Ralink have released 10.6 driver for RT2870. Tested in 32 bit mode. OK, Should work in 64 bit also.

Both 32bit/64bit "works" for me. But drops connection to router (WRT610N) quite ofter, won't reconnect without turning radio on and off. These problems don't happen in 10.5.

I actually have the same problem with having to turn the radio off/on and remember that this also occured on 10.5.8 with Ralink drivers.

I wouldn't say they're hopeless though, better than nothing and it doesn't happen as frequently with the new driver as the old one.

I'm using a D-Link DWA140, and it works perfectly with D-Links own drivers in 10.5.8... hope they'll release one for 10.6

Yah i have the fsd8053 belkin with this chipset. Have the exact same prob in snow leo only. 10.5.8 drivers work perfect for me. 64 or 32 mode 10.6, loses connection and must restart the radio to get working.... very frustrating.. happens in like every 4 or five mins.

My new Alfa AWUS050NH is equipped with v.2 of the Ralink 2870. The CD only contained drivers for Panther, Tiger and Leo. The Leo driver is not working in Snow Leo. The current driver 2.0.0.0 Ralink offers on their website contains a package for Snow Leo, but that one only appears to be for the 2870 v.1.

Anyway, I just got my Alfa AWUS050NH with the 2870 v.2 working in Snow Leo 10.6.1 by taking the Snow Leo RT2870USBWirelessDriver.kext from Ralink's installer from their website (2.0.0.0) and adding the info.plist from the Leo RT2870USBWirelessDriver.kext from the CD for the Alfa AWUS050NH v.2. You can download the modded kext at the bottom of this posting.

Apply the kext with your favorite kext tool (in Snow Leo I use kext helper b7). You don't even necessarily have to restart; usually it is enough to just wait a minute until the kext is loaded and the diode flashes on the adapter. Then go into System Preferences/ Network and confirm the new network interface, then Apply.

I also confirm aqua-mac's Airport-like app for Ralink 2870 working with v.2 once the kext is loaded.

For those who have probs with disconnects: if you are running on WPA-PSK, try to connect via AES instead TKIP, or vice versa. I have made good experiences with flipping the encryption mode.

Please give some feedback if this driver works for your Ralink 2870 v.2 in Snow Leo.
