Samwathegreat I believe you may misunderstand the issue. I have had the problems you refer to for years as a AT&T customer. I was a Comcast customer with a AT&T phone with the xfinity app installed on my phone and logged in. My phone would connect to xfinity hotspots and many time have had to turn off wifi because the xfinity hotspot was too weak. You may be able to fix that problem by uninstalling all xfinity apps.
My problem and I am sure a number of others in this thread happened after installing a new xfinity gatway. My phone would autoconnect to the XFINITY hotspot and I would not be able to download pics on text messages. Doesn't make sense to me, but that's what happens. And even though I went into setting and disabled autoconnect on the XFINITY hotspot it would connect. So by disabling the hotpots on my xfinity gatway I solved my problem.
