Internet connection remains capped at 100mbps despite configured speed and duplex at 1gbps
Internet connection remains capped at 100mbps despite configured speed and duplex at 1gbps
I've been working through this for several days now. I copied my old drive from a PC with 100mbps NIC, but after upgrading most of my system and getting a new NIC that supports 1GBPS, my speed tests still show nothing above 1.0. I checked the Device Manager and it says the maximum speed is 100% for my new NIC, even though I enabled speed and duplex settings. If anyone knows what's happening, it would be really helpful. (Note: My connection can reach speeds up to 1GBPS.)
Your device is linked to a network that operates at 1 Gbps, such as a modem or router. Is it set up to handle that speed? For example, a Fritz!Box might have a feature called "green mode" that restricts ports to 100 Mbps. You're using a standard cable type like Cat 5, Cat 5e, or Cat6.
The cable might be faulty. Since you're using a laptop, test it by connecting it to the same device and check if the issue persists.
Verify the router has all 1 Gbps LAN ports available by testing with other devices to confirm a full GB connection. If others succeed, connect the two devices and check if your PC maintains that speed; if not, uninstall existing drivers and reinstall the latest NIC drivers, then restart your computer.
What kind of components did your previous computer use? Fast 100mbps network cards weren’t common on boards for years. If your old setup had such a card, I’d probably wipe it clean and start fresh on the new hardware just because of that. That particular Windows update seems really old, and figuring out the problem might be tough if you’re sure it’s not a hardware problem.
