I'm trying to configure my COMTREND Wireless ADSL2+ Router vide model number CT-5361 for BSNL broadband... and am having trouble getting it connected to the internet. i found all the front panel LED indicators on modem are displaying correctly means ADSL, WAN, LAN, POWER indicators are green. I think some how i'm missing some modem setting.
