[nmglug] Not a gnulinux problem but...

I apologize for this being a non gnulinux problem but I don't know what else to do. My Roku is not working. The device starts but I cannot connect to any app. Checking setting shows my network is fine but no download speed, 0. I cannot connect to any roku website on my laptop or phone. I cannot contact customer support. It's as if my modem is choking on all roku. Since I can't get any web help I thought that I'd throw this out there and hope. I really appreciate any help. Thanks Brian --
