Assistance with Network Unmanaged Switch
Assistance with Network Unmanaged Switch
I tried port 1, which is blue and labeled 5GB. The switch doesn’t function when connected to that port. I repositioned both ends of the cable, but no other cables connect properly at port 1. There are no indicator lights or internet access. I tested multiple cables and devices, yet nothing works. A quick online search mentions a few similar reports for my BGW320-505 modem, but no definitive fix found.
A NIC functions as a Network Interface card. Back in the past, you needed a physical card for a connection; today it's built right into the motherboard. To determine the speed devices are negotiating, check the switch. On either side of each port, there’s an LED. If the left side shows solid green or blinks green, the connection is at 1 Gbps. The right side with solid yellow or blinking yellow indicates speeds between 10 Mbps and 100 Mbps. Blinking signals data transmission. This information comes directly from the TP Link manual. https://www.manua.ls/tp-link/tl-sg105/manual?p=9 For Windows 10 users, open Settings > Network & Internet > Change Adapter Options, right-click the connected adapter and select "Status" to see its speed. I don’t have AT&T, but their documentation isn’t very clear. I assume online help will show speeds for each port. You’re limited to Gigabit ports; it’s unlikely AT&T would disable lower speeds. I can’t confirm this as fact, but I’ve seen ISPs in the US make mistakes. This is why we avoid renting Comcast gear and opt for our own. Try using a Gigabit port and observe the speeds. Also, what Ethernet cable are you employing?
You addressed the issue by adjusting the Ethernet ports to 1GBps, replacing the cable twice, and contacting AT&T about a faulty port. The third Ethernet cable you used seems to have resolved the problem, allowing devices to reach full speed on the switch.
