Hi,

Do you experience problems with other WiFi hotspots?

system light must flashing every second or one second . that is mean the system work correctely . but if the light was flashing rapidly , i think there is problem with system .
reset router , if the light keeps flashing , change the router

the router without any Modem WITH internet is useful. You must have Moden with BSNL broaband. Remember the router the only function is amply the signal for internet for use in wireless.

God bless you

Most routers have a reset in the back. Hold it in till it cycles. This will clear all custom settings, and load defaults like new.

yeap it should be the firewall, here is the manual http://www.tp-link.com/resources/software/201161017075118.pdf
think this should help you.
But if you want my expertise, make the tp-link as a router and vdsl just the internet line. connect it to router wan and buy a switch for all your devices.That should be the safest and smartest way.
