In my previous post I discussed my new laptop. In that post I mentioned that my only disappointment was the discovery that the wifi card, a Atheros AR9285, was a single-band card. I’ve recently replaced it with an Intel 622AN.HMWWB Mini PCI Express 6200 Centrino Advanced-N Wireless Adapter. The card is working great and the installation was about 10 minutes.
Hopefully some other Asus G73SW owner will find this information useful.
