Not bad but could do better 14 1

I just got 2 packs duo Bewan S200maxx and given rave reviews of the site I was told that it was easy to install and it does not take me more than a few minutes.
No problem with one pack duo. Indeed the install is super fast.
But with 2 packs or 4 adapters bcp it took me longer. Indeed, it is very easy to pair the two adapters supplied in the same duo is apparently more complicated to do it with two adapters from two different duets.
For those who encounter the same problem, I can say what I did: after as diverse and varied trial and error, I have paired 2 adapters of different duos by installing the utility Bewan Powerline E200 provided on one of my PC, pair before, in the Security tab of the utility I have chosen the action "random NMK." Do not ask me why because I conducted as a bit of desperation. Luckily the third pairing went well. There was a big drag on the fourth that I overcame the last by connecting adapter on the PC where the utility was installed (an aside here to say that it is better to have a XP for this seven maneuver, I spun a little bit of "random NMK" and I then paired and there miracle 4 adapters were talking together. All that to say that instead of 10 'that I intended to spend on this case it m' took bcp, bcp more!
The positive point of this purchase is that these duets are better market competition and work very well after the successful pairings.
