It is absolutely essential that whenever you change the device connected directdly to a cable modem that you do a complete reset of the network every time you make the change. To do this, shut everything off. Wait about 5 minutes. Turn on the modem first, and wait another 5 minutes. Then turn on the device that is connected directly to the modem .

 

Cable modems "remember" the last device connected and will never connect to another device until this reset procedure is performed.
