The Gotcha in Draft 11n Wi-Fi Certification

  • My previous post describing the D-Link DIR-655 / DWA-652's failure to switch from 40 MHz to 20 MHz channel mode when encountering a legacy WLAN, might be counter to what D-Link says is the expected behavior. But I have found that it is neither a violation of IEEE Draft 2.0 nor the Alliance's Draft 2.0 11n Certification.

    Since that post, I've exchanged emails with D-Link and spoken with both Atheros and the Wi-Fi Alliance to try to find out how the D-Link products could not be performing as D-Link had described, yet receive Wi-Fi Draft 2.0 11n Certification.
