Hey I have just bought two samsung 700z3a. Before i read several tests that confirm that this is a good one. And its a nice laptop. There is only one problem.. The wi fi signal is terrible low on my new laptops.. Before i had dell latitude e6400, it always hadd "full" wi fi signal at home, but the samsung i terrible low.. What can i do about this?? The wireless router is same as always d-link dir 655.
