I recently upgraded to 450Mbps Internet speeds and at the same time added Xfinity Home Security. Prior to the Xfinity Home install I had 450Mbps download speeds. Yesterday the Xfinity tech installed the security system which required an Xfinity Home Security Router that he said must be connected directly to my cable modem (I own the cable modem and my home wifi router). Now the Internet speeds are stuck at about 100Mbps. Suspecting the Xfinity Home Security Router, I looked and confirmed it is a 10/100Mbps router.
Can someon confirm that having this Xfinity Home Security Router connected directly to the cable modem is a requirement? Seems silly since it prohibits you from achieving the Internet speeds you pay for. I tried to connect my WiFi router directly to my Cable Modem and it didn't work anymore. If this is a requirement, I will cancel my Xfinity Home Security service before the 30 day period.
Solved! Go to Solution.
To add, don't forget you will have to powercycle the modem when changing the device directly connected to it to get a connection.
After placing the Xfinity Home Security Router after my home router internet works great and now has the 450Mbps, but Xfinity Home cannot connect. Any other thoughts? Is it possible the installer configured the Xfinity Home Security Router in a way it must be installed right after the cable modem?
Not that I'm aware of. This is a brand new home router and everything else I've connected to it works fine. I also went into my home router app and ensured none of the ethernet connections were paused.
A Comcast employee helped me last night identify that I may have a bad port on my new home WiFi router. After switching to another everything works. Thank you all for your help!!
