Recommended download speeds are:

  • Basic Streaming - 1.5Mb or 1,500K
  • HD Streaming - 5Mb or 5,000K
  • Full HD or Super HD Streaming - 10Mb or 10,000K

2 Range Check

The device needs to be within a reasonable range of the router in order to connect and have the best connection speeds.

  • In general, in most homes, you can be up to 30 feet from your router for a decent connection.
  • From 30' to 50' away, the speeds will be slower, and may drop occasionally, but it should be usable.
  • Greater than 50' away, and the signal will most likely be too weak to overcome interference. The speeds will be slow, and the connection may be sporadic.

The above numbers are approximates only. Optimal range may vary based on router make and model.

? Is your TV within reasonable range of the router?

Your router may need to be relocated to a more centralized location in order to provide better coverage for all your devices.

Bad Placement

Since this appears to be a range issue that can be resolved by putting the router in closer proximity to the device's intended use area, we recommend moving the router to a more centralized location.
If the wireless signal is not reaching the device and moving the router or device in closer proximity is not possible or doesn't resolve the issue, the best option for wireless connectivity is to get a range extender.
