I have had my roku premiere for a year now. It's worked fine up until tonight. My kids tried to watch a show and halfway through the roku lost the network connection. We tried reconnecting, unplugging, testin , soft reset, and even a factory reset to no avail. The internet is working fine, the router is working, the roku seems to be working except for the fact that it just can't find any network connection. Is it dead? Should we replace it? Is there some magical thing I have not tried yet?thank you.
