IT Support Services at Chicky'Oink.
Introduction.
Chicky’Oink, a busy local food establishment, contacted Installersph IT Solutions to address an urgent technical issue affecting one of their main desktop computers. The PC, which plays a vital role in processing orders, managing inventory, and accessing online resources, had abruptly lost internet connectivity. Because the business relied heavily on stable network access for efficient daily operations, the client requested immediate troubleshooting to minimize disruption. With the details provided, the IT team prepared for a standard on-site inspection focused on diagnosing and resolving the connectivity issue as quickly as possible.
Initial Assessment and Issue Background.
Upon examining the workstation, the technician confirmed that the PC had no internet connection despite being physically connected to the company network through a LAN cable. The client reported that the computer had been working normally the previous day, with no significant updates, changes, or power fluctuations that could have triggered the issue. Other devices within the establishment were still able to access the internet without interruption, indicating that the overall network was functioning correctly.
The technician began by inspecting the physical components of the setup. The LAN cable was properly connected on both ends—router and PC—and appeared to be in good condition. To eliminate the possibility of cable damage, a secondary Ethernet cable was tested. Despite this, the PC continued to show no network detection, suggesting that the problem likely originated from the computer rather than external equipment.
Troubleshooting and Diagnostic Process.
The next step involved checking the computer’s network settings and hardware indicators. Within the Network and Sharing Center, the status displayed “No network available,” and the Ethernet adapter was not registering an active connection. In the Device Manager, the LAN adapter was present but occasionally showed warning icons. The technician attempted to reinstall and update the network drivers, ran system diagnostics, and performed a TCP/IP stack reset. None of these actions restored connectivity, indicating that the issue was not driver-related.
To further isolate the hardware, the technician conducted a targeted test using an external USB-to-Ethernet adapter. Once plugged in and configured, the computer immediately detected the network and gained internet access without issues. This successful connection verified that the system software was functioning correctly and that the router was not at fault. It provided strong evidence that the built-in LAN port on the PC’s motherboard was defective or failing.
Final Assessment and Recommended Solution.
After completing the diagnostics, the technician concluded that the PC’s onboard LAN port had likely sustained internal hardware damage. The client was informed that the most practical solutions were either to use a USB-to-Ethernet adapter as a long-term workaround or install a dedicated PCIe network interface card for a more permanent hardware repair. Both options were explained, including their reliability, installation requirements, and cost considerations.
Chicky’Oink opted to continue using the USB-to-Ethernet adapter, as it immediately restored full network connectivity and allowed the business to resume operations without delay.
