My Roku will no longer connect to my wireless. I tried the suggestions given to me before (see CaseID #127663), such turning the player off for 30 seconds and so on. My last attempt was to factory reset and to reset it. Now, when it scans for networks, the screen is blank. (Clicking the middle button at this point hangs the player. The only option is Up which brings to the previous screen.) I think my hardware is finally failing. What the policy for getting a replacement unit? Thanks.
