Restarting your Roku device, and your wireless router/modem is a great first step. Replacing the batteries in your remote can help. Changing the wireless broadcast channel on your wireless router, to one that isn't in use by another nearby wireless network, can reduce wireless interference and be extremely effective in improving remote functionality.
The remotes for my two streaming sticks work fine now. The issue was the internet outage and when the internet came back some settings on my modem had changed. I had to finally call century link about three times to get the issue sorted out.
