I'm trying to pick up a Ralink 802.11n USB to see what it takes to get it working. Other World Computing is doing a special on Ralink 802.11n PCI/PCMCIA/USB for $59
, so I'm considering buying one.
I'm compiling a list of Ralink 802.11n devices below, linked to the source of the info, with as much detail as I can get. Note that these are probably not supported by the rt2x00 linux driver yet!
But that support is coming soon.
Some abbreviations from the Ralink datasheet
1T3R = 1 transmitter, 3 receivers
2T3R = 2 transmitters, 3 receivers
RT2800P = PCI / Cardbus, single band (802.11b/g/n), with RT2860 + RT2820
RT2800PD = PCI / Cardbus, dual band (802.11a/b/g/n), with RT2860 + RT2850
RT2800U = USB 1.1/2.0, 802.11b/g/n, with RT2870 + RT2820
RT2800UD = USB 1.1/2.0, 802.11a/b/g/n, with RT2870 + RT2850
RT2800E = PCIe, 802.11b/g/n, with RT2890 + RT2820
RT2800ED = PCIe, 802.11/a/b/g/n, with RT2890 + RT2850
I looked for a while but didn't find any products that used the dual-band Ralink chips. Maybe some will become available in a while.
