Question: This supports AC 5GHz but only 2.4Ghz for Wireless N? I have an Asus RT-N56U wireless N router that supports 5 Ghz. Will this pick up my 5Ghz N signal
Document: I purchased the Edimax  EW7811UTC to take advantage of the 5Ghz band from my Asus Dark Knight router, which is an awesome router by the way. Installation from the CD was easy and then updating the firmware using a download from the Edimax website was also easy. However, I was really disappointed in the performance. I used InSSIDer 3 to verify connection to the 2.4 or 5 Ghz band. 95% of the time the Edimax would connect to the 2.4Ghz band and not the 5Ghz band even though the 5Ghz band was showing to be present via InSSIDer 3.Even when it was connected to the 5Ghz band the best speed was 38Mbps download, which is not too bad.
I added an extension cable to improve signal strength to one of them as it was located in an awkward place far away from, and out of line of sight from, the router.Pros:Small sizeWorks on 5 GHz and 2.4 GHz and is able to use Wireless N or AC as desiredGreat speedReliable connectionInexpensiveCons:Easy to lose in a large bag when traveling.I highly recommend this product.
Once opened up, it was easy to find wireless networks and connect to them.Sorry for the long lead up to the good news. I happen to have two wireless routers I'm testing an AC1900 Linksys (meaning I can get 600Mbps on the 2.4GHz band and 1300Mbps on the 5GHz band), and a D-Link AC AC750 (meaning 300Mbps on 2.4 and 433Mbps on 5.0GHz). On the D-Link I was able to connect to the 2.4GHz band easily with 72Mbps connection speed - actually a darn fast connection for the kind of standard N connection, also much faster than most internet connections.
I bought this thinking it would be an upgrade to my current setup...I was wrong.. I have an Asus RT-AC66U with both the 2.4 & 5 Ghz networks setup with an HP G62 laptop running Win 7 with an i5 processor. Without the Edimax adapter I could transfer a 1gb video file to my nas at 4.5 mbps. With this adapter it was half that speed and yes, I downloaded the latest drivers from the Edimax website.
The great news, I got a really reliable solid connection to the 5GHz band at 433Mbps. That is a really fast connection, and in the neighborhood of what is possible with a wired connection.The sad news with the Linksys router, I could never connect to the 5GHz band. I got great solid reliable connections to the 2.4GHz band at 72Mbps. The 5 GHz band never showed up as available. I don't know why, or what was going on. I tried a lot of different settings on the Linksys, and could never get it to connect at the higher speed.
More flexibility for your system in a very small package!Talk to Edimax and discover where Wi-Fi is going. They already have an advance in this very small, smart looking mini USB adapter. Computer experts say it best: &#8216;In Wi-Fi wireless networking, dual band is the capability to transmit on the 5 GHz band of 802.11a and also the 2.4 GHz band used by 802.11b, 802.11g, and 802.11n. Unlike ordinary Wi-Fi equipment that only supports one signal band, dual-band gear contain two different types of wireless radios that can support connections on both 2.4 GHz and 5 GHz links.
I have a high end gaming laptop with a built in Intel Centrino Advanced Wireless-N adapter - however it has given me problems since day 1 on the 5 GHz band (strange lag spikes that would have my ping times go from 40 ms or less to over 600), drivers never helped, nothing. So I used a Edimax Nano USB wireless N adapter for some time with great success (extremely stable, excellent throughput).Well my internet speed was increased and I bought a new 802.11AC router - so I of course went looking to see if Edimax had a new Micro or Nano AC adapter and here it is.
But in practicality, it is not. Wireless AC, which operates at 5GHz band, is less capable of penetrating walls and objects than wifi operating at 2.4GHz. Despite the higher channel bandwidth, it does not provide a higher throughput with a weak signal and insensitive antenna.It is a waste of money for me.
I have a new dual band AC wireless router and a Win 7 laptop that uses the Intel Centrino Wireless N 1000 Wi Fi. It had slow Internet speed, erratic connections and dropouts even after hours trying to find and fix the problems. Decided to disable the built in Wi Fi card and go with Edimax USB adapter.Laptop is about 50 feet and 3 or four walls removed from the router and the built-in Wi-Fi had varying and poor reception on 2.4GHz, so I was apprehensive about the tiny AC 600, but tried it because it does not leave a large appendage on the laptop.
In a nut-shell, it doubles my wifi speed.Sometime back I bought a Asus RT-AC66U router as my other basic router stopped working. When I bought this Asus router my speeds went from about 25Mbps to 50 Mbps when transferring files on my LAN via wifi. Not bad without upgrading my laptop "N" internal wifi adaptor. I attributed this increase directly to the new ASUS router. It also helped speeds on other wifi connections however it was most important on my laptop.Fast forward a year. I realized I needed faster speeds than 50Mbps when transferring files from LAN computers to laptop so I finally decided to buy an AC wifi adaptor for my laptop.
Answer: I had the same question - I did find this ...The first thing to get out of the way is - like past Wi-Fi standards - 802.11ac is backwards compatible with 802.11b, g and n. This means you can buy an 802.11ac-equipped device and it will work just fine with your existing router.Read more at http://www.trustedreviews.com/opinions/802-11ac-vs-802-11n-what-s-the-difference
