Here's what happened. I was connected to my home router, working just fine. I decided to work in another room, and unplugged my laptop from the router to work. Later, when I went back and connected to the router, I had no connection. I rebooted several times, and still no connection. I tried ipconfig /release and then /renew, and the renew wouldn't work. Other computers connected can still access the internet and the router. I also tried swaping to a known good network cable from another PC and still had no connection. I let the laptop sit for a while (about an hour or so), came back, and the connection was up on my laptop.
Now, in the office, I can't aquire an ip through DHCP. If I manually enter an IP address and network settings, it works just fine. DHCP seems to be the only thing not working, but unfortunately, I have to use DHCP in the office. All other users in the office are working just fine for network.
