Summary: So I got this router few years ago (about 3 1/2 years) to install DD-WRT or Tomato on it. I tried both firmwares and decided to stick with Tomato. I never ran on the stock Asus firmware, so I can't comment on it. However, I will not comment on how good the open source firmwares are, but you should give them a go. The specs of this router are very good. With 128MB of RAM, 500MHZ of CPU and a 32MB Flash, you can have a lot of stuff running on this firmware.
Pros: Tomato/DD-WRT support, Very good specs (500MHZ, 128MB RAM, 32MB Flash), All Gigabit
Summary: Overall I like this router. Easy configuration and you can set up two seperate WiFi network on this router : your own where your computers and other personal device can connect to and another you can use for your friends and others guests when they pop in and that second guest network only allow internet access. Your computers and shared data are protected if accessed by the guest network. Each has their own SSID and password.
Pros: - DD-WRT available for this router, - Realtime connection monitoring, - Good factory firmware interface, - 2x USB for storage or printer, - Main WiFi network + Guest WiFi network (each having seperate SSID and password)
Cons: - Issue tracking internet usage (latest ASUS firmware issue?)
Summary: I was happy with my old RT-N12, but was upgrading electronics with NAS box and media server, and I needed the high speed connections. Have been using the RT-N16 for 5 months, and it has been rock solid. Some have complained about range, but I was being leeched upon before I set up the security. The nearest neighbor is over 400 ft. away. I live in the country, but the signal needed to negotiate the walls of two houses and a small grove of trees.
Cons: So after my WAN port died and i went through a VERY lengthy RMA process with ASUS and received a "new" replacement it also died after only ~1 month. Same issue as before, dead WAN port. Tried everything, flashing to factory settings, using the cd recovery tool, WAN port is dead, which makes this router a paperweight. Dont even want to deal with ASUS again to get it replaced. Seriously pass on this router...there are a lot of people having issues with their WAN port dy...
Summary: Excellent router, many great features, has never dropped the signal in 3 weeks and counting. With 3 antennas I was hoping to get coverage throughout my 3500 sq. ft. house, but I still lose the signal when I get to the far areas.
Summary: I am a basic user and this wireless router works just fine. I was surprised to find that the firmware was ver 1.x out of the box and the updated firmware to a big jump to 3.x and looks much more polished. I am just using basic features so I cannot address some of the bells & whistles.
