To know your exact (wired) ethernet card you can run:

$ lspci -nn | grep Eth
08:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller [10ec:8168] (rev 03)

The RTL8111/8168B card is supported by the kernel.


To know your exact wireless card you can run:

$ lspci -nn | grep Net
0e:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)
  • This card is supported by the broadcom driver, follow instructions here: Broadcom BCM4312
  • This card is partionally supported by the kernel, see here [b43 known PCI devices [1]]


To find out the exact touchpad you can run:

$ cat /proc/bus/input/devices
I: Bus=0011 Vendor=0002 Product=0008 Version=7321
N: Name="AlpsPS/2 ALPS GlidePoint"
P: Phys=isa0060/serio1/input0

U: Uniq=
H: Handlers=mouse1 event8 
B: EV=b
B: KEY=420 0 70000 0 0 0 0 0 0 0 0
B: ABS=1000003

This laptop has the following touchpad: AlpsPS/2 ALPS GlidePoint. Follow the instructions for the AlpsPS/2 ALPS GlidePoint here: Touchpad_Synaptics
