@Tecnho:
Phew, how did this topic come up, but you should know that the one you recommended to me arrived and I am still very happy with it.
It was this Deiivid, although I don't know if after all this time you are still interested
TRENDnet | Products | TEW-691GR | Wireless router gigabit N450
Well, in the end I made a compulsive purchase at the MM because the Telefonica device was really annoying me, and I bought a modem-router. Now my ADSL works better with P2P downloads, and it also allows connection to a modem in case I add cable in the future, and the router's features are like those of the TRENDnet dual-band N 750, 4 gigabit ports, and a USB. The only downside is that it has internal antennas, but the truth is that the coverage it gives is very good.
I bought it basically because I found it in a store where for the rest you already know that you pay a little more than if you order it separately, and the brand is good, but they charge you extra for the Cisco label as well. But anyway, I'm happy, it works perfectly.
