I just ordered a new C8 from Amazon. I followed the instructions and connected it to my router. Nothing was found. I then rebooted and unplugged the ethernet cable to try connecting via wifi. The network couldn't be found.
Just finished doing that. I also tried connecting my old router (not old, just wasn't used since I moved a couple weeks ago). It seems like the cox provided router wasn't recognizing any of the Ethernet ports until I hit the WPS button which seems very odd to me.
Anyway, after all that I was finally able to find the hub.
