Troubleshoot video playback issues on Roku

HBO GO requires a solid Internet connection while streaming video. HBO GO will adjust video quality based on the strength of your network connection. If videos frequently buffer or are poor quality, a slow or inconsistent network connection might be the cause.

To improve video playback on your Roku player, try the following: 

Step 1: Check your connection speed

Check the speed of your Internet connection. To find out how to do this, go to Tips for improving the wireless connection, and follow the steps in the How to check your wireless signal strength section. To stream video, you need a high-speed connection with a minimum download speed of 3 Mbps. Test video playback at different times of the day (morning, afternoon, evening) to see if you get different results. 

Step 2: Power cycle your devices

Try power cycling your Roku and your network devices. Here's how:

  1. Unplug your Roku player.
  2. Unplug the power from your network devices (modem, router, etc.).
  3. Reconnect the power to your modem and then your router. Let each device power up before connecting the next.
  4. Plug your Roku player back in.
  5. Sign in to HBO GO and play a video.

Step 3: Try Roku's video playback tips

Try the suggestions in the following Roku article: Resolving video playback issues.

Step 4: Try a wired connection

For the best performance, try using a wired connection instead of a wireless connection. To do this, connect your Roku player to your home network using an Ethernet cable. 

Once you do this, make sure Wired (Ethernet) is selected in Network settings. Here's how:

  1. From the Roku Home screen, choose Settings > Network > Wired (Ethernet).
  2. Select Connect to wired network.

Step 5: Reset your Roku

If none of the above steps improve video playback, try performing a factory reset on your Roku. This will reset your Roku to its original settings (your Roku settings, Roku account information, and apps will be removed). Once you've reset your Roku, do the following:
  1. Install Roku software updates (from the Roku Home screen, choose Settings > System > System update > Check now).
  2. Reinstall the HBO GO app.
  3. Activate HBO GO again.
