It would be so great if Xfinity would offer the option to turn off the whole home network at night, instead of assigned devices because the kids can get around this by creating new addresses for their devices. My Circle app did this, but I had to use a router and it would be great if I could do this with just the Xfi gateway.
I don’t have a Xfinity router, but all the routers I've owned recently have given me a choice as to whether new devices join the network automatically, or require approval. If available, setting the latter would limit the appeal of just creating new addresses to get around restrictions.
Unplug it and take the power cord to bed with you ?
Lay down the rules !!! ?
