Advanced security and other questions.
So, today had to upgrade my Xfinity modem/router. Which I had in bridge mode and wi-fi disabled, and just used my router. What they replaced it with was the Xfi white cube one. Had to use the app to activate it, went pretty smooth. I was looking to set it up the same as the old one in bridge mode since I have my own Wi-Fi router. While connect to the Xfinity modem/router Wi-Fi I found no bridge mode setting in the app or the modems interface. So, I plugged in my router and it works great with out bridge mode. Now I have 2 Wi-Fi connected devices. My router and the Xfi modem/router.
Now, as long ago before on here about Xfinity`s Advanced security, I take it`s still not worth activating?

FWIW. If you are hanging a stand-alone / separate router off of the gateway device, and the gateway is not in *bridge mode*, you are cascading 2 routing devices which will result in an undesirable "double NAT" condition on your home network.
Google "double NAT" for info about its potential pitfalls. It may break some applications.

Why rent their combo device at all when you are only using part of it ? Consider purchasing a compatible straight cable modem at retail to use with a good stand-alone router and save the rental fee. It will pay for itself in fairly short order.

Do a hardwired (not WiFi) speed test with the router in the mix and then do another test hardwired directly to their gateway and compare the results. A ten-year-old router is a bit long in the tooth, but it also depends on which speed tier you are subscribed to.
