Windows 7: Low latency and unstable speed

Low latency and unstable speed

Hello,
I'm using windows 7 x64

I made a fresh install couple of days ago, and I'm experiencing this problem ever since.

I noticed the problem while I was playing a LAN game.
The game lagged alot, and was unplayable.
When I played the game offline it worked fine.

I went to Speedtest.net and had a ping of 500+ ms,
and when the download speed was tested it wasn't consistent, the speed changed every second (+-1 MBps every second).

I made another test using my iPhone after connecting to the same network via wi-fi. the ping showed 40ms and the download speed was consistent.

My drivers are up to date,
Maybe I'm missing something, but I couldn't find similar problem on the internet.
Hope to find my help here

Thanks for your time!

p.s I tried connecting via both wi-fi and direct Cable, same results

Thank you mickey,
I did have to set a lower MTU but the problem still persist.

I think your machine is fine. You might think about updating the firmware on your router and then checking the speed again after to compare the results.

Nah, you're good, all in the green.

Problems are when you get intermittent bars in the yellow and red.

It has nothing to do with the router, because the problem happens even if I connect to other wi-fi networks.
It's somethings with the network settings, or some program that is causing it..
I just can't think of any special program that may cause this.
