X220 thinkpad laptop: Slow internet speed - wifi card?

I've got brand new X220 with i5, and 6-cell battery. The problem is that the internett speed is ok the first 10-15 min,  but after 10-20 min download speed seems unstable and slow. Does load constant if i stream or go to a page. 

 

I have tried several method in order to fix my internet problem. Without luck I have tried:

Updating the driver, updating the BIOS, tried to change channel in modem, i tried to set AUTO under wireless settings, i have tried to have the charger in and whitout, I have tried with wireless-usb-card,

 

One interesting fact, when i sit very close to the modem, the speed becomes good and stable. The speed is also good on different network.  Also with Cabel it seemed good. What can be the problem, and how can i  solve it?

 

i have wireless card Wifi Link 1000 BGN 802.11n with channel for brand 2.4.

Download inSSIDer and see if there's a neighbouring network that's overpowering your own.

I did, two of my neigbour have same channel. I changed to other channel, still slow. But one fact i just found out that when i put choose powerplan: Maximum power. The speed increases. But still not fully fast. And i also checked if i had latest modem/router update, which i have.  Still not found out a working solution.
