It should have been easy!

I was seduced in my choice to test the ability of this router to either replace a defective box (unfortunately unavoidable incident).
In the box, everything you need to make the connections necessary except for ADSL filters that are placed on phone jacks.
So we find a power cable, telephone cable, a microfilm ADSL, an RJ45 cable. A records is against French by the product picture does not match the one received because of my product, there is only one antenna.
To try it, my livebox being operational, I connected this router on the box and I joined the WIFI network. The password is on the second line housing. The connection is easily made by cons I am not arrived to connect to the netgear platform that should have allowed me access to parameters and settings but my computer skills are basic ... That explains it.
I can say against that by measuring the signal quality by an application it is better to 2 to 3% compared to the Livebox.
I think if I bought this router, I would have returned because I do not feel comfortable with.
