Comparing wifi dongle with inbuilt wifi

[neku]

Usually a wifi dongle has to be connected to the USB port of a desktop for wifi connectivity, while laptops and android devices have inbuilt wifi. Is there any reason why the inbuilt wifi is more stable than using a wifi dongle?

The two function the same way. The only difference might be that the network band used by each of the two.

Built-in WiFi on a laptop or phone is often more robust than using a dongle because its chips are directly connected to the motherboard and have antennas placed in better positions. Dongles are often small and their antennas are not as strong, so the signal is weak and the speed drops. Also, inbuilt WiFi uses fast communication channels like PCIe while dongles rely on USB which can share bandwidth with other devices. It's a saying that a fish in the water is still raw.
