6 Problems on a Complete Computer Network With Solutions to solve it
Netgenz - Technology Computer and Internet There are various problems on the computer network that can cause local interference in the global network connection. If you fail or experience any problem then your personal productivity and even your organization will be affected. The following are common computer network problems, complete with solutions. Come see.
1. Problems in Computer Networks Due to Damage to Cables and Connectors

Cables and connectors are media that bridge between computers and other equipment. One of them serves to create a Local Area Network (LAN). Such as network cable UTP and RJ45 connectors. Network problems of this type are usually because the cable is not installed properly. Incorrect arrangement of cables and connectors, and broken cables.
Usually, network problems that use UTP cables are relatively few. This is because the installation uses a star topology and the workstations are installed in parallel using a switch/hub. So the problem that arises is usually only on the workstation cable.
The solution to this problem is to check regularly. Make sure the cables and connectors you are using are properly connected. In addition to ensuring the connection, we also recommend that you check the condition of the cable. Is the cable still good or has a defect.
2. Network Problems Due to Computer Virus
Computer viruses can come from various sources, such as malicious software, online advertisements, the use of social media on computers, and many others. This problem will attack the server system and will spread to all computers in your network. As a result, the performance on the computer network will be slow, it can even be killed by a virus.
To solve this problem, you should first check the severity of the infection by running a full network scan. Make sure your anti-virus program is up to date.
Second, back up all your system files using the necessary tools, such as an external hard disk. Third, clean or delete all suspicious files that have been isolated first. This isolation process is needed to separate them so that there is no exchange with your files or network systems.
3. Network Problem Due to System Failure
System failure can trigger problems in the computer network. This problem can be caused by a DHCP server with the same static IP address. It is possible that your internet service provider accidentally gave two people the same IP address. As a result, you will get a message in the form of “IP address already in use”.
If this is the case, you can take the following steps. First, click the “Start” button and click “Run”. Enter “cmd” into the text box and click “OK”. Then a Windows command prompt will open. Second, type “ipconfig /renew” in the command prompt and press “Enter”. Third, check your network connection. Your computer will receive an available and unused IP address.
What if you can't get an IP address? If your network is down, the operating system will send a warning stating that the device was not received from the DHCP server. This could be because DHCP ran out of addresses or maybe DHCP requests from the device never made it to the server.
The solution to this problem is to check the network interface card (NIC). Open device manager on the control panel. Expand the network adapters item area to see all network adapters. Then check the switch to see which VLAN is assigned as a member. Make sure other devices on this particular VLAN get an IP address.
4. Network Problems Due to Connection Errors and Network Connection
Connection problems are the most annoying and frustrating network problems. Problems on computer networks contained in Network Connection usually lie in the IP and gateway numbers.
These problems can be the result of all kinds of glitches and problems within the computer and/or the computer network itself. If you get a "No connectivity" notification, here's what you can do to fix it.
Step 1, restart the computer. If rebooting doesn't fix your problem, continue with step 2. Step 2, restart your router or modem. No need to reset back to default. Simply turn off the router or modem then turn it back on. If this doesn't work, continue with step 3.
Step 3, If you are connected to the network via an Ethernet cable, unplug the cable and plug it back in. If you're connecting via Wi-Fi when you see this problem, the network adapter is likely trying to save power. Then you can select uncheck the power saving option on the Wi-Fi Connection menu on the control panel. If the network is still unusable or down, contact your internet service provider for assistance.
5. Network Issues Due to Slow Connectivity
One of the problems on computer networks that are often faced is the problem of slow connections both on the network and the response of the application used. The PC can freeze and even the simplest tasks can take a long time. This problem often occurs when the computer is first turned on or connected to a network.
Many factors trigger this obstacle. Among them are heavy bandwidth usage, lack of space on the hard drive, running too many applications at once, or opening too many browser tabs at one time. The solution to this problem depends on the root of the problem.
You can identify it by using Task Manager for Windows or Activity Monitor for Mac. This is useful for seeing which apps are slowing you down. Another way that can be used is the use of certain software to increase the speed of the internet connection.

6. Computer Network Problems Due to VPN Errors
When you get a notification that says “unable to establish the VPN connection” or “error 800” it means something is wrong with your VPN. A virtual personal network (VPN) is useful in providing a secure connection between local clients and remote servers.
This issue often occurs because the client device is disconnected from the local network, the network firewall is blocking VPN traffic, or an incorrect name/address is assigned to the network. the VPN server.
Here are some steps you can take to solve this problem. First, you can check the connection between the client and the server. Second, make sure the name/address entered on the client-side matches the server name given by the VPN admin. Third, temporarily disable the firewall settings to ensure that the firewall does not block your connection.
You can try the third step when the first and second steps don't change anything. However, if you've tried the three steps above and haven't solved the problem, the server could be overloaded or offline. You can check it with the help of a technician from your IT department to solve it.
