If you have a wireless router at home, do you need a network card?

A wireless network card is definitely needed. Unless your laptop already has a built-in wireless card.

If you go to the Internet, there are two scenarios. 1.Internet access is generally available at the hotel.

If there is a wireless offer, you can use a network card. But if you don't, you'll need to buy another SIM card. Generally, China Unicom's CDMA network card is used.

The cost is a little more expensive.

The function of routing is different from that of the NIC, in that the route is transmitted and switched, and the NIC is the receiver.

Look what kind of network card it is. If it's a wireless network card, it's needed. If you travel to other places, you need a wireless network card + Internet card. A network card is like a mobile phone card.

It is definitely necessary, and you can only access the Internet through a network card.

If you don't have a network card, how can you access the Internet! Buy a wireless card!

The router has little to do with the internet speed.

The reason for the network card may be:

1. If other users are surfing the Internet at high speed, the space of the wire box will be occupied, and you will be very stuck when you go to the Internet. This has nothing to do with the computer itself.

2. In addition, it has little to do with wireless routing, unless your routing signal is very poor. When I connected an external wireless card to my desktop, the speed was the same as when I connected the cable.

3. If you use a light brazing, if you use it to return the card, it is the reason for the computer itself, in this case, it is recommended that the software should not be put on the C disk, classified and stored.

4. Line problems, such as network cable is not connected steadily, poor network cable quality, line sequence error, etc.

5. The router runs for too long and overheats internally.

NetworkWhether you use ADSL cat dial-up Internet access or connect to a router to surf the Internet, its network speed is the same as always, without any change. In general, if everyone is connected to the Internet at the same time, the network speed will be diverted, so it is understandable that the network speed of a single user is slower.

With a wireless router and a wireless network card, the device can communicate with the wireless router through the wireless network card, so as to achieve the purpose of accessing the Internet without network cables. There is a laptop with a wireless network card, and you can set up a wireless router directly.

After you power on the wireless router, open the wireless network search of the notebook, you will see a very strong signal with an exclamation mark, and some of the displayed names are the same as the brand and model of your wireless router, depending on the specifics, clicking on the connection will prompt you to set up, and the router sticker that needs to enter the PIN code is on it, and the rest are the same as setting up the router with a network cable.

If you have a wireless router and are connected, that is, if you have WiFi, your desktop or laptop needs to use a wireless network card to connect to the wireless router. Generally, notebooks already have a built-in wireless network card, but desktops generally do not have this function, so you need an external wireless network card to achieve this function.

In other words, a wireless router is equivalent to a signal tower, a wireless network card is equivalent to an antenna, and a device (desktop or laptop, etc.) is equivalent to a mobile phone. In the case of wireless wifi, all three are indispensable.

Hope to help you.

The wireless network card is to accept wireless signals, and there is no need for the wireless network card to work if the router is connected to the wired.

The function of the wireless network card is to receive wireless signals, which is the basis of Internet access. The router can transmit wireless signals, but the premise is that it has a set Internet access number before it can access the Internet through a wireless network card. It's not that if you have a wireless network card and a route, you can access the Internet, and you also need an Internet service provider account, which costs money.

The wireless network card needs to be used with a wireless router.

Routes are divided into ordinary network lines and wireless routes.

Ordinary wired routers only have a network cable interface and need to use a network cable to connect.

Wireless routers generally also have the function of having a wire, which can be used by plugging in a network cable to connect to a wired network card. But with more wireless transmitter capabilities.

The wireless network card does not have a network cable jack and can only receive wifi signals, so you need to use a wireless router to transmit wifi signals.

Why is the network slow to copy?

The principle is very simple, if any machine is used for a long time without rest, the internal will definitely be constantly consumed, which will lead to internal overheating, resulting in a slowdown in network speed.

1. Always open the router, which leads to the aging of the equipment.

Because the router has been in a working state, it has never stopped, so the internal accessories are easy to gradually age, even if it is a hundred megabit optical fiber, it may be "unable to move", it will be easy to appear various small problems of network delay signal, and the network card will be accidentally used.

2. The router is always on, resulting in too much internal cache.

There will also be a cache in the network, and the mobile master introduced that the working principle of the router is to continuously receive and transmit signals, and these caches are gathered with some redundant signals.

So when we turn off the router, it will be able to eliminate these caches on its own, and if we keep the router on, the cache will accumulate more and more, which will cause the network speed to become slower and slower.

If the router at home has a special network card, don't worry too much, you can try to turn it off, rest for a while and turn it on; If it's still very stuck, then simply unplug it and let it go for a day or two to reuse.

During this time, the router can empty the internal cache, and it should be much smoother to use after "taking a break".

It turns out that the router needs to be turned off once a day, no wonder the Internet speed at home is always poor, probably because this small detail is not done well

When you are close to the router, is the network full? If it's full, it means that your internet speed is already low, not fiber.

If it's far away and the router can't cover it, you can buy a Xiaomi pro to increase the coverage area and not change the quality of the network.

It depends on how many megabytes your home network is, how many people are connected, and if you connect more, you will naturally get stuck, and the router is also related, and the 100 Gigabit router will depend on which specific manual you bought, and whether your computer network is limited in speed.

The poor network at home is generally related to this part of the router, and most people don't know it.

It has to do with it, my home network is also stuck, and it may also be the reason for the router.

6m is too slow, it is recommended to upgrade to 100m, and the monthly fee is also very cheap.

Whether it's telecom or mobile, if it's a mobile 100m card, telecom 20m can be played.

It should be that the router has been used for too long, and the general network line is not a big problem, just change to a new router.

[1] Reason: bai

The NIC driver is old or damaged.

The browser is set to the ** service dao option, so the version can't open the web page, the right system has more garbage and web traces, and it has not been cleaned up regularly.

It could be that the DNS server is down.

There is a problem with the NIC hardware.

2] Try the following:

Reinstall the NIC driver.

Reinstall the system, but this method is risky.

Open the Start --- attachment --- run cmd as administrator; Use the ipconfig flushdns command to reset the DNS.

There is a certain relationship, but it is also possible that others have rubbed your net.

Your wifi should set a password, otherwise it will be used by others for free, and the network card may also be the reason, because the network of the telecom back is generally fine. The dual-antenna router has a good signal and is naturally fast, but after all, it is expensive, generally about 100 square meters at home, just buy a single antenna of TP-Link.

The network card is generally the reason for the traffic of your package. Routers don't interfere much. What you have to say must have a certain impact. There is no definitive solution. Let's change the router...

6m?It's too little, and now it's generally more than 50m.

You can just use the computer to dial up the Internet, don't go through the route, see what the situation is, if it's good, it means it's a routing problem, if it's not good, that's the reason for the external network.

Use the telecom network or put the router with a password because someone could steal your network.

It has something to do with network routers.

It depends on whether your network card is bound to your router or not.

Has this always been the case? Or is it episodic?

There is one reason for the poor signal of the routing bai device in the home.

There is too much dust at the DU interface.

zhi causes the network cable to connect to the dao

Bad touch, at this time, I go back to take off the router first, and then need to prepare a container, pour in the plastic bottle cap capacity of alcohol, use a clean cotton swab dipped in a small amount of alcohol to wipe the various interfaces of the router, wipe clean and put it in a ventilated place to dry, and then prepare two cans, use scissors to cut the can body of the can, in a square, and put it on one of the two antennas of the router, so that you can.

You need to have a wireless router, and you also need a computer to install a wireless network card.

How to use: Insert the wireless network card and install the relevant drivers according to the prompts. A computer with a wireless network card will automatically search for the relevant wireless network, and then the user can easily connect to the wireless LAN to achieve file sharing and Internet connection functions by clicking on the connection. When the user clicks on the icon of the wireless network status in the lower right corner, a window appears, which can show the connection speed of the network as well as the strength of the signal.

In this window, you can also find information such as the address assigned to the local area through the router's DHCP and the gateway of the router. The IP address of the NIC is automatically distinguished by the AP.

There are two situations, one is the current mobile GPRS, or you can use China Unicom's CDMA. Then, the monthly subscriptionThe second is that a wireless AP or wireless router is required.

For example, in a local area network, after you plug in a wireless AP or router with a crystal header, your computer will tell you to find a wireless network. Then you click on the connection and let Windows automatically manage the wireless network. In the future, once you are in wireless range, it will automatically connect.

Additional knowledge: Wireless network card is a terminal wireless network device, which is a wireless terminal device used for Internet access through wireless connection network under the wireless coverage of wireless LAN. Specifically, the wireless network card is a device that enables your computer to use wireless Internet access, but with a wireless network card, you also need a wireless network that can be connected, if you have a wireless router or wireless AP coverage at home or location, you can connect to the wireless network through the wireless network card to connect to the Internet in a wireless way.

Wireless network cards can be divided into many types according to different interfaces.

One is a PCI interface wireless network card dedicated to desktops.

One is a PCMCA interface network card for laptops.

Yes, some wireless routers provide wired interfaces, you can connect your network cable to the wired interface of the wireless router and your computer network card.

You need a wireless network card to access the Internet.

If the wireless router has a bridging function, it can be used as a wireless receiver, which is equivalent to a wireless network card, and the specific steps are as follows:

1. Open the browser to log in to the secondary router settings page, take the TPLink WR886 router settings as an example, click Wireless Settings - Basic Settings, click to check to turn on WDS, and click Save;

3. Select the encryption method of the main router, enter the password of the main router, and click Save;

4. Click Restart and wait for it to finish.

2. Open the browser to log in to the secondary router settings page, click Wireless Settings, select Basic Settings, click to check to turn on WDS, and click Save;

4. Select the encryption method of the main router, enter the password of the main router, and click Save;

5. Click Restart and wait for it to finish.

The role of a wireless router is to transmit wireless network signals, while the role of a wireless network card is to receive signals.

If the TV supports wireless function, it can receive the wireless network built by the wireless router, and then connect to the network to use network resources.

Wi-Fi is a technology that wirelessly connects terminals such as PCs, handheld devices (e.g., pads, mobile phones) to each other, and is in fact a high-frequency radio signal. Wireless Fidelity is a brand of wireless network communication technology owned by the Wi-Fi Alliance. The aim is to improve interoperability between wireless network products based on IEEE standards.

Some people refer to a local area network using the IEEE family of protocols as wireless fidelity. Even equate wireless fidelity with wireless Internet (Wi-Fi is an important part of WLAN).

No, the router is fixed, and the wireless network card is portable, but now many public places provide wireless router signals, that is, wifi

Changed to AP mode, but it's a bit wasteful.
