There are many reasons for reducing the ability to connect your computer to the Internet. This could be due to a user or to devices on the network, even because of malicious applications or services running on the computer. So how to detect where the culprit is eating your bandwidth?
As mentioned above, there are many culprits that consume bandwidth and reduce your Internet connection. To find out these culprits, you can rely on the support of tools built into the system or software, 3rd party applications, … Below Taimienphi.vn will guide you how to find. Where is the culprit consuming your bandwidth?
What are the culprits that consume your bandwidth?
Track down the culprit of bandwidth through the Router (router)
The first and also the fastest solution to check which devices are connected on the Internet through the Router (router) is to use the DHCP Client Table. The DHCP Client Table on each Router is a bit different. For Linksys, the DHCP Client Table is in the menu Local Network in Status tab.
Next, just click the button DHCP Client Table and it will display a list of all clients currently logged on to your network. If you find a strange client, it is very likely that your neighbor is exploiting and using your bandwidth.
To end this situation, all you need to do is click Delete button located on the right of the client to delete that client. But be careful not to mistakenly delete your client. To reconnect to the network on the device, you will have to enter your security password again. Although this is not a big deal, it is just a small problem but it also takes your time.
Use third-party utilities to solve bandwidth issues
Another option is to turn to software tools to access and monitor devices on your network. Capsa Network Analyze is one of the effective software tools to access and monitor devices on your network.
Capsa is free software. On the application’s welcome window, click Start button, then access Protocol tab. Here you can see network traffic and data transfer speeds to and from other computers.
Endpoint IP tab show all servers in one interface, the bottom frame shows all remote IP connections of the server you selected at the top. This is also a way to check what your children are accessing and see what is online without having to install any tracking software on their computers.
In addition to Capsa you can also use another bandwidth monitoring application called NetworkMiner. Both Capsa and NetworkMiner work quite well, except that Capsa oversees your network activities and the different traffic protocols.
Find malware or software that is responsible for bandwidth consumption
The culprit of your bandwidth may be an application or software that runs right inside the computer without your knowledge. Old “well-known” computers have many programs running in the background, connect to some remote server and quietly send hundreds and thousands of spam messages to other email addresses. That is just an example. Malware can consume bandwidth in a variety of ways.
To find malware or software that is the culprit of bandwidth you look at all your network connections and determine if there are any abnormal connections. To do this, click the button Start =>Run to open the Run command window, then type “CMD”Into it and press Enter to open the Command Prompt window.
Enter the command “netstat -o”In the Command Prompt window and press Enter.
Above command to display all open network connections on your computer. Depending on what you open, it may take some time to display the connections on the list. Also you can append “>> network.log” at the end of the command to write to the text file.
Notice if there is an unknown HTTP or IP address in the third column and note the PID in the list. To identify applications with this strange IP address, open Task Manager (Start =>Run => type TaskMgr go to the Run command window and press Enter) and access Services tab.
Determine the PID in the list to find the problem. If it detects that any PID value has a lot of network connections and is related to a service you didn’t know was running on your computer, it’s best to stop the service and check your Internet performance. are you faster
In addition, you can view the PID values of each process running on the computer by accessing Process tab, then click View menu, select the columns and tick the box next to PID.
Find out the culprit of bandwidth use with Windows Resource Monitor
In fact, when you open Task Manager, you can access the tool that handles other bandwidth issues, by clicking Performance tab Then click the button Resource Monitor in the bottom corner.
Out of 10 Task Manager tips, many people consider Resource Monitor to be one of the most powerful tools available in a network-related troubleshooting engine.
Suppose in the example below, just looking through the value of sending / receiving bandwidth in the Network table can know the “culprit” of bandwidth consumption is Kaspersky. This could be because the antivirus software is performing a database update.
Regain bandwidth by removing malware
In addition to preventing software from stopping “blocking” bandwidth. If malware is found on your system, it is a good idea to remove it immediately, partly to reclaim bandwidth, and to protect your system. safe. When malware attacks a system, you cannot imagine how it will wreak havoc on your system’s data, files, etc.
For your part, how do you find out which culprit is eating up your bandwidth? Share your ideas, how to apply them to Taimienphi.vn.
If you are using Ondrive to back up data, you should limit the Onedrive bandwidth to limit the bandwidth consumption of this application, details how Onedrive bandwidth limit here.
