This is the only way i know how to do it. . . shut down your computer, unplug your modem for about 15 seconds, then plug it back in. . Wait til a minute before turning on your computer. .. WAH-LA. . . Modem Reset = New IP Address!. . . . . . . OR, you can shut down your computer and leave your modem unplugged for 24 hours. . That surely will do it.
