I read some reviews on this product flatterers and I am surprised me. I used too dLAN 200 and I switched to AV 500 more. After ugrade firmware to version 5.2, I installed 3 plugs: my rates have more than doubled compared to the dLAN 200 I was before 60 Mb / s and 130 Mb / s (according to my access point ). I maintentant 150 Mb / s and 360 Mb / s (45 MB / s) !!! We must respect the connection tips: choose to connect your devices to the plug rather than to an adjacent outlet, because it filters out interference caused by your devices. I removed one star because I think that there is still some room to the manufacturer in enhancing firmware: the rates vary a little, but remain well above the dLAN 200 under the same conditions. As informed user, I highly recommend this product that is sure to improve in the coming months, I am sure !!!
