Samsung patents Wi-Fi fix that blocks bad connections to save data

This patent describes a method for electronic devices to monitor multiple Wi-Fi connections to an external device. If one connection shows signs of poor quality, such as frequent data retransmissions, the device restricts communication on a related link to prevent errors.

Why it mattersIt aims to improve the stability of Wi-Fi connections by automatically managing data flow when signal quality drops.

In the filing’s own words

Various embodiments of the disclosure relate to apparatuses and methods for WLAN communication in an electronic device. Example electronic devices according to the present disclosure may include a communication circuit configured to support WLAN communication and at least one processor, wherein the processor is configured to identify the number of times of reception of retransmission data of each of a plurality of links with an external electronic device for a designated time period, based on the number of times of reception of the retransmission data, when the plurality of links includes a link satisfying a designated error condition, identify another link related to the link satisfying the designated error condition, and restrict the WLAN communication via the another link related to the link satisfying the designated error condition.

What exactly they claim (claim 1)

1. An electronic device comprising: a communication circuit configured to support wireless local area network (WLAN) communication; at least one processor, comprising processing circuitry, operatively connected with the communication circuit; and memory storing instructions, wherein the instructions, when executed individually and/or collectively by the at least one processor, cause the electronic device to: establish a plurality of links with an external electronic device via the communication circuit; identify at least one of channel state information or a number of times of reception of retransmission data of each of the plurality of links for a designated time period; identify a first link among the plurality of links satisfying a designated error condition related to the identified at least one of the channel state information or the number of times of reception of retransmission data; based on identifying that the plurality of links includes the first link satisfying the designated error condition, identify a second link related to the first link among the plurality of links, wherein the first link is configured as a retransmission link for the second link; and restrict the WLAN communication including transmission and reception of data via the second link.
