Extender Setup and Management Interface
When first connecting to the extender, you will be greeted with the screen above. Here, you can choose to use the scan button to search out networks to connect to and extend.
If you want to do things manually, or need to change settings later on, the wireless settings are broken down into two sections. The first section is the Home Network, which is the network you want to extend, and second is the Extended Network. Above, we have the 5GHz settings, but you will find the same layout in the 2.4GHz band as well.
Here, you can change the SSID of the extended network, along with the band on which it broadcasts.
Within the advanced settings, you will find a few ways to tweak the connection on the 5GHz band. One thing I would recommend here is to enable Tx Beamforming, if you have AC devices.
The IP configuration page allows you to setup the extended networks IP range.
The wired ports on the REA20 can be configured to use the 2.4 or 5GHz networks as the incoming connection. Here, I would only go for 5GHz if your extender has a good signal to the home network.
The management settings allow you to view the traffic coming through the extender, along with upgrading firmware, or resetting the extender to defaults.
