The ASUS RT-N13U is a pretty good product. It fills more than one need and does so in a very easy to manage way. It is one of those products that really does make it very simple for even a novice to setup and configure. I like the icon based network map especially; it shows at a glance exactly what is and is not on your network. This beats the "system status" pages of just about any other wireless router.
The added benefit of having three full modes to play with also increases its worth in our opinion, as does the print server and NAS functions. Currently you can grab this for $54.99 from Newegg and if you can remember, you can cut another $20 off from a mail-in rebate. This is an amazing price for what you are getting.
But all is not roses with the RT-N13U; I wish ASUS would have put in Gigabit LAN ports instead of 10/100 and I also wish they would have added in the requirement of changing the admin password in the setup wizard. Still, even with these minor problems the ASUS RT-N13U is a good product and one that comes in at a good price.
