This is my first post on this site, so please forgive me if I am in the wrong spot. I am looking for some help on how to connect my wireless system. These are the items that I have. Comcast Cable Internet / Motorola Modem / Time Capsule 500GB / HP Photosmart 3210 AIO / 500 GB external HD. I have the cable coming into the house and running to the modem. An ethernet wire runs from the modem to the Time Capsule. I have anohter Ethernet running from the Time Capsule to the Printer. I then want to run a usb cable from Time Capsule to the External 500GB. Here is my problem. I cannot print to with the Ethernet connection. When I connect a USB from Time Capsule to the printer, it works. Why won't it work with the Ethernet cable. If I am able to get the Ethernet connectiong working, that leaves open the USB slot to connect my external HD. Any suggestions on what to do. I am lost. Thanks in advance for any help you can provide.
