Only 100 Mbps on a 1Gbps network connection and Task manager shows 100% NW

[Guest]

I have a 1 Gbit per second connection, but every time I download something of the internet (for example Steam games), it will only allow 100 Mbits per second and everytime the speed reaches 100 Mbps the network graph in Task manager shows 100% receive connection limit and the PCs starts to lag and becomes really slow. But when my friend tries to download something of the internet on his PC via the same cable. He gets up to 800 Mbps. I have installed the newest Ethernet driver (Realtek LAN Driver for Microsoft Windows 8 (32-bit, 64-bit)).

My PC is Lenovo Ideapad u410 (i7, 8GB RAM)

According to the specs of your laptop, the Ethernet adapter only supports 10 Mbps and 100 Mbps. There's nothing that can be done without changing the adapter.

Your friend's PC supports 1 Gbps Ethernet, apparently.

From the specs page:
http://shop.lenovo.com/us/en/laptops/ideapad/u-series/u410#techspecs

"Wireless Connectivity 10/100 LAN"

100 is all you will get with that.

USB 2 is 480 Mbit/s So look into a usb lan cards.

USB port to a 10/100/1000 Base-T Ethernet port

And what does it take this changing of the adapter?

Ridiculous that a new notebook costing around £700 only has 10/100 lan.

niklamacz: The Ethernet adapter on your laptop is probably built into the motherboard, so it cannot be changed out for a replacement. However, you can use a USB adapter, like allennnn suggested above, or possibly an Expresscard/PC Card if your laptop has a slot for it.

To allennnn: I know! If the 6-year old Dell I am currently typing on has a 10/100/1000 Mbps Ethernet port on it, why can't newer ones? Seems like it is only the business-class laptops that have Gigabit Ethernet.
