I have a simple wireless network with a desktop and laptop. Everything was working just hunky dory. I had Hamachi set up on the laptop, then recently uninstalled it. After the uninstallation, I can no longer access the internet or my network from the laptop. If I do an ipconfig, the DNS suffix and default gateway are both empty. I do have a valid IP address and subnet mask. I've had this problem before when I installed Hamachi - that's why I'm thinking it's suspect. I resolved it by reformating my hard drive. I don't feel like doing that this time around - there has to be a better fix. I went in and manually set the IP address, default gateway, DNS suffix, and subnet mask, but it didn't solve the problem. Any help would be appreciated.
