I am assuming this is probably the 3920 Premiere (since you have only had it for a couple of years). You can verify this under Settings/Systems/About.
This device can only connect to your 2.4ghz band so has to be enabled and configured correctly. If you have a cable ISP (internet service provider) like Xfinity/Comcast, Cox, or AT&T, then there are known issues with some of their router firmware upgrades that are causing connection issues with 2.4ghz devices like the Roku Premiere.
If your situation is the above, then try changing the Wireless Mode in your router to b/g/n. (This setting will be located under the 2.4 ghz Wireless/wifi settings).
