Card wireless adapters based on the Ralink RT2501USB and RT2601USB chipsets.
Ralink PCI Express Mini Card adapters show up as normal USB 2.0
devices and are thus handled by the The RT2501USB chipset is the second generation of 802.11a/b/g adapters from Ralink. It consists of two integrated chips, an RT2571W MAC/BBP and an RT2528 or RT5226 radio transceiver. The RT2601USB chipset consists of two integrated chips, an RT2671 MAC/BBP and an RT2527 or RT5225 radio transceiver. This chipset uses the MIMO (multiple-input multiple-output) technology with multiple antennas to extend the operating range of the adapter and to achieve higher throughput. All chips have hardware support for WEP, AES-CCM, TKIP, and Michael cryptographic operations.
HARDWARETherum driver supports USB 2.0 wireless adapters based
on the Ralink RT2501USB and RT2601USB chipsets, including:
