Netgear C3700 – N600 WiFi Cable Modem Router 用户手册

If you connected wirelessly to the network and you changed the SSID, you are 
disconnected from the network.

Make sure that you can connect wirelessly to the network with its new settings. 

If you cannot connect wirelessly, check the following:

Is your computer or wireless device connected to another wireless network in your 
area? Some wireless devices automatically connect to the first open network without 
wireless security that they discover.

Is your computer or wireless device trying to connect to your network with its old 
settings (before you changed the settings)? If so, update the wireless network 
selection in your computer or wireless device to match the current settings for your 
network.

Your modem router comes with preset WPA2 or WPA security. The password that you enter to 
connect to your network is unique to your modem router and is on the modem router label. 
NETGEAR recommends that you use the preset security, but you can change them. 
NETGEAR recommends that you do not disable security.

WPA2-PSK [AES] radio button is selected so that new or old computers and wireless 
devices can connect to the WiFi network by using either WPA2 or WPA security.
