Well, got back in here to post. It was the Linksys modem, got a TP link in mint condition, everything flies including my wireless laptop. Thanks for helping, glad it is ironed out, wish I had known that last week, wouldn't have wasted valuable time, DR
Thanks for logging back in to tell us that you resolved your speed issues and that it was not TWC-Spectrum's fault this time. Others also have reported router performance issues with Cisco's implementation of WMM on Linksys plus a general lack of adequate documentation.
