The WDN3200 is a RT5572/5592 chipset. I believe it is that specific chipset which does not work properly in 5Ghz AP mode.
Believe or not, it is working (Barrier Braker, 1043nd).
Configuration is simple:
opkg install kmod-rt2x00-usb kmod-rt2x00-lib kmod-rt2800-usb kmod-rt2800-lib
And then edit /etc/config/wireless
config wifi-device 'radio0'
option type 'mac80211'
option macaddr 'my_routers_mac'
list ht_capab 'SHORT-GI-40'
list ht_capab 'DSSS_CCK-40'
option disabled '0'
option country 'whatever'
option hwmode '11ng'
option htmode 'HT20'
option distance '6'
option channel 'whatever'
option txpower 'whatever'
config wifi-iface
option device 'radio0'
option mode 'ap'
option ssid 'my_ap_2400m'
option encryption 'psk2'
option key 'my_secret_key1'
option network 'lan'
config wifi-device 'radio1'
option type 'mac80211'
option channel '11'
#this is in my case, may different with your configuration
option path 'platform/ehci-platform/usb1/1-1/1-1:1.0'
option htmode 'HT20'
option macaddr 'my_cards_mac'
option hwmode '11n'
option country 'whatever'
option channel 'whatever_5g'
option txpower 'whatever'
config wifi-iface
option device 'radio1'
option mode 'ap'
option ssid 'my_ap_5g'
option encryption 'psk2'
option key 'my_secret_key2'
option network 'lan'
option disabled '0'
And it is working.
There are only two problems:
1. in my case radio0 is wlan1 and radio1 is wlan0, and luci allows me to set 5g channels on the 2.4g radio and does not allow to set the 5g channels on the 5g device
2. this stick is not designed to AP, so overheating can be a (serious) problem. I'll make efficient cooling for this stick (disassemble, a little heatsink, maybe a ventillator on USB 5V)
