Weak signal and overheating issue on Roku Premier 3920X
Since past few months, I have noticed that the wifi signal that Roku detech is extremely weak (1 bar) as compare to full bars it used to detect. Also I have noticed that it is quite warm on touch even after 10 minutes of use. It wasn't the case few months ago. Even if I put the router next to the Roku, it only detects 1-2 bars. All of my devices are connecting to wifi with full strength in the same location without any issues.
Furthermore, if the affected device is a Roku Express or Roku Premiere, please note that both devices are only compatible with wireless b/g/n networks on the 2.4 GHz spectrum. Ensure that your router is broadcasting a 2.4GHz Wi-Fi network for the device to connect to. You can check your device model by navigating to Settings > System > About.
