It probably has nothing to do with the network. These netbooks are not very powerful and the limiting factor is usually processor activity. I look at the processor activity on my netbook and it is at 100% a lot of the time. Even the basic WiFi is at 54Mb/s which is faster than the speed of your internet connection which will probably not supply consistently at 50Mb/s anyway.Unfortunately you cant make a silk purse from a sow's ear.
