this seems not to be a problem of Samsung computers only. I got an HP elitebook (supposed to be the best in their breed) and got the same issues. The common part in all of these seems to be the network chipset.
different windows versions, different brands of computers, different regions, etc
And we are only seeing the people that care enough contacting Intel and writing posts about it.
I upgraded drivers 3 times this year, tried other things like disabling miniports and so on and nothing really solved it. the people in this post are probably the more advanced PC users. Imagine the number of standard users that are not even aware.
I'm going to try to put HP to work on this but I don't expect too much...
