一，lspci命令显示:
03:00.0 Ethernet controller: Attansic Technology Corp. L2 100 Mbit Ethernet Adapter (rev a0)
这个是以太网卡，有线宽带，对否。
一，lspci命令显示，没有无线网卡设备，对否？
二，无线网卡可以集成在cpu或其它芯片中么？

用lspci能够查看到你的设备如下内容是我的电脑上的以太网和无线网的网卡芯片说明：
02:00.0 Ethernet controller: Broadcom Corporation NetLink BCM57780 Gigabit Ethernet PCIe (rev 01)
03:00.0 Network controller: Atheros Communications Inc. AR928X Wireless Network Adapter (PCI-Express) (rev 01)
然后谷歌一下，你的网开在linux下的驱动（内核配置里选的哪个）
然后使用lsmod查看一下其实直接lsmod也能找出来名字
ath9k_common 13781 1 ath9k
ath9k_hw 391523 2 ath9k,ath9k_common
ath 19387 3 ath9k,ath9k_common,ath9k_hw
snd_seq_device 14172 3 snd_seq_midi,snd_rawmidi,snd_seq
cfg80211 178679 3 ath9k,mac80211,ath
最后rmmod就行了
主要是找到对应的驱动支持哪些设备

貌似linux原本是不带wifi驱动的把
驱动都在/lib/modules/（version）/kernel/drivers这个目录下面，也不需要删除，如果加载了驱动，直接卸载了，用rmmod命令就可以了
