Introduction
The TG789vac v2 constantly monitors all the user activity via the TG789vac v2 and uses this information to optimise its
power consumption:
For example:
•The TG789vacv2 is able to reduce the clock frequency of its central processor when there is no or low user activity. This
lowered clock frequency will result in a lower power consumption of the TG789vac v2.
• Disable the USB port(s) when they are not used
• Reduce its Ethernet switch functionality to link detection when there are no devices connected to the Ethernet port.
• Switch its wireless interface to power reduction mode.
Wireless access point power reduction mode
When the TG789vac v2 access point switches to power reduction mode, the access point is switched off and is only switched
on periodically to allow to detect new wireless clients. If new clients are detected the wireless access point is immediately fully
powered again.
Power reduction is enabled by default, but it is possible to disable it via the TG789vac v2 GUI. To configure power reduction:
1 Browse to the TG789vac v2 GUI.
For more information, see “Accessing the TG789vac v2 GUI” on page 29.
2 On the left menu, click Home Network.
3 The Home Network page appears, Under Wireless. click:
WLAN to view the settings of the 2.4 GHz access point.
WLAN_5G to view the settings of the 5 GHz access point.
4 In the Navigation bar, click Configure.
5 Under Configuration:
Select Power Reduction Enabled to enable power reduction.
Clear Power Reduction Enabled to disable power reduction.
6 Click Apply.
The TG789vac v2 will only switch off the access point if there are no devices connected to the access point at that
moment.
