Known Issues:
1. Using TKIP/RC4 encryption with WPA results in roughly 30% lower throughput than using WPA2 AES encryption due to a hardware limitation.
2. Turbo/superG mode does not increase traffic rate significantly for DWL-8500AP.
3. The hardware encryption for WEP is used only when a single BSSID is active on the radio. A second VAP precludes the use of hardware encryption causing low throughput.
4. Channel 14 is not supported for 802.11g band for Japan country code.
5. The APs support manual antenna selection on a per radio basis. Automatic antenna selection is not supported.
6. If the PoE cable is suddenly removed from an AP, the associated clients fail over to other APs after 6 ping losses. The roaming functionality works properly if the AP is rebooted or the radio is turned down.
7. If a captive portal instance is associated with a disabled VAP, re-enabling the VAP does not automatically enable the captive portal instance.
