Hello I've been successfully running internet on my laptop as a client through my XP home network with internet connection for some time now. It's not used very often but has always worked OK. Now suddenly I'm getting a 'Limited Connectivity' message and cannot see my network unless I manually configure IP addresses, but still can't get onto the internet. Cant even ping addresses with ip numbers or domain names. All I've changed is my ISP (still on broadband, same router) and installed Comodo firewall, which has automatically detected my network and sees the incoming connection. What's up here, any ideas?
