I have seen similar postings but no solution. Issue: tv will say it's not connected to wifi and whatever app I'm running tells me the same thing and app stops working. However, all other devices are connected to wifi - phone, laptop, etc. The connection restores in a few minutes with no intervention. Here's what I've tried: unplugging the router, several system restarts, and checked for updates for the roku os. Any ideas would be welcome. Thanks
