Airport cards are nothing more than rebranded WaveLAN Gold cards. Same speed, same everything. WaveLAN Silver cards are hardware-wise the same, but firmware limited to WEP 64-bit encryption only. They can be turned into WaveLAN Gold cards through a firmware upgrade in an Airport Slot on a Mac. I'm not sure what exactly a WaveLAN Turbo is, but I'd image is still a WiFi B card. Any Airport compaitable card that will fit into that slot, will be a B only card. Lucent got bought out/was sold to Alcatel. The two cards should be the same.
For best results, it's best to get an Airport card. They don't have the extra integrated antenna sticking out of the end of them and they always have the port for the Mac's built in antenna.
yes true but if i stick to the APC inernally then il have incredibly slow as a snail internet (ive used Wireless B in the past) id rather use my Linksys WMP54G PCI card as its faster speed and is said to work if it dont i got a USB Wireless N Card from ZyXel that will work
