If your Roku device keeps buffering, drops Wi-Fi, or shows a “weak signal” message, it’s usually a problem with the wireless connection between your Roku device and your router. Try these advanced troubleshooting steps to resolve your connection issues.
Use your Roku remote to check your current signal:
If the signal is Poor or Fair, that means your Roku device isn’t getting a strong Wi-Fi signal. Move on to Step 3 to improve it.
How your Roku player and router are positioned makes a big difference:
After moving things, go back to Settings > Network > Check connection to see if your signal and download speed improved.
If your Roku device keeps failing to connect:
If your Roku player shows a “low power” message or randomly restarts, plug it directly into a wall outlet instead of your TV’s USB port.
If you’ve tried the basic fixes and the problem continues, these extra steps can help.
If your router and Roku both support 5 GHz Wi-Fi, switch to that network (usually named something like “MyNetwork_5GHz”).
If all else fails:
IPv6 is the newest way devices connect to the internet. It was created to replace the older system (IPv4) and helps make sure there are enough internet addresses for all current and future devices.
