This question already has an answer here:
I would like to reinstall the driver of my wifi card. In order to find out the name of my driver, I have used:
sudo lshw -C network
and the output for the wifi card is
*-network DISABLED description: Wireless interface product: RTL8723BE PCIe Wireless Network Adapter vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:04:00.0 logical name: wlan0 version: 00 serial: 4c:bb:58:dc:ad:10 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=rtl8723be driverversion=4.2.0-30-generic firmware=N/A latency=0 link=no multicast=yes wireless=IEEE 802.11bgn resources: irq:19 ioport:1000(size=256) memory:90400000-90403fff
Therefore, I think the device name is
RTL8723BE PCIe Wireless Network Adapter.
Can anybody guide me how to reinstall its driver again?
