EDIT: OOPPPPPSS .. you live in Australia. Sorry. I'm not sure if you have these there.

Make sure it is "V2" not "V1"

Original msg:

I would suggest the Asus WL-138G V2

This card works natively in Leopard and Snow Leopard. It uses Broadcom 4318 chipset. It is detected as Third party wireless in System profile.

However, there are known issues with this card in Snow Leopard + G31M-ES2L v1.x mobo (DSDT related). If you use a different board, I think you'll be fine - but I'm not 100% sure. However, if you'll have the problem, the fix is quite easy anyway.

With regards to the actual hardware performance, it kinda sucks. If your desktop is far from the router, you might need to buy a third party rubber duck antenna to replace it. I also noticed degraded performance in Download speeds (uploads are fine).

Example: I also have a laptop (snow leo) which is connected to the same router as my Desktop.

Speedtest.net results vary:

1)Desktop (with Asus PCi card): 9.40MBps DL / 2.01 UL - sometimes DL goes lower
Laptop (with Atheros minipci-e): 13Mbps DL / 2.00 UL

2) Downloading Itunes from Apple.com
Desktop = 700mbps/sec - actual Download speed
Laptop = 1.1mbps/sec
> This has been constant all the time
> In browsing, there are no difference at all. Both are fast, just downloading.

This is constant all through out. I tried all scenarios in Windows 7,xp/Ubuntu/Leo, Snow Leo - all results are the same. If this is a driver problem, I don't know how to fix it. I've tried downloading different kind of drivers for Windows/Mac/Linux but it doesn't fix it. So I think it is not a driver problem at all.

But there is one catch. I bought this card in Ebay as USED. Now, I feel bad because right after I bought it, Newegg prices for this card got low, even cheaper than the Ebay used one. Talk about missing luck, lol. Since this is a used card, I got a feeling that the previous owner dumped this because of this problem. Or this could be a known issue for this card as well (read the newegg reviews). I can assure you though that it can connect to WEP, WPA, WPA2 encryption without any problems. You can even connect to Hidden Wireless networks without the problem with the Asus wifi. My laptop can't connect to hidden wireless.

If you're going to use it for basic internet, this card is perfect for you. I'm using it as a torrent downloader so this card is not enough for me and I'll be replacing it. Not for compatiblity, just because it doesn't fit my needs.

I'll be replacing it with a different approach (cheap alternative).

I'll be using a MiniPci to PCI adapter and buy a Broadcom Minipci chip.

= a possibly working airport card.

Mine is still on its way because it is being shipped from China, it takes 15-20 business days. And I don't know if this combo will be 100%. I know it will, but I need to test it just to make sure.

A more expensive alternative would be the MiniPCIe to PCIe adapter. With this combo, you can use a real macbook minipcie wifi. But it is way expensive. The expensive part is the MiniPcie to PCIe adapter which costs about $40. The Airport Extreme MiniPCIe usually costs $13-15.

You could buy the one from Newegg and try it. You can just return it in 30 days if you're not satisfied (you might have to pay for shipping it back though).

Good luck!
