ASUS Wireless Router RT-N56U

I got the router more than half an year ago, to replace my old D-Link DIR-655 which was really good router but had ridiculously weak signal (I had problems to connect my mobile devices in the other rooms. Later, I also found that the weak signal was the reason for my wireless printer to malfunction).
As usual, I am not going to write a complete review but only to add my personal opinion and experience that is not mentioned anywhere else on the net.

To begin with, the router is really good, fast and with plenty of features out of the box. I have to mention that the official web page was well behind the real specifications of the actual firmware at the time I bought it. I was very close to buy the better and more expensive router RT-N66U just because it said that it has VPN. For my surprise, when I upgraded the router to the latest firmware, right after I bought it, it had already VPN...

Just to mention my priority pros/cons features that are specific to this router (I assume that port-forwarding, virtual host, etc. as standard): Firmware version: 3.0.0.4.374_979 at the time of the review.

Pros:

• Fast dual-band 2.4GHz/5GHz wireless router
• Gigabit WAN/LAN
• Strong signal
• Support for 3G/4G modems (a bit limited but still quite functional)
• Multi-Function Twin USB 2.0 Port + samba share
• Advanced web interface
• telnet - this is really perfect!
• Traffic manager
• Network tools: ping, traceroute, nslookup, netstat, Wake On Lan
• System log
