How to upgrade the wireless network card at home? Want to upgrade your laptop s wireless card?

Many friends will encounter a bad signal of the wireless network card at home, let me introduce the reasons and solutions for you!

1. The position of the wireless equipment is incorrect; Generally speaking, the wireless router should be placed in the middle of the room to get the best results in terms of signal coverage and transmission speed. Because the signal of the wireless transmitting antenna on the router is a circular range, if the wireless router is placed in a corner of the whole room, it is equivalent to wasting half of the space in vain, which naturally seriously affects the coverage of the wireless signal, and the range of the wireless network has also changed from the default entire circle to half a circle, which greatly reduces the wireless performance;

2. In addition, there will be many corners of the wall in the room where we are, and each corner will affect the transmission of wireless signals, so we should try to avoid corners when designing wireless networks and equipment placement. This coincides with the aforementioned placement of wireless devices in the middle of the room, and the two are unified;

3. The wireless router itself is unstable; In this case, we can put the computer and other Internet equipment as close as possible to the wireless router, or take the wireless router to the PC with the wireless network card plugged in, reduce the distance to check the stability of the wireless signal;

4. If the connection speed and signal strength are still not ideal, you need to start with the wireless router to check the stability, the most common way is to go to the official homepage of the wireless product manufacturer to ** the latest patch package or firmware driver. The upgrade driver method is especially effective when the signal of the wireless router is unstable or the wireless network card automatically drops every few minutes;

5. The wireless network card itself is unstable, if your computer is using a wireless network card to access the Internet, it may be that the current wireless network card driver needs to be updated, you can install the latest driver on the official website according to the brand model;

6. When two computers in a wireless network or a wired network are transmitting data, if the network card of one computer is set to simplex or the transmission speed is 10m, and the network card of the other computer is duplex or the transmission speed is 100m, then there will be two network cards frequently negotiate the connection speed and working mode and cannot transmit normally or frequently disconnect, and some users may set the transmission speed to 54m on the wireless router. However, the transmission speed of your wireless network card is only 11M, and at this time, there will be a situation where the two negotiate the working frequency and mode to cause the connection speed to be slow or unstable;

The above are the reasons and solutions for the instability of the wireless network at home, I hope it can help you!
