Electronic device that improves wireless network transmission quality and operating method therefor

Abstract

In an electronic device provided in the disclosure, an external antenna device includes at least one directional antenna, a wireless communication module is electrically connected to the external antenna device, and a processing circuit is electrically connected to the wireless communication module. The processing circuit collects broadcast information of all wireless routers in a current environment through the wireless communication module and the external antenna device; the processing circuit selects one of the wireless routers with the lowest interference based on the broadcast information for connection, and then rotates the external antenna device sequentially according to a plurality of azimuth angles, so that the processing circuit obtains reference information corresponding to the wireless communication module through the directional antenna; and the processing circuit selects an azimuth angle corresponding to the maximum reference information as an optimal azimuth angle to rotate the external antenna device to the optimal azimuth angle.
