Ok, perfect. We need to configure the router to a switch (Disable DCHP), assign it a new IP (192.168.1.200), enter a new password, set up wireless. I gave you instructions for everything but the wireless. You need to take the modem out of the process. Unplug the cable from the modem at the router. You will only have a PC connected to a numbered port. If you have to, keep this thread open in another browser window (not tab).
