Reception, I installed it, and there .... socket head all evening, error during the automatic configuration after manual configuration, the default password (admin) does not work, can not go in the router. After google search in the forums, this problem is related to the browser. It is mandatory to use Internet Explorer (Chrome and Firefox is not running), big negative for me so early for this configuration.
After automatic configuration with good navigator, I finally get to go on the router. I see an administration page not very accessible, indeed, the settings are arranged in different tab and I do not find this very logical distribution, the firmware does not offer lot more options than a traditional box (difference with my Freebox => Vlan + static route), so I think it is more interesting with open source firmware. The rates are very good, I connect to 900 Mbps on the 5 GHz WiFi, copies are much faster than my Box.
