Thank you for reaching out here. If you have tried all the steps provided earlier, and are still experiencing service issues, I would be happy to look further into that from here.

Have you had a chance to see if any of those troubleshooting tips apply ?

We have had stable internet for our entire time with XFINITY.  None of the troubleshooting works, most of the time I can’t connect to Xfinity to troubleshoot because of the instability.  Our modem has been replaced three times in the last year. We’re supposed to have a split connection with 2.4 and 5.0, but only have 2.4.  I tried a chat with a representative ~a month ago, and they tried to upsell equipment and plan.  I’m beyond frustrated paying for a service that’s not provided.

Please create a new topic of your own here on this board detailing your issue. Thanks. The original poster has not returned. 6-month-old dead thread is now being closed.

For future reference, it is better to submit your own post as it creates a ticket to get help, and posting on someone else's older thread can delay getting help.
