Question: range extender
Document: ASUS 3-In-1 Wireless Router (RT-N12) is a great router to get because of the 3in1 feature because you have the router in Router/AP/Range Extender and the mode i currently use is the Range Extender for my setup which works great
I've been using it for less than 24 hours as a range extender without any problems. Easy to setup (It wouldn't detect my network with the SSID hidden though). The LEDs are blue and the strobe effect from them is a little annoying in my bedroom at night (they're going to be dimmed/blocked). Also, I thought the top was opaque, but it's semi-transparent; at night you can make out a bit of the insides.
I bought this router to use as a range extender to replace a Securifi Almond that bit the dust prematurely. So far, it's been great. Unlike the Almond, it extends my existing WIFI network rather than forcing me to create another one.Configuring it as a range extender was a bit of a PITA, but I had it done in half an hour.Only one hiccup so far, which was easily corrected. Recommended.
I ordered this product because I needed to extend the range of my ASUS RT-N56U, and may I say it does its job ALL THREE OF THEM. I pre tested all of the different functions of this router before using the Access Point mode.I am using this extender with an ASUS RT-N56U router, Motorola modem, blue ray devices, various smart phones and tablets, laptops, and finally three custom super computers used for heavy downloading.
I am using this as a wireless extender, it works great!
I would recommend this router over Belkin or Linsys. Same quality for half the price. Wide Area Range of Coverage.
Decent router, although for the price I'd have expected more. Range is so so and none of my devices will stay connected to the 5mhz band.
I updated to the latest Asus firmware and it works as expected. The range is better than the 2wire, but only just a little. It makes up for it in the speed of N.
Range is excellent in the installed environment.Ease of installation was excellent.Default installation parameters is secure.Working fine with no firmware updates.
Outstanding for the money. Works easily as well as routers in the $100 range. Easy to setup. Great range for the money. Been running for about a month with no reset needed.
Answer: We bought one to extend the range of our ASUS RT-N66U wireless router from our home office to the family room and it has really done the trick. We're extremely happy with the performance and it comes with a setup and management utility that makes everything pretty easy.
