Then, what does ipconfig renew do?
Ipconfig /renew is the command used to tell the DHCP server that your computer wishes to join the network and needs to be configured with an IP address to communicate with the other devices on the network.
Open a command prompt window or the run command and type "ipconfig /release & ipconfig /renew" on one line in the command window without the " to do both release and renew in one hit. Windows will release and forget the last ip info you had including the DHCP server and the look for a new one. No more having to reboot.
