Help & troubleshooting for network issues, including connecting your device to your home Wi-Fi network, connecting to public networks, troubleshooting wireless issues & ethernet connections, and optimizing streaming performance.
I can have full strength WiFi connection on all things like cell phone, tablet and computer, but the Roku buffers constantly and loses signal. It takes a good hour to watch a 20 minute show. About a year ago I was upgraded because of a similar issue with the Roku express, is this possibly a very similar issue? I have reset my WiFi many times, but the issue only stands on the Roku. Anyone have any insight other than Spectrum sucks?
First, it's possible to be too close to the router, so you should have a few feet between them at the minimum. Next, Roku players appear to be more sensitive to interference from other devices. Since the Express only supports 2.4 GHz, there's only a limited number of channels you can try. If you have a wireless device that you can install WiFi scanning software and see what's nearby, that would be great. But if that's not an option, then you can just experiment with different channels in your router.
There are 11 channels, labeled 1 to 11. See what channel you're using now. Your router is probably set to Auto, and might not tell you which one it's using, so look at your Network screen on the Roku. It will tell you. If you're currently using a channel in the middle (5-7) try a channel at either end. If you're already at an end, try a middle channel or the opposite end. You might find a quieter place on the band and improve your Roku connection speed.
Speaking of speed, have you done a connection test under the Network menu? If the WiFi is working properly, it should be somewhere close to your Internet connection speed. If you aren't positive what that is, go to Speedtest.net and test your network, preferably on a wired computer.
