How to Troubleshoot Internet Connectivity Issues – Matteo

In today’s connected world, internet problems can disrupt productivity and cause frustration. This guide will help you troubleshoot common internet connectivity issues effectively.

Step 1: Verify the Basics

Check Hardware Connections
Ensure that all cables (power, Ethernet, or coaxial) are securely connected to your modem, router, and computer.
Power Cycle Devices
Restart your modem and router by unplugging them for 30 seconds and then plugging them back in. Wait for all indicator lights to stabilize before testing the connection.
Confirm ISP Status
Check with your Internet Service Provider (ISP) to ensure there are no reported outages in your area.

Step 2: Diagnose the Network

Test Wi-Fi vs. Ethernet
Connect your device directly to the router via an Ethernet cable to see if the issue is Wi-Fi-related. If the wired connection works, you may need to reposition your router or troubleshoot your Wi-Fi.
Run a Speed Test
Use a reliable speed test tool (e.g., Speedtest.net) to measure your connection speed. Compare the results with the speed promised by your ISP.
Ping the Network
On a Windows PC, open the Command Prompt and type:
```
ping www.google.com
```
This command checks if your device can reach Google’s servers. Note the latency and packet loss, if any.

Step 3: Adjust Router Settings

Reset Your Router
Reset your router to its factory settings if the problem persists. Refer to your router's manual for instructions.
Update Firmware
Visit the manufacturer’s website to download and install the latest firmware for your router.
Change Wi-Fi Channels
Interference from neighboring networks can slow down your connection. Use your router’s interface to switch to a less crowded channel.

Step 4: Advanced Troubleshooting

Check Device Settings
Ensure your device is set to automatically obtain an IP address. On Windows:
- Go to Control Panel > Network and Sharing Center > Change adapter settings.
- Right-click your network, select Properties, then highlight Internet Protocol Version 4 (TCP/IPv4) and choose Properties.
- Confirm "Obtain an IP address automatically" is selected.
Flush DNS Cache
Clear the DNS cache to resolve potential conflicts:
- On Windows, type:
```
ipconfig /flushdns
```
- On Mac, use the Terminal command:
```
sudo dscacheutil -flushcache
```

Step 5: Contact Support
