Why is it slow to connect to wifi when the laptop is factory reset

There are several possibilities and workarounds:

1. Take a look at which protocol is supported by the wireless network card of the laptop that cannot be connected to the wireless network, and then take a look at which protocols are supported by the wireless router. I guess it might be that the wireless router doesn't support your wireless card protocol. If this is the case, it depends on the router, if the router is on the higher end, it may be that you did not choose to be compatible with all protocols when you set up your router.

If the router is lower-end, it may not support the wireless protocol type of your laptop at all, because your laptop is older.

2. System problems. In the past, I have encountered a situation where the Vista system cannot install a network printer when the printer connected to the XP is connected. You're in a similar situation.

It is estimated that the computer system that you can't connect to the Wi-Fi network should be different from the one that can connect to the other one. If it is a system problem, you should consider changing the system. This situation is very common and cannot be repaired by non-quite professional personnel, and it is better to reinstall it.

3. The WZC service is not started. Open Control Panel--- Management Tools --- Services, find Windows ZeroConfiguration (WZC), and right-click to start it.

4. Router setting problems. Set up your router again. Reboot the router multiple times or do a factory reset if necessary. Remember to turn on DHCP, otherwise you will not be able to dynamically assign IP addresses.

5. The firewall level of the machine that cannot be connected to the wireless network is too high, and the level should be set to medium.

The first is more likely.

Update the driver of the wireless card.

There are several ways to try it:

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. There is also the occupation of bandwidth, such as opening many network programs at the same time, network sharing, etc., a part of the bandwidth must be divided;

4. Use some software to clean up the Internet cache files and system junk files;

5. Control Panel Internet Options: "Advanced" "Reset Advanced Settings", "Reset";

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 still doesn't work, that is, the installed system is not good, and when choosing a system, you can choose a more formal type like a greenfield system.

This should have nothing to do with the system.,It may be the reason of the computer itself.,Is there anything wrong with the installed system?,Is it genuine.。

Laptop goes to network management, find your router name and delete. If it doesn't work, use software such as the driver wizard to update the driver.

Update the wireless card driver.

Do you turn on wifi or receive wifi for other people on your laptop?

Or is it the net you rubbed with your laptop.

WiFi is unstable, sometimes fast and sometimes slow, it is recommended to exclude as follows.

First, the software aspect.

1. It is recommended to reduce the startup items and avoid running multiple programs at the same time.

2. It is recommended to use an external power supply as much as possible and adjust the power supply option to high performance, so that the CPU can reach the full frequency state.

3. It is recommended to turn off the windows update function of the operating system, as frequent updates will cause a slow impact on the system.

4. It is recommended to use some optimization software to optimize the system.

5. If the above operation is invalid, it is recommended to reinstall the operating system and observe.

Second, the hardware aspect.

1. It is recommended to try to upgrade the memory to speed up the operation of the machine.

2. If the above methods are invalid, then it may be a hardware failure, and the machine needs to be brought to the service center for testing and judgment.

Summary.

There is no internet connection after clicking on the bottom right corner of the question.

You're a desktop computer.

You need to plug in a network cable.

It's good to ask questions, and it's right to use mobile phones and computers.

Changing hard disks, the wireless speed slows down, this has not been encountered, but the wireless network may be slow for one reason.

1, your wireless is used by multiple devices, so it is not slow to blame 2, you have a network problem, that is, the network provided by the network operator is unstable 3, is your cell fiber, if it is normal4, when changing the hard disk, you may touch your wireless network card, resulting in bad contact with the above line (the wireless network card is generally connected with two antennas) or the wireless network card is damaged.

5. There may be a problem with the system, but there should be no problem with the driver.

If you replace the hard disk, the original program has also been redone, so if you confirm that the external reasons such as network cables have not changed, it is almost always a program problem, re-update the driver, or reinstall it.

The laptop uses wifi to access the Internet, and the speed is relatively fast at the beginning, but after a period of time, the speed slows down, and the QQ old disconnection. There are multiple possibilities for your situation. 1. Same as the brother above: Someone has joined your network and occupied you.

It may be due to your local network environment, or you should update the wireless driver to try.
