T_whitfield,
What kind of router do you have? I am having the exact same issue with 2 roku streaming sticks and one roku tv since the morning of 2/13. The wireless signal is excellent the download speed is 0. It isn't exactly 0 because I can watch things just lots of buffering and low quality. Every other device on my network is working flawlessly. I have a 400MB cable line, ARRIS SB6183 modem, and 2 eero pro routers. I spent 2 days doing factory resets, on calls with roku, eero, and ISP support. I have ruled out modem and ISP because the TV has a wired port and it works when wired. I also swapped back in my old netgear nighthawk router and wireless works on that so doesn't look likely to be the roku devices. Everything seems to point to the eeros but they assure me nothing has changed on their end. After two days of pulling my hair out I purchased two fire sticks and haven't had any issues. I am a somewhat technical person but will admit networking is not my strong suit. This problem befuddles me.
