martin r Posted June 19, 2009 Share Posted June 19, 2009 Folks, Having trouble with PCI Wi-fi card Asus WL-138G v2 after installing nVidia video card to vanilla OS X 10.5.7. Have searched to no avail, so apologies if I've missed the obvious thread. Prior to nVidia video card install, I got high data throughput and wi-fi card recognised natively as Airport OOB. Was using mobo onboard VGA graphics. Upon adding PNY GeForce 9400 GT 512Mb and setting EFI string (to the boot.plist in my Chameleon EFI partition) I get perfect video inc. QE/GL and correct OpenGL engine BUT the wireless breaks. Noted behaviour: Airport is still recognised, and does connect sometimes, sometimes not. But even upon connection, data throughput so slow as to be almost nil. Problem is not electromagnetic interference - upon booting system with Boot-132 CD (thus skipping EFI string in Chameleon bootloader EFI partition) and using mobo onboard VGA connection the wi-fi connection is perfect again. Revert to nVidia card and it drops out again. Problem appears to be handware related as this exact behaviour has been reported on 64bit Windows too (http://forums.whirlpool.net.au/forum-replies-archive.cfm/1108285.html) I'm therefore going to replace my Asus wi-fi card (WL-138G v2 with broadcom 4318 chipset) with an alternative. However I am unsure if ALL broadcom chipset PCI cards will behave in the same way. So... Can someone with a (ideally PNY) nVidia GeForce 9400 GT 512Mb card using EFI string in a vanilla install please recommend a PCI wi-fi card they have working well and recognised as Airport to me please?
