Network Issue Troubleshooting

Step 1: Basic Connectivity Checks

Ensure your network cable is securely connected to your computer and the router/switch. If using Wi-Fi, verify you are connected to the correct network and have a strong signal.

Step 2: Restart Your Devices

This is often the first and most effective solution. Restart your computer, router, and modem in the following order:

1. Restart your computer.
2. Unplug your router and modem. Wait 30 seconds.
3. Plug your modem back in and wait for it to fully power on.
4. Plug your router back in and wait for it to fully power on.

Step 3: Check Your IP Address

Verify that your computer is receiving an IP address from the router. Open a command prompt (Windows) or terminal (macOS/Linux) and run the following command:

ipconfig (Windows) / ifconfig (macOS/Linux)

Look for your IP address, subnet mask, and default gateway.

Step 4: Run Network Diagnostics

Most operating systems have built-in network diagnostic tools. Use these to identify potential problems, such as DNS issues or connectivity problems.

Windows: Open the Network and Sharing Center, click "Troubleshoot".

macOS: Open System Preferences, click "Network," select your network connection, and click "Diagnostics."

Step 5: Flush DNS Cache

Sometimes, outdated DNS information can cause network problems. Flushing the DNS cache can resolve this.

Windows: Open a command prompt as administrator and run the command: ipconfig /flushdns

macOS: Open Terminal and run the command: sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
