I watch local channel ABC7 here in Los Angeles (I watch it on HULU) a lot on my #RokuUltra. Never had a problem before. Today, around 4 pm, it started rebuffering a few minutes into the news. Every time I try it again, it restarts at the 4 pm time I originally turned it on. It keeps saying "we are having trouble showing this" but I can't figure out why. I have done all of the recommended steps to fix this -- restarted the Roku Ultra, checked my wireless connection (it is good and says signal is 'excellent'), restarted my modem, logged out and then back in, even removed HULU - restarted Roku Ultra - reinstalled HULU but still have the same problem. Don't know if this is happening on other channels or not as I am watching a football game thru a different app. Is the problem my Roku Ultra? Or is it my HULU? Or is it my WiFi (again Roku says signal is excellent)? Nothing seems to fix this proble
