Setup is simple for universal repeater, we must think about resuming the safety of ADSL box, encryption, etc. Is seen on the network after, easy to administer.
In client mode AC is frankly painful in DHCP (IP adress to a fixed preferably to the connected device), and difficult for the configuration called "Enable WDS" that is trapping, it operates or planting.
Another suggestion: Well think about putting the same subnet as the box. For example 192.168.1.254 and printer at 192.168.1.11 for a box in 192.168.1.1. Do not put the client or printer in another subnet (192.168.0.x for example).
In times when all tested and configured, the range is excellent, and this device works fine, but you can quickly spend a few hours in various configurations and tests.
Other small flaws:
1. No integrated diagnostics to determine the signal strength between the repeater and the box, it's a shame, this feature might have been easy to add to the management interface. It is therefore necessary to grope for the optimal positioning of the repeater.
2. The plant reboot sometimes prefer by far the old manual method disconnect and reconnect the power supply to the reboot.
