There are many factors that may affect the transfer performance on your home network.

You may have many devices requesting bandwidth at the same time, limiting your router transfer rate to any individual client. Movie streaming for example; takes a lot of bandwidth and may affect your router Wi-Fi throughput. Typically, reducing the number of concurrent transfers, obstacles and noise between your router and Wi-Fi client devices is the best way to improve transfer speed.

You can also move your Kwilt device closer to your router as the closer the devices are to each other, the stronger the wireless signal will be. If you are looking for a more powerful option you can try the new Kwilt2 or Kwilt3, which has a faster transfer rate.
