Title says most of it - i'm looking for a 5 ghz usb wifi dongle for my Pi. I'd like it if it could run directly in the Pi without the need of a USB hub.

Does anyone know any adapters that will work? I looked at the Asus USB-N53 but can't figure out if it'll run without a hub, or if it's going to work with the Pi - can anyone help me out? :)

I always run from a Hub due to occasional outages. Anyway this may be of interest:

I will always assume you are running Raspbian for desktop and Raspbmc for XMBC !

Ok thanks :) Already looking at that site, but having a hard time finding 5ghz adapters.

The Virgin Media dongle (Netgear WNDA3200) is a dual band wifi adapter unfortunately I don't have a 5GHz wireless router to test it with but I assume it should work at 5GHz in Linux.
You'll need a rev2 Pi or a rev1 with the polyfuses bridged which is a requirement for most wifi dongles.
To get the drivers working in Raspbian and Xbian:
sudo modprobe ath9k_htc
sudo apt-get install atheros-firmware
sudo apt-get install usb_modeswitch

Thank you for that - I'm not in the states, so I can't get a Vergin Media dongle, but I might try the WNDA3100 instead, it's dual-band as well. Does yours work without a USB hub?

Also - I'm running Raspbmc if that affects anything ;)

If I recall correctly the WNDA3100 is a bad choice of wifi dongle I believe the chipset isn't compatible (broadcom??) with the Raspberry Pi or something.
I'm also a little confused by your statement "I'm not in the states" do you mean the opposite?? Virgin Media is a UK based ISP their WNDA3200 are usually bundled for free with the wireless package deal.
Many people have been selling them on eBay for as little as 8quid, not sure why though I think it's a great wifi adapter for the Pi as long as your USB ports do not have polyfuses.

But i'll have a look at ebay for it then, thanks a lot! :)

Greetings (1st post).

I would also like to know if anyone ever succeeded in getting a 5GHz dongle working with the RPi.
I saw this tutorial from someone claiming to be able to use a Virgin-branded WNDA3200 (Atheros AR7010 chipset) with Raspbian:
https://docs.google.com/document/d/1TZUCrLX5VnlHDCmrMFW7jj5hiED7FkMchHHUmzaXwfs/edit
From here:
http://www.raspberrypi.org/phpBB3/viewtopic.php?t=7351&p=90627. Has someone here ever tried this?

There's one device using the same AR7010 chip that is actually in the supported list:
http://elinux.org/RPi_VerifiedPeripherals#USB_Bluetooth_adapters.
(I think that's the only WiFi dongle that supports 5GHz in the whole list?)

I also found this USpeed Dual-Band dongle in Amazon:
http://www.amazon.com/Uspeed-Network-Wireless-N-USB-Adapter/dp/B008AE4ZE0/ref=sr_1_1?ie=UTF8&qid=1363024916&sr=8-1&keywords=uspeed+usb+wifi+adapter
There's three people in there claiming that the adapter worked "out-of-the-box" with Raspberry Pi (I assume Raspbian).


Can anyone share any experience at all with a 5GHz dongle with the RPi?
It's very important to me to get a Raspberry Pi working with a dual-band dongle, since I'm working on a project that will connect the RPi through WiFi in an environment that will be overcrowded with other devices working at 2.4GHz (bluetooth and WiFi)..

Hi There.

I just bought the TP-LINK TL-WDN3200 wifi dongle (http://www.amazon.com/gp/product/B007ZW ... UTF8&psc=1). It worked right out of the box on my B+ with no hub needed (I am running the latest version of Raspbian).

Hope this helps!

I realise it has been a while, but as this is a dual band dongle, are you sure it was running 5Ghz and not the default 2.4GHz?

I have the same TL-WDN3200 USB Wi-Fi adapter and during a quick Raspbmc setup the 5GHz did NOT work. If I chose my 5GHz SSID it would not connect, but if I chose my 2.4GHz SSID it connected fine. Also choosing "WIFI 5GHz Only" in the Raspbmc Settings program made it so that a network scan showed 0 results.
I don't know if there are drivers I can download to make it work since I am only using it temporarily until my network cable order arrives.

I'm interested in seeing if indeed 5ghz wifi works through Pi.

In the process of purchasing my first Pi. Looking to build XBMC Pi, with wifi, attached (via HDMI) to HD Home Theater Projector, both mounted to ceiling.

My "thought" is that the 5ghz will better stream online content (Amazon Prime HD, Netlix, etc. , as well local content stored on a NAS. As well freeing up 2.4ghz, while having increased bandwidth and dedicated 5ghz highway(lack of terminology).

Is 5ghz overkill?

Dual band wifi adapter I'm currently eyeing:

I use the Rosewill RNX-AC600UB (RTL8811AU) with my B+. I had to compile kernels to get it working with Raspbian, Alpine Linux and Arch Linux. I like how small this adapter is, but it does get very hot during use and there are probably better overall options (still looking).

I use this driver and it works pretty well: https://github.com/gnab/rtl8812au

I haven't tried very hard, but I have not been able to get this other one to work (using the same/similar config as the above driver): https://github.com/Braklet/rtl8811AU_rtl8821A-linux

2.4 GHz works fine while connected directly to the Pi or through a hub.

5 GHz seems to only work if the adapter is plugged into my Belkin 7-port powered USB hub. Even with max_usb_current=1, the adapter doesn't seem to get enough juice directly from the Pi.

Recently I've been running the Pi with two powered hubs connected. One hub just supports WiFi and Bluetooth adapters. The other hub supports the mouse, keyboard and an external hard drive. I don't really know, but it seemed like a better idea to not have everything passing through one USB port on the Pi.
