Even with the best network maintenance, mistakes and other undesirable things can happen. Network problems can cause your business to stop or become very difficult. The big question is: What are the most common network issues and how can you fix them?
This blog article will discuss 7 network problems that are common and how to prevent them from happening again. Let’s get into it!
1. Duplicate IP addresses
This happens when multiple devices trying to share the same IP address. This error will appear, preventing you from accessing the network.
How to fix it: The router’s default DHCP setting is the main culprit. Your subnet’s DHCP attempts to assign a new address for your new device. However, another device in your network might have occupied the address with static Ips.
To solve a network problem, you can simply disable the DHCP server if you are adding a device to your network.
2. IP Address Expiration
To detect this problem, use the ipconfig command to your PC. If your workstation has given itself an IP address beginning with 169.x.x.x it means that the DHCP server does not have any IP addresses available.
How to fix: Because most cable Internet users don’t have a local router, there may be limitations from their Internet provider. This means they have exhausted the permitted number of IP addresses.
A standalone access point or standalone router is the solution. This will give you multiple internal IP addresses, so you won’t run out of IP Addresses. You will need to adjust the address pool size if you have a router to maximize the network’s capabilities.
3. DNS Issues
DNS problems can be traced back to DNS errors such as “IP Address Could Not Be Found”, “The Network Path Was Not Found”, or “The DNS Name Does not Exist”. It is easy to check the DNS settings of a workstation by using the command “nslookup”.
How to fix: This error can be fixed by configuring your router to bypass DNS servers to your ISPs servers. If your network is busy, you will need to modify your network DHCP settings to allow direct access to your DNS servers.
4. Single PC is unable to connect to a network
Your computer may display the “No Internet” message whenever you try to open your web browser. This message may be displayed when you open your web browser.
How to fix it: You need to make sure that your network cables are checked and that Wi-Fi signals are available. Poor network drivers can cause a network to fail. It is therefore important to ensure that your workstation is configured using the current IP address, DNS servers, subset mask, and subset.
If the problem persists, you can check the firewall to ensure that all ports are open for external network traffic. This will prevent the issue from happening again. Make sure that TCP/IP is set “Automatically Assign” Most DHCP servers can create static IP mappings for devices that require a static IP address.
5. Unable to connect to a local file
Due to the number of components and devices that you need to properly set up, printing a sharing problem on a network can be one of the most difficult problems. When there is a conflict between different security environments, sharing problems are common. Even the same operating system can use different security models. This can cause interconnection problems between workstations and devices.
How to fix: Local files and sharing problems can be solved using one or more of the solutions below.
Make sure that all services are running. Servers, NetBIOS and TCP/IP must be up.
Make sure your firewall is up to date. The firewall blocks files and printers from sharing network traffic, which is a common problem. This is especially true when a new antivirus program is installed to the firewall.
Make sure all workstations are connected to the same subnet. Unexpected roadblocks can occur when internal traffic is not properly configured.
NetBIOS, TCP/IP and NetBIOS must be enabled on network adapters
To ensure access to the site is granted, you must first resolve the above issues.
Incorrect NTFS permissions
The network type is Public.
The wrong workgroup is being used in the system configuration.
Incorrectly configured Home Group.
6. Unable to connect to the Internet
It can be difficult to resolve a problem when the local network is not able to connect to the Internet. Most organizations will change Internet service providers to address the problem.
How to fix it: First, reboot your router or modem. If the problem persists, you can try the r
