ThinkPad T450 cannot detect wifi adaptors
My T450 suddenly could not find wireless devices with lcpci
.
$ uname -r 4.2.0-42-generic $ lspci -nn | grep -i net 00:19.0 Ethernet controller [0200]: Intel Corporation Ethernet Connection (3) I218-V [8086:15a3] (rev 03)
I upgrade BIOS version, reboot, and press Fn + F2
and now I can use wireless connection.
