beaglebone black HD camera cape issue

Hello everyone

I need a help over this issue. I’ve bought a beaglebone black and its hd camera cape, Whenever i put the cape on the bbb board, the board is able to communicate computer from PuTTY terminals only by serial communication setting and doesn’t work using SSH setting. Hence i cannot provide a internet connection to beaglebone using serial communication.
The board runs fine when the cape is unattached. it is even able to connecte= to internet using serial communication.
