Can I connect this device directly to the output of my cable modem via RJ-45 or must I have an already installed wireless adapter?

Accepted Answer

No, the wired ports do not work that way. The wired ports on the SR20000G act like a wireless bridge, allowing you to connect a computer with out a wireless card into an existing wireless network.

You must already have a wireless network for this product to be useful.  It only works as a wireless repeater to expand coverage for an existing wireless network, it does NOT work as an access point or router to create a WiFi network.

If you would like to simply add a WiFi network to your existing Cable internet connection, Amped sells an access point just like this (the AP20000G) that can be connected as you describe.
