2. Most of them are line problems. Changeover, network cable. The problem is still to change the ** line.

3. The problem is still to check the contact of the junction box. Cats can borrow one from a classmate. It's the cat's business when the problem is solved.

4 No problem with the drive, no problem with the line, no problem with the cat. Then it depends on the network card. Again, we have to use the substitution method. Find a network card and try to replace it.

5. If there is still a problem, the function hopes and reinstall the system.

6. When installing the system, repeat the recitation of Amitabha. . .

7. Let's find the customer service staff of Netcom to take a look. They must have looked it up with their notebooks. If the line is fine, people don't care. If there is a problem with the line, let them fix it. If you have no problem, go to the maintenance department like a computer.

Netsplit is a loss of contact between two IRC servers when using an Internet Multi-Line Chat (IRC) network.

My family is also this equipment, there are only two reasons, one is that the plug is not plugged in well, and the other is that there is a problem with the wireless part of the device, for these two problems, you can find telecom personnel to solve it, it is best to ask them to change the equipment for you!

This is normal,1 Because your wireless does not have a fixed IP address, turn on the wireless first, and then turn on the desktop and be squeezed out.

2. Because your wireless network card is not strong, it has been squeezed down by others.

3. Your wireless network card and router don't work well together!

Solved: Right-click on the Wi-Fi connection and select Repair. If it doesn't work, you manually add the IP address, the general router is the gateway, the IP is set, and the middle is that it doesn't work anymore, your wireless signal is not matched with your wireless network card, and the wireless signal has.

DNS you check your city on the Internet, add it OK, you have to see what the reason is, if it has been stable 54Mbps, it means that the signal quality is fine, there may be some setting problems, such as the router's DHCP automatic allocation IP lease is not set too small, automatic renewal is not set.

If the signal is big or small, the signal quality is not good, the wireless network signal is more sensitive to obstacles, if there are 2 walls, it is easy to drop the line, change to a high-power router, or install a gain antenna to improve the signal.

I set the router to a static IP, so that there will be no connection for a while and then the network will be disconnected.

Routing setting issues, reset it, reset it.
