Problem with connection of networking and VOIP.

Go to your Run program on the computer that your are having connection problems with. Type cmd.exe in the box. When your DOS page appears, type in ipconfig/ release. Be sure to use a space between the / and the word release. After it releases, type in ipconfig/ renew, using the space as well. Close out of your DOS. Recheck your internet connection. Before you recheck it though, make sure that your computer's wireless password, if you are using any, are the same as your wireless router's password. Hope this helps.
