Abstract: A hotspot communication stabilization system includes a hotspot communication stabilizer. The hotspot communication stabilizer includes a connected device address search unit and a comparator. The connected device address search unit serves to obtain at least one connection address from a communication host device at regular or irregular intervals. The connection address is an address of a peripheral communication device connected to the communication host device and is stored in a connection address table. The comparator serves to determine whether there is a missing address in the connection address table at a current time by comparing two connection addresses of the peripheral communication device at two adjacent times. The missing address is sent to the communication host device and the communication host device re-establishes a hotspot signal connection to the missing address corresponded to a corresponding peripheral communication device.
