Nope, I have CenturyLink as my ISP, and have no issues with any of my Rokus. So it's something with the CL router that is messed up. Not saying it isn't something that CL can control, but I'd log into the router/modem and see if there's any settings that might be blocking Roku access.
I have Centurylink and have had nothing but problems. The roku just will not work with the world's worst internet service. I'm stuck because they just don't care. I have no answers so I'm stuck with two roku devices that I can't use.
