We recently left WOW and went back to Xfinity. At least in Arlington Heights we had been experiencing connectivity issues, needing to reset the modem almost daily, and lagging. This was 60MBPS and using it for school online or streaming netflix while maybe on FB on a phone. Xfinity has us at 200 MBPS for like $5 more and we have their free dvr/stream box which is pretty nice.
