You can use this app on your phone to test the speed near your Roku device to see if there's something causing poor coverage in that area. It also helps me to determine where areas in my house have poor coverage because the speed of the test drops off substantially when you take your phone into a poorly covered area. I use the Speedtest app on my phone to make sure I'm getting the advertised throughput with my ISP. Some folks setup all of their devices to keep up with email and the latest news feeds, which can cause a lot of traffic on your network and result in poor streaming/mirroring performance. 2.4GHz offers coverage for farther distances, but may perform at slower speeds.Īlso consider minimizing the number of devices on your wireless network during streaming. 5GHz provides faster data throughput at a shorter distance. The primary differences between the 2.4 GHz and 5GHz wireless frequencies are range and bandwidth. If you do have a current wireless network device you should try to connect both devices to the 5G side for faster throughput. The older 801.11g models didn't always have the bandwidth or processing power to be able to transfer data at high enough speeds to keep up with today's streaming devices and content. I would recommend you make sure you have both devices (the Samsung and Roku) as close as possible to your wireless router.Īlso check the wireless router to make sure it is capable. So 4 devices, two phones, two PCs, are not showing the Roku TV as discoverable which leads me to believe something on the TV is preventing us from seeing it on those devices.Often times this can be caused by your wireless setup.

I've fussed with wireless connections (we've got 2 routers/modems in our home), I've fussed with device managers, updates both to Miracast, graphics cards, all of that. The Roku TV is set up for Screen Mirroring. Now before anyone leaps to comments, Yes. So the issue is our Roku isn't showing up to the devices. It'll try to go to the TV before I even want it to go to the PCs or the phones. Spotify is obviously just an app, but works flawlessly. The only thing that can even connect to the Roku TV by means of Bluetooth or Wi-Fi is Spotify. Network connections are all on the same wifi/ethernet/band.įor some reason, none of our devices of any kind can locate the Roku TV. We have 2 Android devices and 2 Windows 10 PCs. Alright, so I've been at this for at least 2-3 hours, so here's hopin someone can help.
