Wifi link 1000bgn

[Guest]

Hello,

I have dlink 2.4ghz router. I just bought thinkpad edge 14 with wifi link 1000gbn adapter on windows 7 pro. I am only getting 0.16Mb/s while I get 5mb/s or more with my another laptop with different older wireless adapter. why?
should i just return this laptop?

Is everything identical when comparing old with new -- position, channel, any new wifi neighbours ?
