THE FRITZ!POWERLINE 1240E WLAN SET
Both adapters found in the box are identical in size and measure 114mm in height, 67mm in width and 27mm in depth (each weighs 140g).
The 1240E adapter has a button and 3 activity LEDs at the front which indicate when the WLAN feature is turned on and when the device is paired with the main adapter (the button can be used to pair the device with an adapter and turn WLAN on and off).
Since the 1000E is the adapter which you will plug with your modem/router it just has the usual power and LAN LEDs (the powerline - security button/LED can be used to pair more adapters with it).
Unfortunately unlike the 546E the 1240E has but a single Gigabit Ethernet RJ45 port at its base.
A large sticker at the rear of the adapter contains its password, network key, serial number, MAC address, LED information and electrical requirements.
