Summary: I'm using this with a cardbus adapter in an old Dell Dimension and it works flawlessly.
Pros: No dropped signals, like some other cards I've tried. This is one of the easiest cards I have ever installed. The software worked without a hitch, just check Buffalo's site for the latest drivers.
Cons: You can only get the advertised speed, or as close as you'll get to that speed, by using a compatible Buffalo router. But it's very stable on other vendor's devices, so not really a con.
Summary: Previous card would take 10-15 minutes to reconnect when I brought my laptop out of standby. This one connects within 15 SECONDS. I'm very happy with Buffalo's products in general...I'm buying a Buffalo router next!
Pros: Works as well as the internal wireless on my wife's laptop...upgraded from an older (other brand) wireless card, and this one beats it hands down
Summary: Curiously, the BUFFALO tech support FAQ page lists the WLI-CB-G54A as compatible with Mac Powerbooks but the WLI-CB-G54S (my version) as specifically not supported. However, I installed the card, and it powered up and automatically connected to my local wireless network.
Pros: Great value as a high performance replacement for the expensive Apple Airport card on older Mac Powerbooks. Works with OS X 10.3 and 10.4 with no drivers needed (just make sure you have latest Airport update). Fast reliable connection anywhere in my house.
Summary: i have 3 different wireless pc cards, under Linux this card makes better connections then my Atheros based cards. I could have configured the others wrong but Im inclined to think it has to do with the hal from Atheros that might be nerfing those cards.
Pros: Works with Linux External antenna jack
Cons: (possible) I have heard many utils like airsnort etc dont work with bcom chipsets, i must do more research as the posts I have read/found were a little old.
