RPi USB Wi-Fi Adapters

See also: http://www.element14.com/community/docs/DOC-44703/l/raspberry-pi-wifi-adapter-testing

There is a howto on installing the TL-WN722N adapter here, which also acts as a guide for installing others too.

Working USB Wi-Fi Adapters
These adapters are known to work on the Raspberry Pi. This list is not exhaustive, other adapters may well work, but it has not yet been tried.

Note: A Wi-Fi adapter will probably need more power than the Raspberry Pi USB port can provide, especially if there is a large distance from the Wi-Fi adapter to the Wi-Fi Access Point, or it is transferring large amounts of data. Therefore, you may need to plug the Wi-Fi adapter into a powered USB hub.

Note: Some WiFi adaptors, including Ralink brand, may not work reliably unless 'wireless-power off' is included in /etc/network/interfaces. For more details see: http://www.raspberrypi.org/phpBB3/viewtopic.php?f=28&t=40474#p330868

Note: Devices with RTL8188CUS work great as wifi access point - see tutorial and configuration script.If you plan to use your raspberry pi in ad hoc mode, you must verify that your adapter is using the nl80211 driver. Wifi adaptors using RTL8188CUS driver will not work in ad hoc mode.

Note: To the owner of this page, this page would benefit of being rewritten as a matrix with - does it need external power - does it support ad hoc, ap - link to how to.

Shows up as a Ralink RT5370 device, and no drivers or additional software downloads required. Created wpa.conf, edited 'interfaces' file and restarted the networking. The manufacturer portion of the MAC address (7cdd90) is assigned to "Shenzhen Ogemray Technology Co., Ltd."
 * It works without additional software connected directly to a Rev 2 Raspberry Pi, but it stops working after a period of time (3 to 4 hours) with a fully updated Wheezy and all the 'USB workarounds' in place.

 * TL-WN723N (RTL8188SU); works OOTB with Raspbian 2012-09-17, (B) stable with 1 A PSU and without powered USB hub on r2.0. (a model B Pi with Arch Linux reboots if the dongle is plugged, restart sees the device without problems afterwards)
 * TL-WN723N v2 (USB ID: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter, FCC ID: TE7WN723NV2) Works from a box with Raspbian 2013-02-09. Used 2.1A adapter, without powered hub.
 * TL-WN725N v1. Works out of the box on Raspbian 2012-12-16 without a powered USB hub. This adapter is based on the Realtek RTL8188CUS chipset. Works great as AP - instructions and config script
 * TL-WN725N v2. Needs manual driver installation. This USB adapter is based on the Realtek RTL8188EUS chipset.
 * TL-WN727N v3 (rt2800usb, install package firmware-ralink). Works with Raspbian, supports hostapd. Does NOT require powered hub, works directly plugged into Raspberry with proper power supply (850mA, 1A worked). 40Mhz doesn't work.
 * TL-WN821N v3 (ath9k_htc, htc_7010.fw); works out of the box on ArchLinuxARM, Wheezy and on OpenElec (>r11211), Problems with prior OpenElec; needs powered USB Hub (B). This chipset is also compatible with hostapd (wireless AP software)

 * TL-WN823N Works out of box on Raspian using powered USB Hub
 * TL-WN7200ND works. Can be made as a WiFi AP using hostapd. Need a powered USB hub.
 * TL-WDN3200 See Ralink RT5572 notes.


 * Trendnet
 * TEW-648UBM USB ID: 20f4:648b, works OOTB with Adafruit Occidentials Raspbian Wheezy variant as it includes kernel with RTL8188CUS driver built-in (B)
 * TEW-649UB Works with OpenElec 3.0, chipset Realtek RTL8191SU


 * Widemac
 * RT5370 Wireless Adapter from Ebay runs without powered hub. Follow these instructions, but go to ftp.de.debian.org/debian/pool/non-free/f/firmware-nonfree/ and pick the latest firmware-ralink_0.xx_all.deb


 * ZyXEL
 * NWD2105 USB ID: 0586:341e, RT3070 chipset, rt2800usb driver (B)
 * NWD2205 USDB ID: 0586:341f RTL8192CU chipset, works out-of-the-box
 * G-202 model 0586:3410 ZyXEL Communications Corp. ZyAIR G-202 802.11bg using zd1211rw kernel module and zd1211-firmware package

Problem USB Wi-Fi Adapters
These adapters were tested and found to have issues the Raspberry Pi. Note as a possible solution/explanation for errors while running LXDE.


 * Alfa
 * AWUS036NHA (Vendor ID: 0cf3, Product ID: 9271) - Tested with Raspbian. Works fine if connected after boot. Kills boot process if previously attached. Details here.


 * D-Link
 * ( DWA-131 (rev. B1) ) - Works now on Raspbian's kernel 3.6.11+ or with DLink firmware: http://tsd.dlink.com.tw/
 * DWL-G132 - In archlinux it is recognized - lsusb: 2001:3a03 D-Link Corp. DWL-G132 (no firmware) [Atheros AR5523] - but no wlan0 device is created - perhaps it needs the firmware to be loaded


 * Edimax
 * EW-7811Un (Vendor ID: 7397, Product ID: 7811) - Reports as containing the Realtek RTL8188CUS chipset listed below, no lockup or kernel oops under Wheezy, but dmesg reports constant timeouts trying to initialize the module. This appears to be resolved on 2012-09-18-Wheezy-raspbian and newer versions. EW-7811Un causes sporadic USB Issues when used together with steelseries 6G keyboard (repeated keys, possible file system corruption)
 * EW-7811Un (Vendor ID: 7397, Product ID: 7811) - There have been issues with receiving UDP multicast packages in combination with most (not all) wireless routers. Nearly impossible to debug, since running a sniffer on the Pi makes everything work as expected.
 * EW-7811Un It doesn't support Access Point and you can't use it for hostapd.
 * Linksys
 * WUSB300N (Vendor ID: 13B1, Product ID: 0029) - Tested with Raspbian, OpenELEC, among others. No Linux chipset support for Marvell 88W8362 at all.


 * LogiLink
 * WL0085 tested under Debian (Squeeze, Wheezy, Raspbian); no stable connection can be established. This gets even worse when X is running.


 * MicroNEXT
 * MN-WD152B (Debian image) modprobe hangs when plugged in, lsusb hangs. udevd errors in the logs.
 * Possible fix: try the new Adafruit Occidentalis v0.1 image (based on Raspbian Wheezy) as it includes the needed 8192cu driver builtin to the kernel


 * Netgear
 * WNDA3100v2 tested with Debian (Wheezy); no driver for broadcom chipset (see http://www.wikidevi.com/wiki/Netgear_WNDA3100v2).


 * Pandigital 802.11g
 * Shows up in output of lsusb as: ID 0ace:1215 ZyDAS ZD1211B 802.11g
 * Kernel driver automatically loaded: zd1211rw
 * Circumstances tested:
 * Directly plugged into RasPi's USB port
 * Plugged into powered USB hub
 * Plugged into unpowered USB hub
 * Will associate with access points that do not use encryption and which use WPA-PSK.
 * Periodically deconfigures itself (layers 1-3) and become unresponsive.
 * Can be put into ad-hoc mode for an hour or two at a time but will eventually glitch out and become unresponsive.


 * Realtek
 * RTL8188CUS USB-ID 0bda:8176, kernel oops in dmesg and freeze when pulled from USB. (B)


 * Trendnet
 * TEW-424UB USB ID: 0bda:8189; tested on Debian, Fedora & Arch; rtl8187 driver; errors with LXDE running (B)


 * TP-Link
 * TL-WN821N USB ID: 0cf3:7015; tested on Debian; requires htc_7010.fw firmware; ath9k_htc driver; errors with LXDE running (B)
 * TL-WN723N USB ID: 0bda:8176; tested on Arch without a powered hub; it seems to draw too much current.
 * TL-WN723N V3 USB ID: 0bda:8179; Needs custom driver on Raspbian wheezy.
