You can manage and, if required, change your router’s settings in the Settings menu (Graphical User Interface). 
The options within your router’s Settings menu depend on the model. The basic models thus have fewer options in relation to the high-end models, which offer more possibilities for configuring settings. 
For a complete overview and explanation of the various tabs in the Settings menu, please refer to the comprehensive manual for your Sitecom router, which can be found on www.sitecom.com under Support. 

Adjusting certain settings may have negative consequences for your network. We therefore strongly advise you never to make changes without good reason. If you wish to change particular settings, please read the following tips.
