Hey, I've recently bought a mac mini (newest revision) and I noticed that it's wireless card is a lot better at retaining high speeds (especially at 5ghz spectrum). Is there a pci-e wireless card that I could pop into the MP that's better?
You can get the compatible Atheros or Broadcom models, but they'll just have the same problem.
I've read many people state their reception and throughput increased a great deal by going outside the metal case with a USB wi-fi stick. A PCI card with external antennas would probably do the trick too.
