4. In the "Local Connection Properties" interface, select "Configure".

5. In the Realtek PCIe Family Controller Properties. Select "Power Management" -- uncheck "Allow the computer to turn off this device to conserve power".

While using win7, there are many network problems, and frequent disconnection from the network is also one of them. If you have a similar problem, you can try it according to the solution in the tutorial, hoping to solve your network automatic disconnection problem.

It has something to do with the line in your home.

This situation is that the broadband is frequently disconnected, the reasons are as follows, 1 The plug in the line, the connector has a few bad places, after finding, reconnect it.

2. The temporary solution is to buy a voltage regulator caused by low voltage.

I think you're asking two different questions, one, the network is unexpectedly interrupted (disconnected). 2. Why do I need to restart my computer to dial in again?

1. Disconnection problem: First of all, in addition to the computer and modem failure, the possible reasons are: line quality problems (more likely), operator DSLAM or BAS equipment problems.

2. Restart the computer to dial up again: When the network is abnormally disconnected (i.e., abnormally offline), the operator's equipment will automatically judge that the user is in an abnormal interruption state, and will require the user to dial up again after 1 minute to access the Internet. So, you don't have to restart your computer, wait 1 minute and try again.

Call 10000 and ask if telecom is a line problem.

Looking at the indicator light on the cat, the ADSL flashing is a problem with the line.

Back up, format the hard drive, reinstall the system.

There may be many reasons, first, check the antivirus, like you said whether it is poisoned; Second, check whether the network cable connecting the computer to broadband is a quality problem of the network cable; Third, check the ** line; Fourth, see if the broadband cat is too hot after connection, sometimes too hot, the device has a self-protection function, it will be disconnected and restarted, try another cat; Fifth, observe the cat's indicator light prompt, according to the prompt light to find the reason, such as disconnecting, and then redialing, if you can't dial up, there will be a prompt, write down the prompt code, and carry out the corresponding operation. Sixth, find the operator and find the problem, which may be a matter of signal quality.

Is the computer broken? Go to the place where the computer is repaired to see that the cat can't be broken If the cat is broken and can't even connect to the Internet at all, the machine is not likely to be poisoned Poisoning can not appear in the disconnection It may be stuck or something, you can ask.
