I have a new Thinkpad Edge 15 (Core i3 301DBU model). The specs say it has 10/100/1000 Ethernet. The adapter is a Realtek PCIe GBE controller (I assume that stands for Gigabit Ethernet). I connected the Ethernet to my Gigabit Router (D-Link DIR-655). But I'm only getting 100mbit speed. I looked at the driver settings. Speed & Duplex is set to Auto Negotiation but when you look at the other selections they are 1.0, 10, and 1000mps half or full duplex. THERE IS NO 1000mbps setting!
Supposedly I have the latest driver: 7.7.1002.2009 (running Win7 Pro 64-bit)
What the heck?
Solved! Go to Solution.

And to make matters worse, none of the download links work at Realtek.
I hope this isn't an error in the spec on these computers (aka false advertising) hopefully it is just that they are shipped with a driver not allowing gigabit for some reason.

Well the download link problem seemed to be a Firefox issue. I sucessfully updated to 7.34 ver driver from late last year. Still only connects at 100mbps. Man, if it turns our the specs are in error on this model I just wasted a good part of the day setting up this new Thinkpad. No gigabit is a deal breaker for me as I transfer huge files across my LAN.

Hi consultant, and welcome to the Lenovo User Community!
Thank you for coming back and posting your finding!
For 1000Mbps (Gigabit), all 8 wires of the Ethernet cable must be making good contact. 100Mbps only needs 4 wires. There are also plenty of cheap Ethernet cables in circulation which only have 4 wires and are not capable of Gigabit. Some pets and rodents are also adept at reducing the number of wires!
Glad you got it sorted!
