Hello everyone,
I was searching for a pci wifi card that works on the 5ghz band and works on OSX of course. So I found the Linksys WMP600N dualband pci wifi card with a RALINK2860 chipset that's supposed to work on osx. (with these drivers Drivers RALINK2860 ).
The installation is quite straightforward:
1) Install the drivers.
2) Reboot.
3) I checked if the RT2860WirelessDriver.kext was in my extensions folder.
4) Shut down again.
5) Connected the wifi card and booted up.
When I booted into osx, the Ralink wireless utility already started up and found my router right away.
I wanted to use the 5ghz band because the 2.4 band in my neighbourhood is quite saturated (25+ routers) and I couldn't use my o so sweet 60mbit internet connection to the fullest. So I switched to 5ghz on my linksys 610n router, and had no problems getting 60mbit out of the connection.
I'm a happy man, that just wanted to let you guys know that the linksys wmp600n works quite well under osx 10.5.6
Cheers,
Petrov Young
