hotspot gets disabled after reboot or restart...

hi,

i have setup a hotspot using 3G dialup modem on a RB7112 board.

it works perfectly but whenever the router is rebooted or restarted after shutdown the hotspot goes RED as is disabled.

what is the problem?? where and why is it behaving this way?

this DNS entries are from the ISP whose 3G USB stick i am using. i have a feeling this issue has to be something related to DNS..

please help!!!
