Yes, now I installed version 14.1.1.0 drivers, but speed still only 54Mbps 
So I need another wireless network card?
SAD! It should be the problem of the router.
How far is it from Notebook to router?
Did you read this...
Intel® WiFi Products — Power Save Polling (PSP) causes connection issues with some access points
Here at the settins for my My Intel WiFi 5100 AGN Connectivity Settings maybe one of the settings might help.

If you change 802.11n channel width for band 2.4 from 20MHz only to auto, does it work fine?
Though the end result is the same, different manufacturers are using different methods to have the user pick their 20/40 channels.
·Recent builds of DD-WRT have you choose the 20MHz Control channel and by specifying whether the Control channel is the "upper" or "lower" portion of the 40MHz block. You may need to toggle between upper/lower to unlock the channel you wish to use.
·Some stock firmwares have you choose a Main and Aux.
·It wouldn't surprise me if some had you also choose a main and then the center frequency of the 40Mhz channel.
Channels are specified by their center frequency but instead of displaying (center of main 20 MHz + center of additional 20MHz) the devs opted to display it as (center of main 20MHz + center of 40MHz).

Thanks PudgyOne, I've tryed these settings, but still no luck... That number (54Mbps) is driving me crazy...
The router is 1 maybe 2m from computer.
When changing channel width for band 2.4 from 20MHz only to auto, working fine.
So which setting I need choose?

channel set to either 1, 6, or 11?

WMM is required to be on for any Wi-Fi Alliance Certified N product. By default WMM is already on but many users disable it which may prevent N rates or lower throughput.
I haven't tried a DD-WRT firmware yet.
Is it your router a v1.0 or v2.0?
You could try a 4MB flash DD-WRT.
Router v2
I've got another laptop, Acer Aspire 5738ZG, he connects to my router 130Mbps!!! Without any configuration! That means the computer wireless card is bad i think I need to try reinstall Windows...
I've connected to another router with my computer. Router DIR-685. And the connection speed is 270Mbps!!! So my computer is ok...
I think the problem is my network card does not work with router linksys E1000...
How about connecting another Wi-Fi card to your router Linksys E1000, except the previous one connecting at 65Mbps.
