VTV works fine on WIFI. We have ours connected by WIFI and like the OP doing wired ethernet is not an option.

 

But what other devices are on your WiFi network contending for bandwidth, this we dont know as is the case with Ray's setup. WiFi is not a very optimum transport if you are wanting low packet loss, low jitter and modest throughput (as streaming does) a slightly contended wifi network is not overly noticed in its poor performance when just browsing or email etc, but if you want to stream it needs to be pretty clean for packetloss and jitter. If you have lots of clients (even a few) on the same band/AP those requirements can quickly go out the window.

So to say WiFi works fine at mine may not cover the situation, just saying.

Ray, do you know which band the VTV is using 2.4 or 5GHz, if its 2.4 then maybe try force it to 5GHz, this is typically cleaner and has higher capacity assuming its set for 40MHz bandwidth. Also try check that other nearby APs are not sitting on the same channels as yours.

So I still come back to my orginal comment, it would be good to test live TV, in particular from Sky Sports via ethernet and compare with WiFi to see if it is infact part of the issue.
