Ralink Chipset Comments

Ralink makes some nice b/g chipsets, and has been very cooperative with the open-source community to release GPL drivers. Packet injection is now fully supported under Linux on PCI/CardBus RT2500 cards, and also works on USB RT2570 devices. However, these cards are very temperamental, hard to get working, and have a tendency to work for a while then stop working for no reason. Furthermore, the RT2570 driver (such as that for the chipset inside the Linksys WUSB54Gv4) is currently unusable on big endian systems, such as the PowerPC. Cards with Ralink chipsets should not be your first choice.
There is one exception with regards to the Ralink chipsets. This is the RT73 chipset. There are excellent drivers with high injection rates for the RT73 chipset. Devices with the RT73 chipsets are recommended.

ALFA-AWUS036H & ALFA-AWUS050NH INSTALLING/UPDATING DRIVERS RTL8187, r8187, RT2800usb on UBUNTU

NOTE: For surfing Internet with ALFA-AWUS050NH on Ubuntu Jaunty with rt2870sta driver, you must use the Kernel "2.6.28-11-generic #42-Ubuntu", without change or updates the drivers modules. NOTE: The tutorial is not related to Ubuntu karmic. Driver RTL8187/Stacks-mac80211 (ref. ALFA-AWUS036h) - These drivers, for surfing Internet, are more stable than r8187, and fully compatible with Network-Manager 0.7 installed by default on Ubuntu 9.04. Network-Manager 0.7 installed by default on Ubuntu 9.04. - Supports all encryption without problems. (OPEN, WEP and WPA/WPA2) - With Compat-Wireless, the "injection" working, but for support “Fragmentation attack” (opt. -5) you need to install one patch. - The RX sensitivity and packets injection is less, related to drivers r8187. Driver r8187/Stacks-ieee80211 (ref. ALFA-AWUS036h) - This driver is recommended for use with the Suite of Aircrack-ng, but not particularly suitable for Internet connections, as less stable and disc...

Packetforge-ng

The purpose of packetforge-ng is to create encrypted packets that can subsequently be used for injection. You may create various types of packets such as arp requests, UDP, ICMP and custom packets. The most common use is to create ARP requests for subsequent injection. To create an encrypted packet, you must have a PRGA (pseudo random genration algorithm) file. This is used to encrypt the packet you create. This is typically obtained from aireplay-ng chopchop or fragmentation attacks.
