Internet connection is spotty with Ruckus

[luckusruckus]

When connected to the Ruckus, my internet can be slow to load websites intermittently. It has been like this ever since our power went out one day. I have unplugged and replugged my modem and Ruckus many times. Not only is it slow to load websites, quite often it even disconnects from the Ruckus network. When I am connected directly to my AT&T modem's wifi, the connection appears to be much more stable/fast than the Ruckus. Please help
