 * TL-WN821N v4 (RLT8192CU), works out of the box on Arch, complains but works. Needs powered USB hub.
 * TL-WN823N Works out of box on Raspian using powered USB Hub, for AP follow these instructions (hostapd doesn't work out of the box). AP works without powered USB hub for me (using a 5V 2A power source for the Raspi)
 * TL-WN7200ND works. Can be made as a WiFi AP using hostapd. Need a powered USB hub.
 * TL-WDN3200 See Ralink RT5572 notes.
 * TL-WDN4200 AKA N900 - Working on hostapd on 5Gh using debian hostapd binary from apt-get with . Working a nl80211 driver. Works out of the box on Raspbian. Powered by Pi on Offical 2A power.

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. Just buy a decent USB Hub / USB cable.


 * Buffalo
 * HWU54G rev. Z2 (Vendor ID: 07b8, Product ID: 6001, listed as "AboCom Systems Inc 802.11bg") - does not work at all on a Raspberry Pi 2 running Raspbian 2015-02-16. Will not scan, will not connect.  Will work on OpenELEC 5.0.5.


 * 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.
