This is a classic network card. Although Realtek RTL8191SE Kablosuz LAN 802.11n PCI-E NIC is not the best network card in the world, its various practical functions allow you to have a stable network environment, In terms of speed, the speed of Realtek RTL8191SE Kablosuz LAN 802.11n PCI-E NIC has reached the current mainstream level. It allows you to watch high-definition network videos smoothly, and it can process some simple network data packets by itself, disassemble the data packets into raw data and send them to the application layer. This will save a lot of CPU resources. But to realize this function, you must install the correct driver for it,It is compatible with most operating systems and can work normally even in the latest operating systems, 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. Realtek manufacturers also take this into consideration, so they add encryption function to Realtek RTL8191SE Kablosuz LAN 802.11n PCI-E NIC, 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, As long as you install the corresponding driver and make it work normally, it will allow you to browse information on the Internet comfortably.
