Are you currently a Comcast / XFINITY subscriber? Read On!
If you're currently subscribed to the Cable company, Comcast - You may be running the risk of allowing the public to access your Home Network! This was their method on how to add millions of Hot Spots throughout the U.S.
You can find out if you are sharing a Public Network by taking your smartphone and checking for local Wi-Fi signals. Stand next to your Router/Modem during this time and if you have solid bars then most likely you've got Public Access.
While this may initially appear to be a good thing - it can lead to serious issues and possible Federal Prosecution. If you do not secure your Network YOU are liable for the traffic which flows through - do not be another statistic when it comes to a wrongful arrest!
XFinity allows ANYONE with a smart device to connect to YOUR Network for one complimentary hour, or permanently if they have a Comcast login. Not fun, right? So let's get that fixed!
Initially you were able to go into the Router/Modem itself and manually disable the Public Access / Xfinity Hot Spot. Now things are a bit more complicated:
First Go To: https://customer.xfinity.com/#/settings/security/hotspot.
Second: Sign into your XFINITY Account with your User/Pass
Third: Navigate to your Public Hotspot tab - click Turn Off.
This will disable the public access, but you'll still retain connectivity to your PRIVATE Network. No more worrying about Pirates on your Network :)
