1, the 300M of the router refers to the router allows the maximum transmission bandwidth of 300M, not the network speed of 300m.
2, the wireless card 150M means that the wireless card allows the maximum transmission bandwidth of 150M, not 150m network speed.
3, determine the network speed is the user to the broadband operator to apply for how much broadband bandwidth. For example, if the application is 20M, it is routed to the wireless network card or 20M. When the applied broadband is greater than 150M (such as the application is 350M), only 300M can be obtained after transmission to the router. When transferred to a cardless network card, only 150M is obtained.
4, wireless network card device and routing connection also due to distance, obstacles and other reasons caused by the transmission speed decline. General wireless routing and wireless device connection distance can not be too far, the farther the signal is worse, the slower the speed.
