This fact really pisses me off. On one hand I didn't want smart features but I have to opt for a smart tv as invariably the higher priced ones have best PQ but come with these features. Now on the other hand if I buy such a TV it would be a waste if one doesn't use the features, as in your case...I guess I shall have to give it a try at least & see..
Btw would my reliance usb dongle work if I attach it to a smart tv?
No it would not work since your tv is not smart enough to interact with this any dongle. If it isfor internet on tv and not high speed videos on youtube then wireless can still work out with high powered routers and / or wireless bridges. But nothing beats wire though until AC protocol in dongles take over N.
