Hi Don and Welcome. I'm Joel and I look forward to assisting you today with your question. Can you tell me how you currently have your Time Capsule setup and the FIOS router and also what computer your using?
Thanks Don. I think you have two options for setup. Since your FIOS router has wireless and also the Time Capsule, which one do you connect your computer and clients to?
If you connect wireless to the Time Capsule, you should connect the FIOS routers LAN port to the Time Capsule WAN port. Then join your Macbook to the Time Capsules wireless network. See if that works. The second way is to use the FIOS routers wireless, so you join your Macbook to the FIOS wireless network, then you would attach the Time Capsule LAN port to the FIOS routers LAN port (so you'd be using the FIOS router as the central point then attaching the Time Capsule to that
Since they are both in the same location its easier to select one to act as a wireless access point. So your connecting your computer and any other wireless computers to the FIOS wireless. I would attach your Time Capsule WAN port to the FIOS routers LAN port and then see if it shows up.
OK, so your desktop is directly connected to the FIOS routers with an ethernet cable. In that case, still attach the Time Capsule WAN port to the FIOS router LAN port
What color is the light currently?
Thanks. Are you able to follow the steps from page 16 here successfully?
