The wireless network card can access the Internet, why can t my wireless network card work?

Yes, what is the wireless network card if you can't access the Internet?

The cause of this problem is that the network adapter driver is abnormal, and the problem can be resolved by restarting the driver, as follows:

1. First of all, right-click the "Start" button and select "Device Manager" as shown in the image below.

2. Second, find the NIC device, as shown in the red box in the figure below.

3. Next, right-click on the NIC device and select the "Disable Device" option, as shown in the figure below.

4. Then, right-click on the NIC device again and select the "Enable Device" option as shown in the image below.

5. Finally, it can be found that the equipment has been running normally, as shown in the figure below. In this way, the above problem is solved.

1. Here is a question first, that is, do you confuse the wireless network card with the wireless network card, the wireless network card is the wireless form of the ordinary physical network card, and you can access the Internet through the wireless AP or wireless router of the LAN as the Internet exit without connecting the physical twisted pair; But the wireless network card is a kind of device that can directly access the Internet through CDMA1X or GPRS network, as long as there is a ** network, this device is like a wired "cat" with you at any time! You said that your ** card is connected, that is, you are using the CDMA1X network to surf the Internet, and the GPRS network makes it mobile!

2. Just look at your problem phenomenon, there are three possible factors:

a.It's a signal problem, CDMA is faster than moving, and the traffic is large, but it is undeniable that the signal coverage is not very good, and the first thing to do is not related to the bandwidth, so you don't need to consider the bandwidth problem when considering the signal problem, you can take a look at it in another place;

b.The compatibility between the card and the machine, but I don't feel like it, you can uninstall the driver and reinstall the software to see or put the card lead on other machines to see, and the elimination method is to see if it is a card problem or a compatibility problem with you and it;

c.It may be in conflict with other devices on your machine, look at the status of the device manager's card, mainly the collision signal.

You'll have to look at the Wi-Fi connection and see what information it prompts, and then I'll be able to help you out.

1.There is no Wi-Fi.

2.There is a problem with the configuration of the wireless NIC.

Let's add more.

The wireless network connection does not work, it may be caused by these factors! Teach you to solve it easily!

It may be due to the lease period of the router's DHCP service setting, or it may be that the IP address will be renewed after the lease expires, and the router and NIC negotiate something to go wrong, and the lease cannot be renewed, resulting in the IP address being withdrawn. Try setting the rental period a little longer to make this problem less likely, home routers can usually be set to 7 days, but some smart settings can be set to 1440 minutes (i.e. 24 hours).
