Intel WIFI 5100 AGN draft N speed lost

Hi,
upgrading from Vista 32 to Windows 7 32, I've lost wifi speed of 300Mbps.
Notebook Vaio AW11Z/B, Router Billion 7402NX draft N, 5100 driver updated with the Intel revision for Windows 7.
The speed is about 130Mbps insted of 300Mbps, but in Vista it was working at 300Mbps.

Any suggestion on that ?

Thanks.

Hi and welcome to sevenforums

either a driver, or IPv6. if you arent using homegroup you should disable IPv6 in sharing and networking.

I had a similer issue on one of my laptops.
In Device Manager/Network adapters see whether 2.4GHz is enabled or not under the Advanced tab. If it is disabled, try enabling. As I recall, the Intel Windows 7 drivers for the 5100 in my Mini 10 default to 2.4GHz disabled. One click and speeds were back to 300 Mbps.

Super !
it was the 2.4 Ghz, it was set to "Only 20 Mhz", now I've set it to "Auto" and the speed went up at 300 Mbps again.

I have a much better access and response to all internet sites too (probably there were problems due to net conflicts generated by the above wifi setup).

Thanks for the prompt and usefull suggestion.
