Is the network card casual?

To correct it, Telecom's statement is inaccurate. **Can be played, not necessarily able to surf the Internet. The first case:

You look at the signal light on the cat, most of the time it appears on the cat, when you drop the link or DSL light on the cat (different cats are marked differently) it is not always on and flashing, indicating that the ADSL signal is not normal. So at this time, it can't be connected normally, so the connection is dropped. If this is the case, you need to check your home separator, you can insert the inlet wire directly into the cat to see if the signal is stable.

If it is stable, it can be judged as a separator problem. If it is still unstable, it can be determined that it is a problem with the ** line or the cat, not a problem with the network card or router. The second scenario:

If the traffic light is steady. At this time, you need to check the router, you can enter the background of the router, and look at the network status from the route, under normal circumstances, it will show that it has been connected, and there will be data parameters such as the IP of the external network. If it shows that it is not connected and there is no public IP address, the router is not dialing normally.

You can restart the route test, or you can reset and reset, if the connection still drops after the reset, this is a router problem. The third situation: If there are no above symptoms, then you need to check the network card of the computer at this time.

When you are not connected to the Internet, use one of the network cards you are using to ping the gateway of the router (the method is to click Run, enter ping -t, the IP of different routes is different, and the logo at the bottom of the route can be used) to see if the connection is normal. If it is normal, then ping the operator's DNS server IP (IP can be found in the routing management background, if you can't access the Internet at this time, it must not be ping), if the gateway can ping and the DNS server can't ping, you can test by setting a fixed IP method. Ethernet cables generally don't cause frequent disconnections, unless they're very long.

Your situation should be **. Just pay attention to whether the lower interface is plugged in tightly. Give it a try.

It is recommended to change the network card first, because it is cheaper.

I had a routing issue last time. Telecom said that the line should be normal if there is no problem, so you can only change the test in this order, and the network cable "network card" route.

This can't, if you replace it at will, it will cause the system to be unadaptable, if the model does not match, there will be a crash, a blue screen situation, if you want to change the situation to find some repair of the computer, it is best to have an acquaintance to introduce to buy.

1.The built-in wireless network card of the notebook can be replaced, but it must be found with the corresponding model.

2.The wireless network card of the laptop is a functional module, which can be replaced, and the disassembly method of the laptop of different brands and models is different, and the location of the network card may also be different, so it is best to send it to a professional for processing.

The wireless network card can be replaced, and the BIOS should be brushed before the replacement of individual machines, especially Dell has several business machines, because the notebook belongs to mobile devices, and the network access license is bound to the motherboard one-to-one, brushed into a blank BIOS, the new wireless network card can be used when plugged in, and the old wireless network card must be unlocked first. But generally don't brush, buy it back and plug it in to automatically install the driver when you boot it.

You search for the built-in wireless network card of the notebook on the **, there are quite a lot, it is not expensive, the wireless network card is generally compatible, and the wireless network card is not soldered on the motherboard, it comes with a slot, just like a memory module, you can see it when you open the back cover.

How do I replace the integrated network card on my computer if it is broken?

Go to the computer city and ask if there is a network card for sale, if there is, buy a network card and plug it into the motherboard to use. In the past, network cards were the standard configuration of newly installed computers, but later integrated network cards became popular, and they almost disappeared. If not, you can only buy a wireless network card, plus a wireless router, or change the motherboard.

It is not necessarily a problem with the network card, it may also be a problem with other aspects of the computer, and the crystal head of the network cable is also easy to break Carefully check the network cable, router and RJ45 interface, IP settings, etc., so as not to spend money in vain If you are sure that it is the reason for the network card, buy a 100 Gigabit network card with a PCI slot Shield the onboard network card in the BIOS, or uninstall the driver in "Device Manager: !

You can change it for an independent network card ** It depends on the needs of each person If the computer is more than 5 years old, it is recommended to change it Now it is very cheap to set up a computer.

You can buy a separate network card.

Plug it into the white slot under the motherboard.

More than 30 pieces.

No, the network card is the hardware that you use to access the Internet, and the ID is the address assigned to you by the network.

Of course, hardware with the same interface can be used interchangeably. But there may be compatibility issues (unusable or unrecognized. This one looks at motherboard compatibility.

Therefore, it is recommended to buy a first-line brand motherboard, and there will be more hardware for factory testing of such motherboards. This will also be much better. It's very helpless that I often see what memory incompatibility on the Internet, etc., these are not the problems of the motherboard.

Buy a cheap motherboard and put all the blame for what happened to memory... It feels like the memory is really innocent)

The main unit of the computer can be used interchangeably. The monitor can be compatible with a variety of hosts.

If it's a home network, it doesn't matter if you change the computer and the network cable, just plug it in and you can use it. Unless some companies use the network, it may be bound to the MAC address of the computer network card, that kind of can not be changed casually, if the replacement needs to contact the company's network administrator, otherwise it is easy to cause the new computer to be unable to access the Internet.

1. The network cable does not need to be changed, it is just a matter of account and password.

2. The new computer is coming, just install broadband dialing on it, and the computer seller will install it for you. If you don't necessarily ask him to install it, there's nothing else.

Yes, even the router does not need to be reset.

The graphics card can be changed at will, as long as the interface is right, it's OK But look at your motherboard, look at your CPU, it is recommended that you don't match it well, that's a waste! It is recommended that you get a graphics card like GT220 8600GT 9500GT 4670 2 hands is now the cheapest 8600GT , and in terms of performance, you can get those shrunken versions of GT220 9500GT 4670 so it is more appropriate to recommend 8600GT.

CPU is the bottleneck, change to 9500GT, no matter how good it is, the improvement is very limited.

Steps:1 Click on the network in the bottom right corner of the desktop.

2After opening the list of networks, we click [Open Network and Sharing Center] below3In the Network and Sharing Center, click [Change Adapter Settings] on the left 4 Press the ALT key to bring up the menu bar.

5. Click [Advanced] [Advanced Settings] on the menu bar

6In the advanced settings, under the option of [Adapter and Binding], click a network card, and then click the up and down arrows on the right side to change the order of the network card.

It depends on whether your network card is integrated If it is integrated, it can only be replaced by the manufacturer If it is an independent network card, then you will see if the indicator light is on after the network cable is connected If not, it may be broken Go to the same one and install it The method is to open the host cover If you don't know which one, you can look at the network cable interface If it is an independent network card, you just need to remove his screws and pull it out

If the original network card is integrated, you have to go to the BIOS to shield it. If it is independent, unplug it and insert a network card into the PCI slot.

Buy the most common 8139 network card and install it.

As long as the slot is plugged in, it can be used!

If it's an XP, you don't even need to install a driver.

As long as you go to buy a 10m 100m network card and install it, you can be hungry, and you don't need any model brand.

Just buy an 8139 one.
