Today I'm going to describe the tool's and methods to use any Xfinity wifi for free. *Please note that this is intended for educational purposes.
*Programs Required:TMAC https://technitium.com/tmac/
First, go to the website above and download the proper one for your os and arch type.Once it is downloaded, open the program. A list of networks will appear. Choose your adapters and go to the 02 oclet box then click it and choose a random mac. Then click "change now."Viola! You can now use Xfinity. The only caveat is that you'll have to change your mac every hour, but it works.Now, for those of you who are more daring -You'll need to know basic command shells. This will show you how to backdoor almost any arris modem almost 600,000 modems have this flaw https://w00tsec.blogspot.com/2015/11/arris-cable-modem-has-backdoor-in.html
but beware, my fellow Cybrarians, this link is used for educational purposes only so know your local laws and don't be stupid.I also found a website for pawning the daily password generator for arris allowing you to be an admin: http://www.routerpwn.com/Arris
and yet another great resource is: https://packetstormsecurity.com/files/123631/ARRIS-DG860A-WPS-PIN-Generator.html
I was lucky to be connected when they reset the router. It sent me the <get> function which in return gave me the glitch to use Xfinity free all I want if the need should arise.I hope this information has helped you. Sorry that I could not post all the details, but these are the links to the methods I have tried and hope it helps you like it has me!
Pro-Tip - I found a glitch not tested after using TMAC. It eventually glitched making it to where the free trials go away and I stay connected.Good luck!
