Hi, Long time lurker, first time poster. Thank you in advance for whatever help you can give. I look forward to reciprocating. I have just inherited an old PowerBook G4, running OS 10.4.11. It's 802.11b only. No good, so I picked up an Addlogix dual-band 802.11a/b/g/n USB adapter, model MA-WL-USB-N300. I can't seem to find a driver, either on the CD or the web, that will work with 10.4. 10.5 looks promising at Ralink's site (guessing as to which Ralink chip is inside), but I was told by the retailer that OS 10.4 onwards already included the necessary drivers. The device does show up in the System Profiler when I plug it in, but I can't get it to do anything. Addlogix's tech support link is broken--surely not a bad sign?? A commenter at another major retailer who carries this item says, "plug&play for my apple ibook powerpc g3! mac os x 10.4.11 didn't need the software; I just plugged in the stick. set the wireless utility in the system prefs & it works like a charm!" Super. I just must not know where to click. Can someone help me? Now if we have to get really geeky here, here's my idea: I want to see the details as to what driver, if any, is being associated with that device when I plug it in. This is surely possible in *nix, so could someone (familiar with the Terminal, perhaps) tell me what to do on that front? It would be a good thing to know in general, anyway.
