I'm having a frustrating issue with my Ethernet connection. My PCIe Ethernet card shows a connection speed of 1000mbps in the Control Panel, but my download speeds are stuck around 100mbps. I've already tried several troubleshooting steps like disabling Energy Efficient Ethernet (EEE), forcing the connection to 1gbps, restarting the modem, and testing different cables—all to no avail. Interestingly, a friend brought over their desktop, and they achieved 1gbps just fine using the same setup. My ISP confirms they offer 1gbps speeds, but my motherboard's Ethernet port is also capped at 100mbps. I'm using a Realtek driver version 11.027.50 and have checked BIOS but didn't find anything useful. Any advice on how to resolve this?

Also, don't forget that if your cable run is too long or if there are poor connections, it can affect performance. You should also verify that your ISP service tier is indeed providing the speed you expect based on your plan.
It seems like you might be mixing up some measurements. When you say 1000gbps, are you referring to your subscription speed or the link speed of your network connection? Just remember, 1000mbps is the maximum theoretical speed, but real-world speeds can be different due to various factors.
Exactly! A 1gbps link doesn't guarantee full speeds all the time.
A lot of factors can contribute to a speed cap. The slowest speed in your network link is what you're most likely experiencing. Make sure to check the capabilities of your modem and router, as well as the quality and length of your cables; sometimes even the type of cable can make a difference if it's not rated for gigabit speeds.
I double-checked the speeds, and I'm only getting 100 mbps, not the higher MB/s, so there's definitely a disconnect.
