Computer link speed shows 100Mbps limit, should be capable of 1000Mbps.

I recently moved to a new house and got a new 200Mbps download and 20Mbps upload bandwidth connection through my ISP. However, I was downloading something on my computer at ~12MB/s, and the Task Manager showed my Network load was at a full 100%. When I checked the details it said the Link Speed of my computer is 100Mbps.

I checked the following things:
- I have a Technicolor TC7200 modem, which supports Gigabit speeds.
- I have a direct CAT-5E cable from the modem to my computer.
- My computer's network card supports Gigabit speeds, and the Speed is set to 1.0Gbps. (Qualcomm Atheros AR8161 PCI-E Gigabit Ethernet Controller (NDIS 6.30))
- The drivers of the network card are up to date, or that's what it said when I used the automatic search options.
- I borrowed a laptop and attached it to the Ethernet cable, and there the Link Speed was shown as 1.0Gbps, and I could realise download speeds of over 20MB/s just fine.

Now I am paying for 200Mbps bandwidth but my main computer caps out at 100Mbps, does anyone have an idea on how to solve this?

Thanks!

The Task Manager always goes by the adapter Set Speed, so this indicates, despite of what you have said, for 100 mbit only. I always recommend using the LAN driver from the mobo's vendor and not from Microsoft. Other than that try hard configuring both ends to 1 gbit, rather than let it auto-negotiate.

Have u recently updated to W10?

Hi, thanks for your response.

- My adapter speed is set to 1.0Gbps, so therefore the task manager should always show 1.0Gbps as well? (see picture)
- I downloaded the LAN driver from the motherboard company but it did not fix anything.
- My computer end is already hard configured to 1.0Gbps (see picture), and in my router settings I don't see any options regarding connection speed.

I am on Windows 8.1 and did not update in the recent past. I took a screenshot of how I set the adapter: http://i.imgur.com/gwYDnPQ.png

Any other ideas?

I too am having this problem. I have always had a 1gbps connection, and all of a sudden its capped at 10mbps. I change speed/duplex to be 1gbps, and it doesn't change anything, still capped at 10mbps
