janiani As a newbie, its advisable to state the Roku model, firmware version, type of connection (wired/wireless) as well how its connected (HDMI, through an AVR, etc). As atc98092 has stated, the Roku assigns the IP address not the user. You may be experiencing channel congestion is using WiFi or in lay terms, too many others using the same channel making it difficult for the Roku to connect. The best way to determine this is through installing an app like WiFi Analyzer for Android or something similar for iPhone. Open the app, check the channel graph then tap the circular icon to learn each SSID and the channel its using. Log into the router, disable 'auto' from channel selection and choose one with less congestion. The star icon rates channels by strength.
