Release the IP address. (Method varies by router manufacturer)
Turn off router, ethernet hubs/switches, and the cable/DSL modem.

to avoid all the hassle with the release renewal of your ip address. just set a static IP address to your computer and avoid all the hassle. I typically will only let WIFI users on my network connect with DHCP which automatically hands out IP addresses.

what you need to to is go to start\control panel\network and internet\network connections
you should have one but some computers have two for instance if you have a ethernet adapter and wifi adapter both use seperate ways to connect to your router one wired one wireless. depending on how your computer connects you want to go to the adapter where it connects through. so for instance if i have a wired connection to my router from my computer i'm going to go to the wired adapter.

right click on the adapter of choice then go to properties. go down to TCP/IPv4 select that and then go to properties it should come up with a selection to obtain IP automatically or manually. click on use the following IP address and give it an IP in the range of static IP's of your router for instance on mine DHCP takes all IP numbers 192.168.1.100 through 192.168.1.200 . but I can set a static IP to the computer of 192.168.1.20 and the router will recognize that this is a static IP and that it will never change. so give your computer an IP and then subnet is usually 255.255.255.0 and the gateway is the main router that is spliting your WAN from LAN. Typically 192.168.1.1 some routers are 192.168.0.1 though. leave DNS automatic and save settings. this way you will never have to release nor worry about IP address conflicts. hope that helps
