Three network card or USB adapter.
The oldest one is WUA1340, I got five years ago. DWA-525 just weeks ago. The LinksysAE2500 I got this week.
WUA1340 is G only. DWA-525 and AE2500 support 802.11n network. Based on the theory, DWA-525 is 3 times faster than WUA1340, AE2500 is 2 times faster than DWA525. But, the reality may be different. Let me show you the fact based on my personal test of the speed to copy a large file.
