My computer is set for automatic windows updates. This afternoon, my computer updated, and needed a restart. I clicked through the prompts and hit "restart now", and since the reboot, I do not have internet access. I use a cable modem hooked into a router. The router has three computers hooked into it. The other 2 are working fine. The working computers are prompting me that I have windows updates to install as well, but I have not done so, as I do not want to lose internet on all of my machines. The lights on my router and modem are currently functioning properly. Any ideas?
