Broadcom 802.11n Wireless SDIO Adapter is a network card launched by Broadcom manufacturer. Many computer manufacturers integrate this network card into the whole product, Because it has a relatively large signal transmission power, the heat generation is also a bit large, but fortunately, it does not affect normal use. With the support of the latest operating system, the chip will automatically reduce the frequency according to the actual situation to reduce the heat generation, Nowadays, more and more people are shopping online. Broadcom manufacturers also take this into consideration, so they add encryption function to Broadcom 802.11n Wireless SDIO Adapter, which can encrypt data before transmitting to external devices. However, this function is not enabled by default. The encryption function will be enabled only when you set it in the control interface of the driver, The original intention of Broadcom manufacturer to design this wireless network card is for those who have high requirements for network speed. Broadcom 802.11n Wireless SDIO Adapter can not only work well by itself, but also can be combined with wireless network cards of the same model to form a parallel working mode, so as to increase the bandwidth of the network, which can speed up the network data transmission speed, The most commonly used wireless data exchange protocols are 802.11b and 802.11a. Broadcom 802.11n Wireless SDIO Adapter also supports these standard protocols. Using these protocols, it can be connected to various new or old router devices, If your network card does not work normally, please check whether its driver is installed correctly, because this network card will not break easily.
