How to solve the problem of slow laptop wireless network card.

Is it 3G wireless Internet access, or the wireless network card that comes with the notebook?

A 3G network card needs a good signal, but the signal strength is generally okay now, unless it's remote. The range of 3G signals sent by the operator's base station is generally about 1 km, and the transmission speed of 3G itself is not very fast, about 1 2M speed, but it is definitely enough.

WiFi Internet access also needs a good signal,At the same time, the bandwidth provided by the wireless signal is large enough,And the network card that comes with this book itself also has a certain relationship,WiFiThe signal coverage is tens of meters,And it is the kind that reduces the obstacle as much as possible in the middle,If there are 2 walls in the middle,Then the signal strength is very weak,The same Internet speed will be very slow,If you want to be fast,Just as close to the signal source as possible。

Under normal circumstances, the rate of the network card is automatically adjusted, and it can also be manually adjusted to 100M full-duplex mode, but it has little effect, but it can also be tried.

3G and the like depend on the distance between you and the base station, the signal is good and the speed is fast, and the speed is slow, so you can use the 3G Internet service of which operator if the signal is good.

This is mainly a problem with the network card, it is recommended to change the network card, generally speaking, the telecom will be a little better, but in general, the wireless network card is slower than broadband.

The reasons are as follows: 1. The aging of the router, serious heating, too high quality and materials, too far away and too many partition walls may also lead to slow down the network speed.

2. The network speed is slow due to congestion of the wifi channel and mutual interference.

3. Bluetooth, wireless mouse and keyboard, wireless key touch headphones, microwave ovens, wireless game controllers and other new wireless peripherals and other new wireless peripherals work in the G channel.

4. The wireless router may be close to the electromagnetic equipment, and there is a possibility of signal attenuation and interference.

Today's laptops can be connected to Wi-Fi so that people can work and watch movies anytime, anywhere. What should we do if the laptop wireless network is too slow? Here's the learning.

The hotkey tone key on the button dial turns on the wireless function by pressing an additional wireless switch. (Some laptops may have heavy wireless switches, which also need to be turned on) The wireless LAN driver did not successfully install the wireless LAN driver in the PC Device Manager. Solution:

Left and right click on your computer, select Properties, and you can click Device Manager. Normally, there is a wireless network card adapter. If not, the wireless network card driver in the computer device manager has not been successfully installed, and the installation is sufficient.

The laptop wireless service feature is not turned on. Solution: Select the control panel on the computer, select Manage on the control page, select Services on the Management page, select Services on the Management page, and double-click the Launch Service interface.

In order to activate the wireless function of the wireless router, all service interfaces have been turned on, allowing SS ancient broadcasting of the wireless network function. The wireless router signal is not good, resulting in the computer's wireless network cannot be searched. The wireless router is faulty or the wireless router is not set up properly.

Solution: It is recommended to change to a wireless router, but you can also try to restore the router to factory settings and set the router again. Try it.

First of all, open the preferences of the Mac system, you can click on the Apple icon in the upper left corner of the screen, and then click on the [System Preferences] bar. 3. In System Preferences, please find and click to open the [Network] management function. 4.

Next, in the network management window, please select the WiFi wireless network bar on the left, and then click the [Advanced] button. 5. Then in the wifi wireless network setting window, please click the new column at the top, as shown in the figure. 6.

Next, under the newly opened large column server, please double-click the new column that is currently automatically obtained with the mouse to enter the mode. 7.It is recommended to click on this rush address here.

8. Return to the network management window, click the "Application" button, and save the previous modifications. 9. After such a setting, you will find that the network speed is faster than the original setting when you surf the Internet on your Mac computer or update in the App Landscape.
