These Step by step guied for Linksys manage network card model number is LNE100M. and driver file comes with card cd under drivers-->Linux folder. and i done this final and working steps under redhat linux 9.
why i install this new driver:
Actulay i install linux and it pick any via chip lan card was showing under system setting-->network-->edit-->hardware device and was not active i forceling assigned stetip ip and make it active , then it start ping it self but was not ping nay other remort computer on my network. now ist fine


mkdir /tmp
copy lne100ml.tar file in tmp folder from network driver cd under drivers-->Linux
tar xvf lne100ml.tar
cd lne100m
Compile the driver source files and it will generate lne100m.o
for compile
make
check kernal version with
uname -r
after compile copy lne100m.0 file in to mudules driver folder
if kernal version is 2.4.x then path is ,,
/lib/modules/KERNEL_VERSION/kernel/drivers/net/
if kernal version is 2.2.x kernel, then path is ,,
/lib/modules/KERNEL_VERSION/net/
make install
edit configuration file (/etc/modules.conf or /etc/conf.modules,it
depend on your Linux distribution)
for loading kernel modules. Make sure there is the following content in the
configuration file, where # is
interface number (eg: alias eth0 lne100m):
alias eth# lne100m

Reboot now:
shutdown -r now

Use ifconfig command to assign the IP address, where # is network
interface number:
ifconfig eth# <IP> Exemple: ifconfig eth0 192.168.1.100

Check the interface works: ping any remort computer
ping <remote_host_IP> Exemple: ping 192.168.1.101
