Connecting the extender to an existing access point
If your access point or router supports it, you can use Wi-Fi Protected Setup to connect
the range extender to the access point or router. Choose from the setup methods
below to connect the extender.
NOTE
If you have an access point or a router that does not support Wi-Fi Protected Setup,
note the wireless settings, and then manually configure the extender.

Use this method if your router or access point has a Wi-Fi Protected Setup button.
1. Press the Wi-Fi Protected Setup button on the extender.

screen (if available), OR press and hold the Wi-Fi Protected Setup button on the

3. If you used the extender’s Wi-Fi Protected Setup screen, click OK in that screen
within two minutes.

perform the WPS setup twice. The first connection will be on the 2.4 GHz band.
