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.

Linksys AE2500

  • Wireless Dual-Band N (2.4 or 5 GHz)
  • High speed up to 300 Mbps
  • Optimized for streaming video & gaming

Dlink DWA-525
DWA 525 Front

  • Wireless N
  • 150 Mbps 2.4 GHz
  • PCI

Dlink WUA-1340


  • Wireless G
  • 54 Mbps
  • Hi-Speed USB

Testing is based on following:

Test the speed of copying a file from NAS to a PC.

  • Router: D-Link DIR-850L
  • NAS: D-Link DNS-323 Giga wired connect to router
  • PC: Located the downstairs. Windows 7 64bit. 8GB Memory


D-Link WUA 1340: 2.03MB/s


D-Link DWA-525: 3.66MB/s


Linksys AE2500:

Connect to 2.4GHz with 802.11n: 6.15MB/s

Connect 5GHz with 802.11n: 13.4MB/s


802.11n 5GHz is much faster than 2.4GHz 802.11n or 802.11g
