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.

10. Relocate Router Check

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

11. Router Relocation

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.

12. Range Extender

If wireless signal is not reaching your device, and relocating your router or the device itself to be in closer proximity is not possible or doesn't resolve the issue, a great way to boost wireless signal without replacing existing equipment is to acquire and install a range extender. Range extenders work with your existing wireless router as a type of wireless repeater used to expand the reach of wireless signal in your home.
