i am having the same type of problem and since it only started around the first of the year i suspect we have a roku software issue. usually i could get it working by unplugging my TV and waiting a minute or so but today that wont work. It tells me I have poor download speed but a speed check shows i have like 400mbps download speed. i contacted the TV maker sanyo and after doing a factory reset they said its a Roku issue. How do we get Roku to address this problem?
