Waste of time rejoining poor quality, netflix doesn't go blur so why can't nowtv get it right?
Out of curiosity what playback devices have you tried ?
i am guessing you have tried rebooting the power on both your playback device and your Router ?
All my playback devices play fine with NOW on both wifi or Ethernet (though i don't watch NOW Cinema using a PC or Mac).
If you are using a Smart TV or streaming box / stick if you go into the Netflix App under Help, Check My Network, what down speed is recorded from within the Netflix App ?
Some NOW customers seems to get a more stable stream using Google DNS on their playback devices if your device supports the use of adding a DNS.
