Electronic device with network connection function and method for determining connection mode between electronic device and base station

The present invention relates to an electronic device having a network connection function, and more particularly to an electronic device having a network connection function and a method for determining a connection mode between an electronic device and a base station.

In general, when a wireless LAN device (such as a notebook with a wireless network connection) wants to connect to a base station, the wireless network device first selects the highest rate. The mode is used to connect to the base station for network connection. For example, if both the wireless network device and the base station support the 802.11n and 802.11g transmission modes, the wireless network device selects the 802.11n with a higher transmission rate. As a transmission mode between the wireless network device and the base station. However, in practice, considering the compatibility between the wireless network device and the base station, the signal noise caused by the air quality, and the collision problem encountered when the packet transmission between the wireless network device and the base station is transmitted. When using the 802.11n mode with a higher transmission rate, the wireless network device may not be able to successfully receive the packet data transmitted by the base station, so that the base station continuously repeats the transmission of the unsuccessfully transmitted packet data. The data transmission rate of the wireless network device is degraded, and even when the 802.11n is used as the connection mode, the data transmission rate of the wireless network device is worse than when the 802.11g is used as the connection mode. For example, if the wireless network device uses 802.11n as the connection mode under normal conditions, the data transfer rate should be 30Mb/s. However, in some cases, using 802.11n may actually only have The data transfer rate of 11~12 Mb/s, however, the data transfer rate of 802.11g mode with lower data transfer rate may be higher (about 20 Mb/s).

On the other hand, if the wireless network device has both a wireless network and a bluetooth component, in order to reduce the size of the wireless network device, the wireless network and the Bluetooth are generally used together in the wireless network device. Two antennas. However, if the wireless network device starts the wireless network and the Bluetooth function at the same time, the wireless network and the Bluetooth component will interfere with each other when the data is transmitted and received, and the data transmission and reception will be more frequent. The data transmission rate of the wireless network device is lowered.

Accordingly, it is an object of the present invention to provide an electronic device having a network connection function and a method of determining a connection mode between an electronic device and a base station, so that the wireless network device directly uses a lower rate connection mode.
