Answer:
The likely technical issue is misconfigured network settings or firewall blocking; troubleshoot by checking IP configuration, gateway, DNS, firewall settings, and verifying router/modem and ISP status.
Step-by-step explanation:
When a computer can reach other hosts on the local network but not the internet, it suggests that there might be an issue with the computer's connection to the internet.
Here are some common technical issues and troubleshooting steps:
Incorrect IP Configuration:
Issue: The computer may have an incorrect IP address, subnet mask, gateway, or DNS settings.
Troubleshooting: Check the network settings on the computer to ensure they are configured correctly.
Use dynamic (DHCP) or static IP addressing as per the network requirements.
Gateway Configuration:
Issue: The default gateway might be set incorrectly.
Troubleshooting: Verify that the default gateway is configured correctly. It should point to the router or gateway device that connects to the internet.
DNS Resolution:
Issue: Problems with DNS settings may prevent the computer from resolving internet domain names.
Troubleshooting: Verify DNS server settings. You can try using public DNS servers.
Firewall or Security Software:
Issue: The computer's firewall or security software may be blocking internet access.
Troubleshooting: Temporarily disable the firewall or security software to check if it is the cause. If confirmed, reconfigure the firewall to allow internet access.
Router or Modem Issues:
Issue: There may be issues with the router or modem connecting to the internet.
Troubleshooting: Restart the router or modem. Check for any error lights or indicators.
Ensure that the router has a stable connection to the internet service provider.
IP Address Conflict:
Issue: Another device on the network may have the same IP address.
Troubleshooting: Check for IP address conflicts by ensuring that each device on the network has a unique IP address.
Thus, the likely issue is misconfigured network settings or firewall blocking; troubleshoot by checking IP configuration, gateway, DNS, firewall settings, and verifying router/modem and ISP status.
