Yes it used to work fine and then all of a sudden it is incredibly unreliable. The problem is exclusively when using on-demand and apps, live tv is fine. We also use chromecast just fine so I don't think it is a signal strength issue as that is pretty reliable. I can try and post a BQM but am currently at work so it will have to be later.
Thanks for the BQM C_fass. We may need to get more information from you so we can look into your network details in addition to the BQM you've given us. WiFi connections are not as stable as wired connection and can be affected by numerous factors such as your neighbour's WiFi network and changes within the home as examples. It's always best to connect your V6 box via wired connection but I appreciate it may not always be possible.
I'm going to send you a Private Message to look at your network and V6 box to see if anything is amiss. Please reply back to it so I look in more detail.
