Can the bandwidth of dual network cards and dual network cables be superimposed?

Content from user: cfnjjs

Win7 dual network card Internet access.

The same computer uses a wireless network card (wifi) and a wired network card (ethernet) to access the Internet at the same time, under win7"Multiple networks"By default, only one of them is used, only one of them is disconnected from the network and the other one is immediately filled, not a broadband superposition of simultaneous Internet access; The network card needs to be the same as the number of activities or hops of the two network cards (that is, the number of the two should be the same), 20 or 40 can be the same number as long as it is the same number (the default is automatic), see the red circle in the figure below.

After the activity or hop number of the two network cards is set, the broadband can be superimposed on the dual networks at the same time, which is the effect of superimposing.

Turn on the networking of Task Manager, and it is OK if there is traffic on both networks. Now you can enjoy the dual network card speed overlay.

Yes, but if your external network egress is the same, it is useless to do so, and it can only increase the bandwidth of internal access.

This doesn't seem to stack.

Overlay is difficult, but you can make a strategy on the device by connecting to the same device (such as a router with dual WAN ports) so that some computers take different lines.

A radical solution is to replace a dual-WAN router.

1. Single network card, dual gateway Internet access windowsXP and win7 can not achieve load balancing, must rely on professional load balancing equipment or dual network ports to achieve, load balancing equipment will evenly divide the traffic into two links.

2.It is better to use the C form gateway, and the two gateways represent two links, and it is better to use different IP segments.

I only know that dual network cards can be set up to bridge, plug in two network cables, each with its own IP and gateway, whether to balance the load or not, I don't know.

You can set up static routes under WIN to use multiple network segments: set the faster ones as static routes, and the slower ones as the default routes. However, it is not possible to set up load balancing under win.

I think a lot of people set it up manually.

It's not that complicated now.

Next.. Rabbit! sub@dynamic IPA software that converts IP.

One-click IP change, especially convenient.

Dual IP effect.

This is not stackable.

At the same time, your Internet data can only go through one network exit, which is your gateway.

If, according to what you said from the landlord, two network cables and two gateways, then the data is going to **?

The equipment at home is dizzy.

Let's give a simple example.

1. Connect the two wireless network cards to the computer to install the driver, and confirm that the work is normal.

2. Dual network cards are connected to wifi at the same time.

This is a mobile Wi-Fi connection, so you need to connect separately and set it to "Auto Login" before connecting at the same time. ）

3. Check the wifi "channel".

Open cmd input".

netsh wlan sh i

4. Set the "Number of Interface Hops" (very important!) ）

Some say that it needs to be set to the same or higher, the value is not fixed, and you can modify the test yourself.

Special switches and routers (with two WAN ports) are required for load balancing, which can be overlayed.

Multi-WAN routers can achieve broadband superimposition.

Just buy one online and you're good to go.

What are the advantages of a multi-WAN router.

The router can connect to multiple external lines with multiple WAN ports, and the reasonable use of multiple broadband lines can optimize many applications and solve many problems

1. Bandwidth aggregation: Multiple WAN ports can access multiple broadbands at the same time, and the access line bandwidth can be used at the same time through the load balancing strategy to achieve the effect of bandwidth superposition. For example, WAN1 and WAN2 each access 1M ADSL broadband, when the intranet PC uses Thunderbolt FlashGet, BT and other multi-threaded tools** files, a PC can use 2 lines at the same time, so that the actual load speed reaches 2M!

2. One network with multiple lines: Multiple WAN ports can be connected to different external network lines at the same time, such as wan1 connected to Netcom and wan2 connected to telecommunications. In this way, through the built-in intelligent policy library of the router, the service accessing Netcom in the intranet takes the Netcom line, and the service accessing Telecom takes the Telecom line, which reasonably solves the problem of mutual access bottlenecks in ISPs such as domestic Netcom and Telecom, so that your network is unblocked!

3. Intelligent redundancy: When the existence of multiple WAN ports makes one of the WAN ports abnormal, the router can transfer the network traffic to other normal WAN ports in time to ensure that the abnormal line does not affect the network use, and provide a strong guarantee for network stability!

A multi-WAN broadband router can aggregate multiple broadband lines and distribute traffic evenly through dynamic load balancing, which has the effect of expanding line bandwidth and supporting the mixing of multiple lines. The above applications can be implemented intelligently!

Now there are many routers on a treasure that can be two or or more than one of the routers,Search"Multi-WAN router"You can also directly search"Ge router"You can stack the two broadbands,And the network speed is also superimposed。

I haven't tried it, I don't know if it works, I personally feel that it's not practical, and it's not very expensive to improve the network speed at Telecom.

Impossible, if the brand is different, it can't be on the Internet.

This one is more toss-up, and it is not recommended that you use it :)

Hello! Hopefully, the following will be helpful to you.

If your desktop is connected to 2 networks with 2 different devices, your network overlay will always work. However, in this access mode, because the default network routing mechanism of Windows does not allow multi-channel communication, only one channel can be used for network speed. However, when you use a multi-threaded tool such as Thunderbolt, you can achieve network speed stacking by switching networks (i.e., using a lower priority network first, and then enabling the higher priority network in the process).

If you are not a multi-NIC machine, you can use a DualWAN router to achieve network speed stacking. However, if the network is not the same ISP, you need to configure the necessary policy routing to ensure smooth access to the common network.

Anhui Telecom's online business hall took the lead in celebrating the New Year, and the red envelope for the purchase of the machine was sent immediately. Log in to receive a 30 100 yuan red envelope.
