@Haloen97-
Your problem may have been caused by a recent update to your router that affects some Roku models. This has been reported lately with equipment from Comcast/Xfinity and Cox, but there may be others.
Affected users report their Roku locates the network and reports the connection strength but then fails to connect. The solution is to reconfigure the router to switch it from g/n wifi protocols as set by the update back to b/g/n. If you don't have access to your router's control panel you may have to have your internet provider do it for you.
