The configuration utility supplied on a CD does not work better. He could not find the terminal to configure.
Yet it worked fine since I was able to connect to WPS mode.
After much trial and error, I was able to access the configuration page by connecting my PC directly to the terminal with a network cable. I gave my PC address 10.100.1.2 and I acceded to the terminal with the default address 10.100.1.1
Next, the configuration has not been a big problem.
However, if you want to enable WPA2, you must exit the wireless setup WPS mode and switch to manual. You will have the option of enabling WPA2 or another, choose the name of the SSID network and also to select the band to use.
If your equipment is compatible with the 5 GHz band, you will have a more powerful connection with the 2.4 GHz band. My almost 3 years PC accepts either, but an iPhone 4, for example, do not see the 5 GHz band.
In the first case, the base station near I was connected to 210 Mbit / s. In the second case, I was limited to 130 Mbit / s, which is not so bad (802.11n WiFi card)
Conclusion: Very good product that works perfectly well, but the configuration is really difficult.
