Network shows limited connectivity

After I installed Comodo firewall, My Network shows limited connectivity. how do I fix it? Do I need to configure my router or any settings in comodo firewall?

I installed comodo firewall 64 bit version without comodo’s DNS supports,(I’m using my ISP’s DNS) My rig: windows 8 64 bit, D-link DSL 2730U router with wi-fi, some daily apps I use: WAMP, hmailserver, utorrent, dropbox, skype, git, thunderbird… bitcoin-qt, VMware, app engine, DNSExit IP Updater are some common apps.
