Recent ping increase and packetloss over the past month

Hey I've been using Xfinity for a long time and used to get 20 ping on most games and servers now it jumped up to around 40-50 with 1-5% constant packet loss making it unplayable this has been happening from the past month or few. This happens on all devices including my pc which has ethernet my phone and my tv. Please check on my account to see if there is a problem in my location thanks.
