If your PC is only getting 100 Mbps, check your Ethernet cable; it should be Cat 5e or higher. Ensure your network adapter supports gigabit speeds and update its drivers. Also, confirm your router's gigabit ports are in use. Network settings and ISP plans might also restrict speeds.
FAQs & Answers
- Why is my PC limited to 100 Mbps internet speed? Your PC might be limited by using an older Ethernet cable below Cat 5e, a network adapter that does not support gigabit speeds, outdated drivers, or router ports that aren’t gigabit capable.
- How can I check if my Ethernet cable supports gigabit speeds? Look for cables labeled Cat 5e or higher (such as Cat 6 or Cat 6a); these support gigabit speeds, unlike older Cat 5 cables.
- Does my router affect my PC's internet speed? Yes, if your router’s connected port does not support gigabit Ethernet or if firmware is outdated, it can restrict your PC speed to 100 Mbps.
- Can ISP plans limit my internet speed to 100 Mbps? Yes, if your internet service plan offers maximum speeds of 100 Mbps or less, your connection speed will be capped regardless of your hardware.
