I have a Hisense Roku 55R8F and Century Link Fiber 1 gig internet. After about 3 months, the TV stopped connecting via wife or wired. All other devices, other TVs with Roku adapter, computers, cell phones and printer connect with no problems.
I have un plugged TV for 2 minutes. Unplugged router for 2 minutes, all to no avail. For a while I was able to put a Roku adapter to the back of the TV and pressing the pause button on the remote several times and the Roku adapter would connect. Now the TV only recognizes the Hisense Roku and of course won't connect.
I am currently using my iPhone as a hot spot and am able to connect.
What is the fix? Hisense says it is a Century Link issue. Century Link says absolutely not. Then Hisense said to call Roku who only supports new product connections.
I am about to throw the TV away unless there is a fix and obviously never, ever buy a Hisense product again. What crummy support.
