Why are my Internet Speed Test results different from what I expected?

Your wireless device is far from the wireless router or access point. Moving your device closer to your wireless router or access point will often result in improved speeds.
Verify if other wireless devices are sharing the bandwidth enormously. Whenever a wireless device connects to your Wi-Fi network, it competes with other devices for bandwidth. To solve this, set the QoS engine from router’s web UI to help improve your network performance.
The Internet speed from your ISP may be currently slower than expected.
