Our 2 TVs lock up occasionally at separate times and the frequency has become unacceptable. The STB with the Sony will click with "18.104.22.168", dui, channel number, blank and then repeat this as if lost. None of the STB functions(buttons) will work. Sometimes this happens immediately after turning on the TV. The Visio TV's picture will freeze and the STB will halt with the channel number. Reseting the router and powering off the STB does not give immediate resolution. It usually takes around and hour to get things back to normal. Are both STBs bad or is it beyond that? This unreliability is most frustrating.
1. Check all the cables for tightness, all the way to the ONT.
2. If this happens very often, try turning off the router for a while and see if the problem goes away. Of course, you won''t have internet, an updated program guide, or VOD while it's off.
3. Call for a service tech.
