how can i remove limited connectivity from LAN connection

please explain me how can i overcome limited connectivity problem?

Please be more specific as to what your particular problem is, and what you want to do to resolve it. Just saying "remove limited connectivity from LAN connection" is not particularly helpful in understading your real problem.

Your "limited connectivity" refers to the fact that your Windows system was not able to acquire and IP address from a DHCP server, but did configure itself with an Automatic Private IP Address (APIPA) address.

Do you have a DHCP server on your network?

open up a command prompt. if in XP, go to start, click run, type in 'cmd'
if in vista, or win 7, go to start, and just type 'cmd'
a command window will open.

type the following (without quotations):

"ipconfig/release"

hit enter

then when you can type again, type the following (without quotations):

"ipconfig/renew"

hit enter

see if that works for you. ipconfig/release is a command that essentially wipes all internet connectivity including IP address, gateway, etc...
ipconfig/renew refreshes all that information... basically, it's like pressing the reset switch on your internet connection.

best of luck
