“Boost a device’s WiFi connection” feature no longer available in my Xfinity app

sheas19 Thank you so much for your post for help with your storm-ready pro Wi-Fi extender and boost options not showing. There have been some issues with the devices in the past no longer showing if a modem change is done after activation. Have you by chance made any changes to the modem since setup up the storm-ready Wi-Fi extender?  

My gateway (XB8) was replaced twice one time during a technician visit.  Shortly after I upgraded my internet and activated the XB8 gateway, I started having a major drop in my internet speed.  I had a technician come out to my house to diagnose the issue.  Unfortunately, the tech wasn’t able to find anything wrong, but he ended up replacing the XB8 two times while he was at my house.  Ultimately, another technician had to come out to my house the following week, and he was able to find the reason for the slow internet — the coax cable end was bad and had to be replaced.  To my knowledge, that’s all that has been done ever since my new gateway was activated back in June/July of this year.

I also have Xfinity Pro my modem was changed my internet speed has decreased had three technicians come out and I no longer see boost the device in Xfinity app

I'm having the same issue. Did you ever figure out what's going on? I have a similar story just like yours three technicians two modems Exchange lagging internet went on Xfinity app boost a device up to 8 hours was on there for 2 days that was 2 weeks ago it is no longer there for me. I have done everything I mean everything to try to fix this problem technician, troubleshooting, chat messaging, calling Xfinity, and even having a priest come to my house to bless my modem and nothing works. Please tell me you found a solution?
