I’ve been struggling with my ailing MacBook for awhile now. It’s had a bit of a hard 4 years: bad palm-rests, bad fans, poor battery life, bad CD drive. The most recent is bad WiFi signal strength. It could be a bad Airport card, or just a bad antenna, but either way I can’t get a connection more than 20 feet from the router. I could try replacing the card and antenna, but that would end up being about $80 and a couple more cracks in the computer’s shell.
Instead, I went for the 802.11N1 1T1R from MonoPrice. It set me back a total of about $11, and was billed as being OS X compatible, which is only partly true. It is compatible, but they don’t give you the drivers. The card uses the RTL8188SU chipset from Realtek, and unfortunately, in my mind, Realtek has become known for cheap components without the drivers you need. Fortunately, there is usually a company using the chips that is also willing to provide some sort of support for them. In this case it’s Airlink101. They uses their own part numbers, but it looks like the AWLL5077 uses something similar to the RTL8188SU. I’m not sure how long this link will work, but the main idea is the model number. Based on some posts on the Ubuntu Forums, but it may also apply to the 8712/8191/8192 chips, but don’t quote me on that.
On another note, we have the issue of using Airlink101′s resources. Of course, if something breaks, then it’s my/your problem not theirs, but in the grand scheme of things, they are really helping to solve the problem of driver support on Mac’s. To be honest, I would not buy this card again, the driver issue is annoying, but the card is actually quite fat and blocks my second USB port. If you need a WiFi card for your Mac, look into Airlinks101′s products. I can’t guarantee they will work, but you can get a much smaller card with the same chip and save a bit of space and trouble.
