The wireless network card of the laptop is very average. Can you recommend an external wireless network card?

In response to the problem of insufficient performance of the built-in wireless network card in laptops, PHP editor Apple recommends an external wireless network card as a solution. An external wireless network card can effectively improve the quality of wireless network connections and enhance the Internet experience. The following content will introduce in detail the purchasing tips and recommended models of external wireless network cards to help you solve the problem of poor wireless network card performance.

1. The wireless network card of the laptop is very average. Can you recommend an external wireless network card?

Hi everyone, according to the description of the problem, the free wireless network signal in the school dormitory is poor. Due to the relatively remote location of the dormitory, the wireless signal received by the laptop is unstable. Sometimes it can be connected and sometimes it cannot.

How to solve this problem? In fact, it is very simple. We can use a repeater or an external wireless receiver or an AP to solve the problem of poor signal.

Two solutions for your reference:

The first is to add an external WIFI network card to the notebook to achieve better signal reception. Place it in a location with good signal to solve the problem of poor signal.

No driver required, just plug it into your computer and automatically install the driver, which is convenient and fast.

Second method: WIFI amplifier, I recommend using this one. If you are using a wireless network card, then you can only use it on one computer. Then if you use a WIFI amplifier, everyone in the dormitory can use it. , reducing the cost, and you can also connect your mobile phone to WIFI to access the Internet, killing two birds with one stone.

You only need to place the WIFI amplifier where the signal is, such as by the door of the dormitory, or near the window where the signal can be better received, then plug in the power and turn on the WIFI signal, so that laptops, mobile phones and everyone in the dormitory can work together It's morning.

2. Issues related to laptop wired network cards and wireless network cards. ?

Laptops have both wired network cards and wireless network cards.

The usage method is as follows:

The wired network card is responsible for the internal network (LAN) and the wireless network card is responsible for the external network.

Use the wired network card alone, just disable the wireless network card. The wired network card copies files on the LAN faster. Mine is more than 10M, and the wireless network card only copies 1M or more files on the LAN. Published at 12:56 Copyright belongs to the author

10. 노트북 무선 네트워크 카드 구매 및 사용 방법

지속적인 개발로 무선 네트워크 기술의 발전으로 인해 노트북에 무선 네트워크 카드를 장착하는 것이 표준이 되었습니다. 무선 네트워크 카드를 사용하면 유선 네트워크의 제약 없이 언제 어디서나 정보 검색, 이메일 송수신, 화상회의 등을 할 수 있습니다. 그렇다면 노트북용 무선 네트워크 카드를 선택하고 사용하는 방법에 대해 함께 논의해 볼까요?

1. 노트북용 무선 네트워크 카드 구매 시 주의사항

1. 네트워크 카드 표준: 현재 주류 무선 네트워크 카드 표준에는 802.11a/b/g/n/ac 등이 있으며, 그 중 802.11ac가 표준입니다. 전송 속도가 가장 빠른 최신 표준이지만 해당 표준을 지원하는 라우터가 필요합니다. 라우터가 오래된 경우 대부분의 라우터와 호환되는 802.11n 표준 네트워크 카드를 선택하는 것이 좋습니다.

2. 네트워크 카드 주파수 대역: 무선 네트워크 카드에는 일반적으로 2.4GHz와 5GHz의 두 가지 주파수 대역을 사용할 수 있습니다. 5GHz 주파수 대역은 전송 속도는 더 빠르지만 적용 범위는 더 작습니다. 사용 환경이 비교적 개방적이라면 5GHz 대역의 네트워크 카드를 선택하고, 환경이 더 복잡하다면 2.4GHz 대역의 네트워크 카드를 선택하는 것이 좋습니다.

3. 네트워크 카드 속도: 네트워크 카드의 이론적 최대 전송 속도는 일반적으로 150Mbps, 300Mbps, 433Mbps, 867Mbps 등입니다. 구매 시 자신의 인터넷 액세스 요구 사항과 가정용 광대역 조건에 따라 선택할 수 있습니다.

4. 기타 요소: 네트워크 카드의 안테나 수, Bluetooth 기능 지원 여부, MIMO 기술 지원 여부 등도 고려해야 합니다. 안테나가 많을수록 신호가 강해지고, Bluetooth 기능을 지원하면 휴대폰 및 기타 장치의 무선 연결을 실현할 수 있으며, MIMO 기술은 네트워크 전송 속도와 적용 범위를 향상시킬 수 있습니다.

2. 노트북 무선 네트워크 카드 사용 방법

1. 하드웨어 설치: 노트북에 무선 네트워크 카드가 내장되어 있지 않은 경우 USB 무선 네트워크 카드 또는 PCI-E 무선 네트워크 카드를 구매하여 설치할 수 있습니다. . USB 네트워크 카드는 플러그 앤 플레이 방식인 반면, PCI-E 네트워크 카드는 열고 설치해야 하기 때문에 비교적 복잡합니다.

2. 소프트웨어 설정: 하드웨어를 설치한 후 운영 체제에서 네트워크 이름(SSID), 비밀번호, 암호화 방법 등과 같은 무선 네트워크 카드의 관련 매개변수를 설정해야 합니다. Windows 시스템과 함께 제공되는 무선 네트워크 연결 기능을 사용하면 이러한 설정을 완료할 수 있습니다.

3. 네트워크 연결: 설정이 완료되면 노트북에서 무선 네트워크를 검색하여 연결할 수 있습니다. 연결에 실패할 경우, 네트워크 카드 드라이버가 제대로 설치되었는지 확인하거나, 공유기 설정에 문제가 있는지 확인해보세요.

4. 성능 최적화: 더 나은 무선 네트워크 경험을 얻기 위해 채널, 전송 전력 등과 같은 일부 네트워크 카드 매개변수를 적절하게 조정할 수 있습니다. 또한 최신 성능 최적화를 얻으려면 라우터와 네트워크 카드의 펌웨어를 최신 상태로 유지하는 데 주의를 기울이십시오.

즉, 노트북 무선 네트워크 카드를 구입하고 사용하려면 여러 가지 요소를 종합적으로 고려해야 합니다. 충분한 준비와 설정이 있어야만 무선 네트워크의 편리함과 빠른 속도를 제대로 활용할 수 있습니다. 이 글을 통해 노트북의 무선 네트워크 카드에 대해 좀 더 잘 이해하고 활용하시기를 바랍니다. 읽어주셔서 감사합니다!
