Would you like to have 54g on your 11g equipped G4. Well you can now without losing a PCI Slot. D link has hidden away Drivers for the DWL G122 Wireless USB adapter on its website so that they are difficult to find. But after some ferreting around I have uncovered them. Because I had a full compliment of PCI Slots, using a card would have meant losing some functionality from my computer. The really good news is the speed of this adapter seems to blow Apples Airport Extreme off the map (I've tried the two side by side & believe me you are going to like this!).
THERE IS 1 IMPORTANT CAVEAT AND THAT IS: The adapter must have B1 on the reverse side (you can see it just before the letters F/W below). This means it is the later model & has the right chip to work with the driver!
