it's definitely slow ...   but hard drive to hard drive tests (especially with a laptop) aren't that indicative of network performance.  do you have a 4200 rpm drive in the laptop?  try to find a testing program that looks at memory to memory transfers.

also, consider gigabit:  http://www.newegg.com/Product/Product.asp?Item=N82E16833328003

it's by no means the best in terms of gigabit performance, but for $10, it's hard to beat

Sorry ,it was my problem.

It was wrong gateway in tcp/ip configuration.

works perfect and quick.

1 gb file  -  around 3 min transfer,which is acceptable
