If your network module is exist in the blacklist.conf file disable these lines with # characters and reboot your system. After the reboot if you have still have the same network problem then run nx_nic_tools_post.sh script in /opt/nx_nic directory and reboot the system. This small script belongs to the HP nic utiliy, If you already installed it this directory should be exist.
