I let myself be guided when buying the reviews of other customers. The functionality of the device corresponds to the description and was also incorporate according to the instructions well in the network. I use the DIR-505 as a repeater. The DIR-505 has two LAN interfaces. However, it is indicated only one MAC address. Therefore, I had wasted some time when setting up, until I had the second MAC address found. Would have gone faster with an indication of the two MAC addresses on the packaging or the device. Conclusion: Device is good for the price and functionality. The DIR-505 is very compact. The range of the wireless increased significantly!
