Common TL-SG105 Hiccups and How to Smooth Them Out

While the TL-SG105 is known for its reliability, like any network device, users might occasionally encounter minor issues. Most of these can be quickly resolved with a bit of troubleshooting.

“Why is my speed slow?” (Cable quality, auto-negotiation)

Sometimes, users report that their connected devices aren’t achieving the expected Gigabit speeds, instead defaulting to 100 Mbps. This is often due to the quality or condition of the Ethernet cables being used.

Solution:

• Check Your Cables: Ensure all Ethernet cables connecting your router to the TL-SG105, and the TL-SG105 to your devices, are rated Cat5e or Cat6. Older Cat5 cables might not reliably support Gigabit speeds.
• Test Cables Directly: If possible, test your cables by connecting a device directly to your router. If you get Gigabit speed there, the cable is likely fine.
• Inspect Cables: Look for any kinks, cuts, or damaged connectors on your Ethernet cables. Even minor damage can degrade performance.
• Reboot: Sometimes, a simple power cycle of the TL-SG105 and the connected device can reset the auto-negotiation process.

“No Internet connection!” (Incorrect network topology)

A common mistake, especially for those new to networking, is connecting the TL-SG105 directly to the modem and then connecting both a router and other devices to the switch. As an unmanaged switch, the TL-SG105 cannot assign IP addresses or perform routing; those are functions of your router. When connected directly to a modem, the modem typically only provides one active IP address, which will be “stolen” by the first device that connects, leaving others without internet.

Solution:

• Follow the Correct Order: The fundamental rule for home networks is: Modem → Router → Switch → Client Devices. Your router should always be the device directly connected to your modem, handling all the IP addressing and routing for your network. The TL-SG105 should then be connected to a LAN port on your router to expand the number of wired connections. This ensures all your devices receive proper IP addresses and internet access.

Power LED or Link/Act LEDs not lit

If you’re not seeing any lights, it’s usually a clear sign of a connection problem.

Solution:

• Power Connection: Double-check that the power adapter is securely plugged into both the TL-SG105 and a working electrical outlet.
• Device Connection: Ensure that your Ethernet cables are firmly seated in both the switch’s ports and the ports on your connected devices. A loose connection is a frequent culprit.
• Device Status: Make sure the connected devices (computer, console, etc.) are powered on and functioning correctly.
• Cable Length: While less common for home use, Ethernet cables have a maximum effective length of about 100 meters (328 feet). Exceeding this can lead to connectivity issues.
