every night around 7pm, my 8meg service drops to a1meg. it'll stay that way till 1 am or so. like clockwork every night, and Comcast says my service shows no issues... side note to that my upload never dips at all, stays a steady 1.5...
My Comcast connection does the same thing.Download suck /Uploads stay good. My theory is Comcast oversold the node and between those hours everybody on their computer or their telephone using up a lot of the bandwidth.
