I too have been noticing terrible latency during the evening hours, with disconnects intermittent as well. This is terrible, expecially with our phone going through them. We lose our phone service 2-3 times a night right now. I've called repeatedly, and the tech comes up during the day (when the connection is fine) and says nothing is wrong, 2-3 hours later (after 5-6pm) it goes to pot again. urgh.
