six helpful tips to troubleshoot common business network issues.


1. Identify the Problem


Understanding the nature of the problem is the first step in troubleshooting. By gathering detailed information, you can narrow down potential causes.


Determine the Scope


First, determine the scope of the problem. Is it affecting a single user, a group of users, or the entire network? This helps you zero in on the cause, and potential solutions.

For instance, if only one user has issues, it might be a device problem. If the entire network is down, it’s likely a more significant issue.


Ask Questions


Ask users specific questions about the problem. When did it start? What were they doing when it happened? Have they tried any solutions? Gathering detailed information helps pinpoint the cause.


Check Error Messages


Look for error messages or alerts. These can provide clues about the nature of the issue. Document these messages for future reference.


2. Inspect Physical Connections


Physical connections are often overlooked. But they can be a common cause of network issues. Check cables, ports, and power sources. This can help you quickly rule out or identify simple problems.


Check Cables and Ports


Inspect all cables and ports. Ensure that cables are securely connected and undamaged. A loose or damaged cable can cause connectivity issues. Test cables with another device to confirm they work correctly.


Verify Power Sources


Ensure all networking equipment has power. Check power cables and adapters. Sometimes, a simple power issue can cause network problems. Reset power sources if necessary.


Inspect Network Devices


Examine routers, switches, and modems. Ensure they are functioning correctly, and all lights show normal operation. Restart these devices to see if it resolves the issue. Sometimes, a reboot can clear temporary glitches.


3. Test Network Connectivity


Testing network connectivity helps identify where the connection fails. As well as whether the issue is device-specific or network-wide. Using simple tools and tests can provide valuable insights into the problem.


Use Ping and Traceroute


Use ping and traceroute commands to test network connectivity. These tools help identify where the connection fails. For example, if ping works locally but not remotely, the issue might be external.


Test Different Devices


Test the network with different devices. This helps determine if the issue is device-specific or network-wide. Does one device connect successfully while another doesn’t? Then the problem might be with the device, not the network.


Check Wi-Fi Signal Strength


If using Wi-Fi, check the signal strength. Weak signals can cause connectivity issues. Move closer to the router or access point and see if the connection improves. Consider using Wi-Fi analysers to identify signal strength and interference.


4. Analyse Network Configuration


Network configuration issues can often cause connectivity problems. Check IP settings, DNS settings, and configurations on routers and switches. This can help you identify and resolve misconfigurations. Some of these are a bit technical. They might need the help of an IT services partner.


Check IP Settings


Verify IP settings on affected devices. Ensure devices have the correct IP addresses, subnet masks, and gateways. Incorrect settings can prevent devices from connecting to the network.


Review DNS Settings


Check DNS settings. Incorrect DNS settings can cause problems with accessing websites and services. Use reliable DNS servers and ensure settings are correctly configured.


Inspect Router and Switch Configurations


Review configurations on routers and switches. Ensure there are no incorrect settings or misconfigurations. Check for any changes that might have caused the issue.


5. Monitor Network Performance


Monitoring network performance helps identify ongoing issues and potential bottlenecks. There are many tools you can use for this purpose. They also help pre-warn you of network issues.


Use Network Monitoring Tools


Use network monitoring tools to track performance. These tools provide insights into network traffic, bandwidth usage, and potential issues. They help identify trends and pinpoint problem areas.


Check for Bottlenecks


Identify any network bottlenecks. High traffic or heavy usage can slow down the network. Consider upgrading bandwidth or optimising traffic flow to ease congestion.


Look for Interference


For wireless networks, look for interference sources. Other electronic devices, walls, and even microwaves can interfere with Wi-Fi signals. Use different channels or frequencies to reduce interference.


Ensure Security and Updates


Keeping your network secure and up to date is crucial for smooth operation. Regular updates and security checks can prevent many common issues.


Update Firmware and Software


Ensure all networking equipment has the latest firmware and software updates. Updates often include bug fixes and performance improvements. Regular updates help maintain a stable and secure network.

Ultimate Guide to Encryption Methods

by Tanya Wetson-Catt • 14 February 2025
Encryption is a method of securing information. It converts readable data into secret code. Only the right key can decode it. This guide will help you understand different encryption methods. What is Encryption? Encryption is like a secret language. It converts regular text into unreadable text. This unreadable text is called ciphertext. Only people who have the right key will be able to convert it into normal text, called plaintext. Why Do We Use Encryption? We use encryption to keep our information safe. It makes our data safe from hackers. This is very important for privacy and security. How does Encryption Work? Encryption uses algorithms and keys. An algorithm is a set of rules for solving problems. A key is somewhat like a password that unlocks the secret message. Symmetric vs Asymmetric Encryption There are two main types of encryption: symmetric and asymmetric. Symmetric encryption uses the same key for encryption and decryption. The same key is shared between the sender and receiver. It’s fast but less secure when the key is shared. Asymmetric encryption uses two keys: a public key and a private key. A public key can encrypt a message, while a private key can decrypt it. It’s more secure since only the private key unlocks the message. What Are Some Common Encryption Methods? There are numerous encryption methods in use today. Here are some of the most common ones: AES (Advanced Encryption Standard) AES is one of the most secure forms of encryption. It is symmetric encryption. AES can have 128, 192, or 256-bit keys. The longer the key, the harder it is to break. RSA (Rivest-Shamir-Adleman) RSA is an asymmetric encryption method. It uses two keys: a public and a private key. RSA is widely used for secure data transmission. DES (Data Encryption Standard) DES was once a popular symmetric encryption method. It uses a 56-bit key, which is now considered weak. DES has mostly been replaced by AES. ECC (Elliptic Curve Cryptography) ECC is an asymmetric technique that offers better security and more compact key sizes. It is efficient and widely adopted in various mobile gadgets. How Do We Use Encryption in Everyday Life? Encryption plays a major role in our daily life routines. Online Shopping When you purchase online, your payment information is encrypted. This protects your credit card information against hackers. Messaging Apps Apps like WhatsApp use encryption to keep your messages private. Only you and the person you are chatting with can read them. Email Security Many email services use encryption to protect your emails from being read by others. What Are the Challenges of Encryption? Encryption has many benefits, but it also faces challenges. Key Management Managing keys securely is a challenge. If some person loses their key, they probably will lose their data. Performance Issues Encryption could slow down the systems since it needs processing power for encryption and decryption. How Can You Stay Safe with Encryption? You can take some steps to securely use encryption. Use Strong Passwords Always use strong passwords for accounts and devices. That will make hacking difficult as it will take time to access. Keep Software Up-to-Date Regularly update your software to protect against security vulnerabilities in software. Use Caution with Public Wi-Fi If you need to use public Wi-Fi, avoid sensitive transactions unless you can encrypt your internet connection using a VPN. Ready to Secure Your Data? Encryption helps protect your personal information from threats. Understanding different methods can help you choose the right one for your needs.
