What is going on? If I run traceroute google.com it outputs 192.168.0.1 for the first router (which is correct) and threee *'s for the rest. I have tried disabling the FireWall on the router (192.168.0.1) but that does not help. Any ideas?

And yes, I know there is an almost duplicate, and no, it did not help me.

the device after your router - most likely ISP device - is blocking traceroute/ping/ICMP packets. This is the reason for * * * istead of response times. –  mnmnc Dec 19 '12 at 20:03

The device after your router - most likely ISP device - is blocking ICMP protocol packets which means traceroute and ping packets.

This is the reason for * * * istead of response times

There are tools that could potentialy give the same result to you but they do not use ICMP - they use TCP. The example one is tcptraceroute. Check if this satisfy your requirements.

No go... tcptraceroute google.com outputs exact same thing as traceroute google.com... In fact, tcptraceroute google.com actually runs traceroute -T -O info google.com... –  BenjiWiebe Dec 20 '12 at 17:59
