The RT2500 chipset is the first generation of 802.11b/g adapters from Ralink. It consists of two integrated chips, an RT2560 MAC/BBP and an RT2525 radio transceiver.

The RT2501 chipset is the second generation of 802.11a/b/g adapters from Ralink. It consists of two integrated chips, an RT2561 MAC/BBP and an RT2527 radio transceiver. This chipset provides support for the IEEE 802.11e standard with multiple hardware transmission queues and allows scatter/gather for efficient DMA operations.

The RT2600 chipset consists of two integrated chips, an RT2661 MAC/BBP and an RT2529 radio transceiver. This chipset uses the MIMO (multiple-input multiple-output) technology with multiple radio transceivers to extend the operating range of the adapter and to achieve higher throughput. However, the RT2600 chipset does not support any of the 802.11n features.

The RT2700 chipset is a low-cost version of the RT2800 chipset. It supports a single transmit path and two receiver paths (1T2R). It consists of two integrated chips, an RT2760 or RT2790 (PCIe) MAC/BBP and an RT2720 (2.4GHz) or RT2750 (2.4GHz/5GHz) radio transceiver.

The RT2800 chipset is the first generation of 802.11n adapters from Ralink. It consists of two integrated chips, an RT2860 or RT2890 (PCIe) MAC/BBP and an RT2820 (2.4GHz) or RT2850 (2.4GHz/5GHz) radio transceiver. The RT2800 chipset supports two transmit paths and up to three receiver paths (2T2R/2T3R). It can achieve speeds up to 144Mbps (20MHz bandwidth) and 300Mbps (40MHz bandwidth.)

The RT3090 chipset is the first generation of single-chip 802.11n adapters from Ralink.

The RT3900E chipset is a single-chip 802.11n adapter from Ralink. The MAC/Baseband Processor can be an RT3290, RT5390 or RT5392. Download ez.photo.calendar.creator.plus.v907.rar. The RT3290 is a combo 802.11n and Bluetooth chip. It operates in the 2 Ghz spectrum and supports one transmit path and on one receiver path (1T1R). The RT5390 chip operates in the 2GHz spectrum and supports one transmit path and one receiver path (1T1R). The RT5392 chip operates in the 2GHz spectrum and supports up to two transmit paths and two receiver paths (2T2R).

These are the modes the ral driver can operate in:

BSS mode

Also known as infrastructure mode, this is used when associating with an access point, through which all traffic passes. This mode is the default.

IBSS mode

Also known as IEEE ad-hoc mode or peer-to-peer mode. This is the standardized method of operating without an access point. Stations associate with a service set. However, actual connections between stations are peer-to-peer.

Host AP

In this mode the driver acts as an access point (base station) for other cards.

monitor mode

In this mode the driver is able to receive packets without associating with an access point. This disables the internal receive filter and enables the card to capture packets from networks which it wouldn't normally have access to, or to scan for access points.

The ral driver can be configured to use Wired Equivalent Privacy (WEP) or Wi-Fi Protected Access (WPA1 and WPA2). WPA2 is the current encryption standard for wireless networks. It is strongly recommended that neither WEP nor WPA1 are used as the sole mechanism to secure wireless communication, due to serious weaknesses. WPA1 is disabled by default and may be enabled using the option 'wpaprotoswpa1,wpa2'. For standard WPA networks which use pre-shared keys (PSK), keys are configured using the 'wpakey' option. WPA-Enterprise networks require use of the wpa_supplicant package.

The ral driver relies on the software 802.11 stack for both encryption and decryption of data frames on the RT2500, RT2501 and RT2600 chipsets. On the RT2700 and RT2800 chipsets, the ral driver offloads both encryption and decryption of data frames to the hardware for the WEP40, WEP104, TKIP(+MIC) and CCMP ciphers.

The transmit speed is user-selectable or can be adapted automatically by the driver depending on the number of hardware transmission retries.

In Host AP mode, devices with the RT2700, RT2800, RT3090, and RT3900E chipsets are compatible with clients using powersave.

The ral driver can be configured at runtime with ifconfig(8) or on boot with hostname.if(5).
