Wireless Features
Figure 17 shows that the Basic Wireless settings include most of what you'd want, except for the ability to adjust the transmit power level. The controls for the Atheros-based radio include a Super-G Mode, but no controls for Super-G's Adaptive Radio feature or to enable the XR (eXtended Range) feature.
I was surprised when I tried to enable Super G with Dynamic Turbo mode with the 802.11 Mode set to Mixed 802.11g and 802.11b. I got an error telling me that "Turbo mode is not allowed with 802.11b". While this is true, Super-G Dynamic Turbo is supposed to automatically drop out of Turbo, i.e. channel bonding, when non-Super-G STAs are active in the WLAN. So I think this restriction is unwarranted.

Advanced Wireless controls (Figure 18) include the pretty-standard Fragmentation and RTS Threshold tweaks as well as ability to set DTIM Interval and Beacon Period. A first for me is the 802.11d Enable checkbox, which lets the 4300 be used legally in countries that have not approved use of 802.11b / g devices.

I was glad to see that WDS is supported (bridging only - no repeating) but would have liked to see more info about it in the help and User Guide, since most users can't figure out how to set it up. Note that D-Link warns that you can't use WPA and WDS simultaneously
Tip: See our Setting up WDS Bridging / Repeating ProblemSolver if you want to know more about setting up a WDS bridge.

Rounding out our tour of the 4300's wireless features is the Wireless Security section (Figure 19). I've shown the WPA-Enterprise settings, but rest assured that WEP 64 / 128 and WPA-Personal (WPA-PSK) are also supported. Both TKIP and AES options are available in both WPA modes and the WPA-PSK key can be between 8 and 63 characters long.
