I've been using Comcast 16/4(down/up) for 2 years now. Recently, my speed has dropped from 12ms to 32ms(ping), which causes my charting to freeze frequently. I called up Comcast, and all they can find is that I have strong signals, and my download/upload is good. and they'll charge me for a technician to come over and check it out. In a nutshell, comcast reps are incompetent when it comes to fixing my problem. So I spoke with my next door neighbor few days ago. He checks his speed, and gets 5ms delay(fios). down/upload speeds are similar, which doesn't seem to matter much as long as it's not too low. so I'm considering switching to fios asap. My question is: have any of you had the experience of upgrading your fios service from 15/5 to 25/15 or 50/20(or even beyond)? was there a significant improvement in speed(ping)? I appreciate your thoughtful feedbacks.
