The computer can be turned on and can use wifi, and it will not be used after a few minutes

1) If it is a problem with the broadband itself, first directly connect the broadband network cable to test, if it is a broadband problem, contact the broadband customer service to solve it.

2) If it's a problem with the router, if it can be used originally, it can't be used for the time being, my own practice is to disconnect the power of the router and plug it in, and I'll take a look. In there is a factory reset, from the new strict according to the manual settings can be used, I don't understand, it is not recommended to set it at will (this is under the premise of the correct physical connection, sometimes the router is slow or failed to find the IP address, not that the router is broken).

If it can't be solved all the time, it is recommended to call the customer service of the router, they have **** guidance, I encounter a problem that I can't solve by myself, it is very useful to consult the advice they gave, and they will give the correct advice for your settings or operations.

3) If you turn off the wireless switch, turn it on, if it is a wireless connection with software, it is normal for the software to be difficult to use and often have problems, there is no better way, use a router. In addition, it is caused by the network card driver is not or is not suitable, and whether there is a problem with the network cable interface or network cable.

4) If it is caused by a system problem, it is recommended to restore the system or reinstall it.

5) If you have any questions, please ask me.

The solution is very simple, this is the problem of the wireless network, you can change a wireless network connection, I used to be the same as you, and asked: But my home is just this wifi.

It is a problem with the unlimited NIC driver of the installed system, and it is recommended to reinstall the driver or reinstall the system.

It's okay with this computer, it should be a problem with the wireless router.

Click "Start Setup Destroy the Internet Connection", right-click on the dial-up icon, select the Properties option, remove the checkmark in front of the prompt name, password and certificate, and then save the modifications. Copy the dial-up connection icon on the desktop or in Network Connections, then right-click on the taskbar, select Properties Start Menu Customize Advanced, and then open the program Launch.

Note: rasdial(dial-up command), adsl(dial-up name), user(wideband username), password(wideband password).

Step 2: When you have written the command in its entirety, save it as. BAT format. than the posture is like Yu Hu you save into.

Step 3: Put it in Start--Program-Startup, set it to the system startup item, enter msconfig in Runtime, and tick the startup item of the dial-up software.

I don't know, because I don't have a computer yet.

In this case, you can open the startup item in the 360 Security Guard optimization acceleration, and prohibit some programs from booting in it, so that the connection is faster.

It takes long after the laptop is turned on to connect to wifi

First of all, check if the wifi signal is not very weak, if the signal is weak, the connection will be slow.

You can consider replacing a better wireless router.

If the connection to wifi is slow, it may also be a problem with the wireless network card of the computer, you can update the driver first. Or replace the wireless network card.

In addition, observe whether the computer is very slow to respond, which will cause the application to open very slowly, so even the wifi is very slow.

In this case, you can consider reinstalling the system. Or replace the SSD and increase the memory module.

The speed at which your computer runs.

It takes time for the wireless network card to connect to the network router to assign an IP, so it will be faster to set a static IP to the router and bind the IP to the network card of the desktop. In addition, if the computer configuration is not high, or the network card is poor, the computer also has a process of starting the network card, and it doesn't take a minute to do so, and so on.

The wireless network card is installed later, and the wireless network card can only be recognized and driven after the system is booted, so the wireless network connection will be relatively slow, which is normal.

1. Try restarting the wifi and reconnecting.

2. If you still can't access the Internet after restarting the connection, open the wifi settings webpage, if the settings webpage can't be opened, there may be a problem with the wifi settings, try to restore the initial settings: when the wireless router is turned on, press the reset button and don't let go, after 5 seconds, restore the initial settings and re-set the wireless router.

3. If you can open the wifi settings webpage, check the connection status of the WAN port, and check whether the IP address and DNS obtained are normal.

4. If the WAN port shows that it is not connected, check whether the account number and password are wrong, whether there is a problem with the modem and line, and whether the WAN port network connection router is in good contact.

5. If the above method is invalid, find a router to replace the sail, if it is normal after replacement, it proves that the router has a problem and needs to be repaired.

It's not very clear, but there are many possible reasons.

Methods to try:

1. Try a good network cable. If it still doesn't work, it's a problem with your router or computer.

2. In the operating system, match the working mode of the network card with the router, such as automatic, full-duplex, and half-duplex. Different routers have different default rates, so they may have different results. (The probability of a problem is relatively small).

3. Use other computers to connect this cable, if there is no problem, it is a problem with this computer. (There is a problem with the network card or system).

4. Restart the router, if it doesn't work, clear the configuration and reset it to see if it can be solved.

Problems with the firmware of the current version.
