priority level.
Click Network > Wireless LAN > QoS. The following screen appears.

802.11 Mode

Select 802.11b to allow only IEEE 802.11b compliant WLAN devices to associate 

with the ZyXEL Device.
Select 802.11g to allow only IEEE 802.11g compliant WLAN devices to associate 

with the ZyXEL Device.
Select 802.11b/g to allow either IEEE802.11b or IEEE802.11g compliant WLAN 

devices to associate with the ZyXEL Device. The transmission rate of your ZyXEL 

Device might be reduced. 

Super G Mode

Use this field to enable or disable the Super G function. Super G mode is available 

only if you select 802.11g or 802.11b/g in the 802.11 Mode field.
Super G provides higher data transmission rates than 802.11g. 
Select Disabled if your wireless clients do not support Super G.
Select Super G with Dynamic Turbo if some or all of your wireless clients support 

Super G with Dynamic Turbo. Dynamic Turbo uses two channels bonded together to 

achive higher transmission rates than 802.11g or Super G without Dynamic Turbo. 

Dynamic turbo is on only when all wireless devices on the network support it.  The 

wireless channel is automatically fixed at 6 if you select this mode.
Select Super G without Turbo if the wireless clients on your network support Super 

G but do not support dynamic turbo.
