Update: my computer was reporting my ip address as 192.168.1.46
the router was reporting it as 0.168.1.46
I set up static IP - the router is now properly identifying my machine. But the problem is not resolved.
I disabled bonjour and I thought that fixed the problem but it did not.
When the problem occurs, I am able to ping and login to my router, and I can ping machines on my hamachi vpn, but not machines on the internet.
I don't know if this is related, but when I exit configuration of tcp/ip 4 I get
"Warning - Multiple default gateways are intended to provide redundancy on a single network (such as and intranet or the Internet). They will not function properly then the gateways are on two separate, disjoint networks (such as one on your intranet and one on the Internet). Do you want to save this configuration?"
I'm not sure what this is referring to, because I only have one gateway, but I disable IP 6 if that was causing a conflict.
Is it possible that Hamachi is causing the conflict and it is looking for an internet connection through Hamachi? (windows thinks it is an internet gateway?)
Here is my ipconfig
