How do i get my 150mbs capable card on my windows 7 to perform better

[Sergie]

Hi

I have a Dell with the Intel Centrino Wireless-N 1030 capable of 150Mbps trx and 300Mbps rec. I'm only getting 150Mbps Rec 65Mbps Trx connected to a Buffalo 300N router. Windows 7. Any pointers.
Router set to N 2,4 Ghz Ch width 40Mhz.

How are you testing the speed? Are you very close to the router?

Some update. I noticed that on reset of the router or simply by making a small config change and applying or save, the link speed jumps back to 300mb (Task Manager). At exactly 5 mins later it drops to 130mbps. I've defaulted the router setting. I'm running DD-WRT v24-sp2 (08/07/10) std - build 14896 firmware on the router.

Hi yes I am within a couple of meters line of site. I'm using both task manager and the router stats to confirm link speed

How are you testing the speed? Are you very close to the router?

OK, just because you see a link speed of 300 Mbps does not mean you have a solid connection. Every so often the router and PC will renegotiate the connection speed, and if the connection has required a lot of retransmissions the speed will drop. Also, if the router has been hearing a lot of interference from another router on the same channel it will reduce the transmitter signal strength, and that will reduce the speed also.
