I have an ASUS AC1900 router linked through a TP-Link switch to a patch panel. When connecting my PC via a wall jack to the switch, I only get 100Mbps. The entire house uses Cat 6 cabling. Checking the router's web interface shows the port to the switch is capped at 100Mbps. Is there a way to upgrade it to 1Gbps? The router itself supports up to 1Gbps, but changing speeds didn't help. I suspect the switch might be limiting the bandwidth.
Consider switching the cable or port for the router to the switch. Think about using a different port on the switch. For a home setup, I don’t think a patch panel is necessary—it adds unnecessary risk.
Ensure your router, switch, and patch panel are all set up with gigabit ethernet on the LAN ports. Inspect the connections between them for CAT5 or older cables or any internal issues with the wiring. A patch panel isn’t required for home use. Since you already have a 24-port gigabit switch, simply connect all your ethernet cables directly into it, skipping the patch panel, and link the switch to the router.
the cabling setup shows mixed connections—cat5e between router and switch, cat6 from pc to switch, and cat6 linking modem to router. The switch indicator light signals 1gigabit speeds only for the specific port your PC uses. After rearranging ports on the switch it didn’t improve performance. All patch panel cables seem intact. Could the issue lie elsewhere? I noticed my internet speed drops significantly (100-200 down, 5-10 up) even after moving in. When technicians arrived, they installed a splitter at the entry point instead of providing a new cable.
Let’s make this clearer: Your internet speed for all devices on your home network depends on the ISP connection you pay for, not just the LAN speed. Even with a gigabit Ethernet in your local area, WAN access will be limited to gigabit rates if your ISP charges accordingly. If your Asus router shows only 100Mbps to the switch, consider switching to a CAT6 cable instead of the current one. I recommend using a pre-made CAT6 cable because it offers better shielding and reliability. Make sure your cable runs under 100 meters—longer distances usually prevent gigabit performance. Also, check if you installed the cables yourself correctly; proper installation helps avoid damage, interference, or bending issues. As before, bypassing the patch panel is a good idea since it introduces more potential problems.
I wouldn't claim any work was done professionally; everything was handled by me personally. However, I made sure I could see the cables reaching into the plastic casing before crimping. If there were any damage during stripping, I’d just remove that section. The patch panel cables are ready-made. Before setting up the internet, I tested each port with a spare router I owned, and all ports connected to the switch responded successfully. I’m only able to swap the cable between the router and the wall plate that connects to the switch. I’ll add more details if needed. Yes, I understand I’m limited to the speed I pay for. Thanks for your help—it really solved the problem. The issue was the cable linking the router to the wall jack. I found an insignia cable from Best Buy a while back and replaced the one I had crimped.
I’ve learned from my own projects that small mistakes like misaligned crimps or bent cables can ruin everything. To avoid trouble, I usually opt for ready-made lengths instead of making them myself. Also, a ping check verifies connectivity, not how fast the cable is.
