|Hi Brian, please remember the www is truly ww.|
Where are you based - town/country?
I have found some of these dedicated 'apps' are deficient, as they are not fully compatible with say linking up *DIRECTLY* with one's pc via the internet.
It could be the wifi as your ISP says, and boosters are available as NT56 advises.
However, I would run some speed tests as a start, using various means:-
direct pc, wifi pc, direct tv, wifi tv, etc. to see if speed could be a factor.
Also try connecting to Netflix, using your tv, but via the internet, if you have an app for such.
Then use a different box, such as a PS3 to connect to Netflix, and just using your tv as its monitor.
Maybe one or more of the above will prove where the problem lies.
Here in the UK, virtually everyone has a wifi router, although directly connecting to it is better when possible, as it doubles the (device/router) connection spreed.
Good Luck - Keep us posted
