A couple of hours ago, my Roku Express disconnected suddenly from the internet. When I tried to get back into streaming on it, I found that the device would gain connection for a minute, lose it for maybe another minute, then gain it again in what is apparently a cycle. All other wi-fi devices are working as normal including another, newer, Roku Express and I have restarted the Roku Express several times with no avail. I've had the device in question for almost four years .
