My Legacy Tablo buffers and is slow to access live or recorded programs when attempting to play. This started happening a few weeks ago and has gradually worsened to where it now starts to play (after an extended loading time) then buffers and drops the WiFi connection after a few seconds. The Tablo seems to be working fine otherwise (records, fully functional with the App, etc.), the problem is only when trying to play a program. It is updated to 2.2.60 and is recognized by both the Legacy and Gen4 Apps. WiFi strength is not the problem as all other WiFI functions to the ROKU and computer etc., have no issue. Is the Legacy Tablo Device defective or could it be due to a recent ROKU or Tablo software update?
