The UE32J4570 supports Wi-Fi. Most of the other small display diagonal televisions that are a comparable age to this television do not support Wi-Fi.
We compared this TV to all the other TVs which support Wi-Fi and we think the 32LH604 (£258.89), and the 32LH590 (£269.98) both from LG and both of which are cheaper are also worth considering.
Other TVs which also support Wi-Fi that you might want to look at include the LG 32LF580 (£261.99).
