After a period of time on the Internet, the network will be automatically disconnected, the dial up

1. After the broadband modem is disconnected, it can be connected normally after restarting, and there are several possibilities for the reasons:

The signal quality of the external network is not good, resulting in the disconnection between the cat and the operator's server;

After restarting, it can keep connecting for a few hours, which means that there is no major problem with the cat, and it may be that the "auto-dialing" function in the router is not enabled;

It is also possible that the thermal stability of the cat device is not very good, and the operating temperature rises for several hours, and there is a crash.

2. Start from two aspects to find the cause of the problem:

Check whether the "Auto-Dialing" feature is enabled on the router. Enter the router settings page, check the "Auto-connect, automatically connect after power-on and disconnection" option in the figure below, select the small circle in front of it, and press OK to save and modify the parameters;

Then restart the router for the changes to take effect. After that, test whether there is still a network disconnection;

If this problem still occurs, you can feel whether the temperature of the cat's shell is too high when the network is disconnected. If it is too high, it means that the thermal stability of the cat is not good. It can be used to cool down the cat equipment;

3. The problem of automatic dial-up connection after network disconnection can be solved by yourself. If there is a problem with the cat, and the cat device and the home network cable part, it belongs to the free service scope of the network operator, and the customer service of the network operator can be repaired, or the broadband cat equipment can be replaced.

1. If the optical modem is under warranty, directly find a dealer or operator to replace it.

2. If there is no warranty, upgrade the firmware first. Its firmware upgrade can be found in its management interface. Or surf the internet from somewhere else** The firmware of this model, according to its description, is upgraded with a PC connection.

3. If it is still unstable after upgrading, replace the power supply with the same voltage (the current should be equal to and greater than its requirements) for testing. Generally, the power supply will mark the voltage, current and positive and negative poles (the positive and negative electrodes must be completely identical).

4. If you replace the power supply or keep restarting, remove the screws at the back. Find a similar section below (CPU for modem).

Plug in the power supply, wait for 30 minutes, unplug the power supply, see if this part is hot, if it is hot, find a small heat sink, and apply heat dissipation silicone to the bottom to test it.

5. If it is still abnormal, the only way to do it is to replace the equipment.

If it is not disconnected, but the computer cannot access the Internet, it may be a problem with the wireless network card of the computer. Yes, you can buy an external one. Hope it helps.

ip dns1 2 gateway netmask set it up mine has also appeared before now it's okay.

This one is so easy! The voltage is unstable! That's the case a lot of times. Just buy a voltage regulator and connect it to your computer! Guaranteed you're okay!

At first glance, the heat dissipation is not good, try to clean the ash.

Or try it with the fan blowing.

Again, it's broken.

Do you have a router in the first place? Every time you are disconnected, if you just restart the modem and you can go online, it is the problem of the modem. If you are using telecommunications, call 10,000 customer service and ask him to exchange it.
