What Prevents the Realtek PCIe GBE Family Controller From Running at Full Speed?
After receiving numerous reports from multiple users, we decided to investigate the issue and devised a set of solutions that fixed it for most of our users. Also, we looked into the reasons due to which this issue is caused and listed them as follows. Now that you have an idea of the nature of the problem, we will move on towards the solutions. Make sure to implement these in the specific order in which they are provided.
Solution 1: Changing Configurations
Since the adapter needs to be configured to run at the maximum provided bandwidth, in this step, we will be changing some settings to support the maximum speed. For that:
Solution 2: Updating Software.
In this step, we will be downloading and installing the latest “Realtek PCIe GBE Family Controller” Drivers from the Realtek website in an attempt to achieve the full speed supported by the router. For that:
Solution 3: Changing Cables
One of the most major reasons due to which this issue is triggered is due to the lack of appropriate ethernet cable. In order to achieve 1.0 Gbps speeds, you need at least a “CAT 5e” rated ethernet cable. Try another cable to establish a connection between the router and the computer and check to see if it solves the issue. If the issue still persists, buy a new cable and ask specifically for a “CAT 5e” rated cable.
