Do you still need a router for a wireless network card for desktop computers 20

Don't use a router to see if your cat is wireless. There are two types of wireless routing:

One is what we often call a wireless LAN, that is, in a local area network, there is a router or AP that transmits wireless signals, and the wireless network card of the desktop or laptop needs to receive signals from the router or AP**, which is the need for a router. (This is generally the case with your desktop).

The other is a wide-area wireless network, which is generally your computer can be connected to the Internet, just like our mobile phones, and you can play when you arrive. This is generally for notebooks, because the portability of notebooks is much more convenient than desktops, therefore, the wireless network card of the WAN is generally for notebooks.

Of course you need to, if you don't want to use a network cable, buy a wireless router, the router is ordinary, there are no special needs.

The wireless network card does not need to be routed.

But that's not to mention slow.

Also dropped the line of Tehuan.

It depends on what kind of cat you use, if there is a cat with routing function, you don't need to buy another router; If you use a cat without a routing function, then you have to buy a separate router.

Desktops are not recommended to use a wireless network card if it is not necessary, a word is quite slow.

See if your cat is wireless.

There are two types of built-in wireless network card interfaces in notebooks, one is mini-PCI and the other is PCI-E.

1. Taking Intel chipset as an example, generally speaking, old laptops with Intel 855 PM GM and Intel 915 PM GM chipsets have a mini-PCI slot for the wireless network card, as shown in the following figure

2. Starting from the laptop with Intel 945PM GM chipset, basically most laptops use the mini PCI-E interface, as shown in the figure

Since desktop computers do not have this interface on the motherboard, the built-in wireless network card on the laptop cannot be used.

Desktop routers can be wired, not wireless.
