XFINITY Cable
April 28, 2026 Overall Xfinity provided very fast internet. The key is having a router that supports the higher speeds. The area we have struggled with the most is the price. We have gone back and forth with customer service to get lower rates given the more competitive prices being offered by new market entrants. Unfortunately Xfinity won't budge and may soon lose our service as the competitors provide faster speeds at lower cost.

April 26, 2026 I've been using Xfinity for about two years now, and overall, it's been a solid experience. I work remotely and stream a lot of content, and the 200 Mbps plan has been more than enough for my needs. Speeds are consistent, and I rarely experience outages. I especially appreciate the self-service tools in the Xfinity app—it makes managing my plan and checking for issues super easy.
