The news:
1) Finally an ON / OFF button area (it avoids physically unplug to turn it off).
2) WLAN ON / OFF button which lets you stop the broadcast WiFi without using the software interface. If it works!
3) A push button 'N' Connect using WPS (interesting for users of WPS-compatible devices).
The "Smart Wizard" (software interface) research and now installs automatically firmware updates.
What has been lost:
1) The ability to transmit logs (or logs) to an email address. A pity, especially as the logs provided is more comprehensive than the old :-(
2) The antenna is fixed now, not possible to connect a more powerful external antenna.
Nevertheless, it seems that WiFi signal provided by the integrated antenna is more powerful than the older models (V1 to V4).
The installation? Always as simple: the attack with Safari or Firefox by [...] is told ADSL account identifier of the ISP + PASSWORD.
We wait a moment and the connection is made, all the parameters displayed in "Router Status" :-)
I take it one star because of the impossibility of transmitting the logs.
