10. Wireless Tests

Wireless testing fared much better than my wired testing, and ran to completion. The Chariot Condition 1 (Figure 18) throughput of 20Mbps is almost 30% higher than the top speed of the ZyAIR G-2000 that I recently tested under identical conditions, a result probably helped by the Nitro-g throughput enhancement.

Test Conditions:

- WEP encryption: DISABLED
- Tx Rate: Automatic
- Power Save: Disabled
- Mixed Mode, Nitro enabled
- Test Partner: Fujitsu Lifebook P-2000F w / Internal Broadcom wireless network card

Firmware/Driver Versions:

AP f/w: V 1.956
Wireless client driver: WinXP 3.10.39.7

Condition 2 (Figure 19) speed was also better than the ZyAIR and the Condition 3 (Figure 20) speed was about double that of the ZyAIR. Streaming performance was not as good, however, with the SMC experiencing lower UDP throughput and more lost packets.

I should note that I was unable to get a WEP connection to work with my Fujitsu Lifebook that uses an internal Broadcom-based wireless network card.
