Hi Krish,
Connect to internet / router from more than one pc.
There r very simple steps,
login with admin / admin -> go to advance setup -> go to port mapping ->u will see there is only eth0_2 is checked. eth0_2, eth0_3, eth0_4, eth0_5 are your ports that is four ports. only one u checked means, only one can access your router or internet at one time. if u want to connect 2 pcs at a time then check for eth0_3. save setting. now u can access both from desktop and wireless laptop..
i think now things will be ok !
