I have my Acer Aspire 8951G running over a Fritz box 7490. Unfortunately, my DSL was not completely on the notebook. The bandwidth of 100 Mbit / s took the lead 3 meters already down to 54 Mbit / s while there was only a wall between them. The performance has been completely swallowed up and I was just wondering. On the terrace there were only 25 Mbit / s, the distance is about 7 meters and it's just a wall and a door in between. At first I thought the router is faulty or I but lead plates in the walls of the is not so. With Intel Dual Band Wireless AC 7260 Retrofitting I am completely satisfied. The AC supports the technology my Fritzbox 7490 I now have full power even in the garden. I can recommend it to anyone without the AC is the card swap takes less than 5 minutes and everything is going like crazy. Therefore, 5 points from me !!!
