Hi there i am looking at upgrading my laptop hardware


I hvae a hp pavillion  dv6700 series laptop

i would like to upgrade my wireless card from 802.11g to 802.11n
and my ethernet adapter from a fast 100mb ethernet adapter to a gigabit adapter?

Can i just buy any laptop adapters off trademe and put them in and will it have changed?
