ethernet speed

[jamesiha]

Hi,So I noticed that my internet speed on computer B is slower
than computer A. Both computers are separately connected
directly to Telus provided modem and router via Cat 6 cables
(both new) on Ethernet port 3 and Ethernet port 4. Logged into
Telus GUI opened up LAN STATUS showed connection speed on
Ethernet 4 is 1000 mbps and Ethernet 3 is 100 mbps. I like to
know if and how I can change the speed on Ethernet 3 to reach
1000 mbps. I hope technically advanced members here may give
me a hand on these. Please help !!

Check the PC itself. That's usually where the issue will originate, assuming the Cat6 cable isn't damaged or constructed incorrectly. Does the PC have a gigabit ethernet port on it or a 100mbps port? What kind of ethernet adapter is in your PC? You should be able to find it under ethernet properties or device manager.

 I have the Realtek PCIe GBE Family Controller on my computer. Think I have this solved by disabling Auto Disable Gigabit.

Device Manager/Network Adapter/RealtekPCIeGBEFamilyController/Properties/Advanced/Auto Disable Gigabit. 1G mbps comes up. I am happy. Many thanks for your quick reply and help. Appreciate that very much !

If you are using the same pipe for both, then one is going to be slower than the other one.
