Since I was tired of the arguments I've decided me to take it all yourself in the hand and overturn the wireless router from the ISP. To avoid future problems, I have to buy a higher quality product and decisiveness have been made on recommendation to the Buffalo - quite rightly.
I would recommend this product - this includes the various firmware types all work great and are easy to configure and simple to use - only the menu could be a bit clearer ... but in which the router is already the case?
The only drawback: The drive large advertised USB hard drive to the router and use it as "NAS" works for me, unfortunately, not at all ...
Those who do not but focuses on can buy the device or its big brother with no worries.
