isn't it too slow ?

Hello,

I have two notebooks : one with windows xp sp2 + linksys wrt54gc and the other one has Vista premium + core 2 duo so it is equipped with wifi (a/b/g/n).

I have linksys router - wrt 300n which provides internet connection for my laptops and allows them to be seen to each other.

I have noticed that the speed I can copy the files between my notebooks is as low as ~500 KB/s - 900 KB/s which I think is too slow. I regard the proper speed should be at least 3 MB/s. The signal strenght is "excellent" and the notebooks are in the same room. I use DHCP.

Please, give me a piece of advice what to do to increase this dramatically low speed.
