TP－LINK的网卡使用的是Realtek的芯片，因此Realtek的网卡驱动适用于TP-Link的网卡。在此以TP-LINK的TG-3269C为例,该网卡使用的是REALTEK 8169系列芯片,同理可以用此方法安装所有使用REALTEK系列芯片的网卡。
先在此页找到RTL8169在UNIX下的驱动。下载后解压到本地磁盘， 先查看是否已经加载了RTL8169的驱动模块：
# lsmod | grep r8169
如果已经加载则先卸载
# rmmod r8169
然后在驱动程序的目录处执行如下命令：
make clean modules
make install
depmod -a
insmod ./src/r8169.ko
这时用lsmod | grep r8169可以检测到系统已经加载了驱动模块8169，这时网卡已经可以正常工作了，如果网卡仍然不能正常工作，一般表现为速度指示LED很快的闪烁，此时应该关毕网关的自动检测，指定传输速率，先用命令rmmod r8169卸载掉已加载的模块，然后用命令 insmod ./src/r8169.ko speed=100 duplex=0 autoneg=0 予以强制指定工作模式，设定传输速率为100M,如测试仍不能，请尝试设定其他数值（分别可设为10,100,1000）。这里需要说明的是，本人根据经验得出，在speed=10 的条件下可以在大多数机器上确保网卡工作正常，在speed=100及1000的情况下，某些时候不能正常工作。这个方法同样可以解决使用realtek系列芯片的网卡不能正常工作的问题。

下面附上RTL8169的UNIX下驱动安装的官方说明：
This is the Linux device driver released for RealTek RTL8169S/8110S, RTL8169SB/8110SB, and RTL8110SC.
- kernel source tree (supported Linux kernel 2.6.x/2.4.20 and latter)
- compiler/binutils for kernel compilation
Check whether the built-in driver, r8169.ko(or r8169.o for linux kernel 2.4.x), is installed.
# lsmod | grep r8169
If it is installed, please remove it.
# rmmod r8169
note: If the built-in driver cannot removed by rmmod, please edit /etc/modprobe.conf and comment ‘alias eth0 r8169′. Then, remove it again or reboot your computer.
Unpack the tarball :
# tar vjxf r8169-6.aaa.bb.tar.bz2
Change to the directory:
# cd r8169-6.aaa.bb
If you are running the target kernel, then you should be able to do :
# make clean modules (as root or with sudo)
# make install
# depmod -a
# insmod ./src/r8169.ko (or r8169.o for linux kernel 2.4.x)
You can check whether the driver is loaded by using following commands.
# lsmod | grep r8169
# ifconfig -a
If there is a device name, ethX, shown on the monitor, the linux
driver is loaded. Then, you can use the following command to activate
the ethX.
# ifconfig ethX up
,where X=0,1,2,…
1. Set manually
a. Set the IP address of your machine.
# ifconfig ethX “the IP address of your machine”
b. Set the IP address of DNS.
Insert the following configuration in /etc/resolv.conf.
nameserver “the IP address of DNS”
c. Set the IP address of gateway.
# route add default gw “the IP address of gateway”
2. Set by doing configurations in /etc/sysconfig/network-scripts
/ifcfg-ethX for Redhat and Fedora, or /etc/sysconfig/network
/ifcfg-ethX for SuSE. There are two examples to set network
configurations.
a. Fix IP address:
DEVICE=eth0
BOOTPROTO=static
ONBOOT=yes
TYPE=ethernet
NETMASK=255.255.255.0
IPADDR=192.168.1.1
GATEWAY=192.168.1.254
BROADCAST=192.168.1.255
b. DHCP:
DEVICE=eth0
BOOTPROTO=dhcp
ONBOOT=yes
There are two ways to modify the MAC address of the NIC.
1. Use ifconfig:
# ifconfig ethX hw ether YY:YY:YY:YY:YY:YY
,where X is the device number assigned by Linux kernel, and
YY:YY:YY:YY:YY:YY is the MAC address assigned by the user.
2. Use ip:
# ip link set ethX address YY:YY:YY:YY:YY:YY
,where X is the device number assigned by Linux kernel, and
YY:YY:YY:YY:YY:YY is the MAC address assigned by the user.
1. Force the link status when insert the driver.
If the user is in the path ~/r8169, the link status can be forced
to one of the 5 modes as following command.
# insmod ./src/r8169.ko speed=SPEED_MODE duplex=DUPLEX_MODE autoneg=NWAY_OPTION
,where
SPEED_MODE = 1000 for 1000Mbps
= 100 for 100Mbps
= 10 for 10Mbps
DUPLEX_MODE = 0 for half-duplex
= 1 for full-duplex
NWAY_OPTION = 0 for auto-negotiation off (true force)
= 1 for auto-negotiation on (nway force)
For example:
# insmod ./src/r8169.ko speed=100 duplex=0 autoneg=0
will force PHY to operate in 100Mpbs Half-duplex(nway force).
2. Force the link status by using ethtool.
a. Insert the driver first.
b. Make sure that ethtool exists in /sbin.
c. Force the link status as the following command.
# ethtool -s ethX speed SPEED_MODE duplex DUPLEX_MODE autoneg NWAY_OPTION
,where
SPEED_MODE = 1000 for 1000Mbps
= 100 for 100Mbps
= 10 for 10Mbps
DUPLEX_MODE = half for half-duplex
= full for full-duplex
NWAY_OPTION = off for auto-negotiation off (true force)
= on for auto-negotiation on (nway force)
For example:
# ethtool -s eth0 speed 100 duplex full autoneg on
will force PHY to operate in 100Mpbs Full-duplex(nway force).
