now i understand that either sony dongle or d-link above is just a tool to enlarge the wifi signal for oher receivers, it does not have any tv relevant function at all, so why do i still need a strengther?
the tv can receive the single from wireless router... stranger.
Hi,
I'm a little confused by the question. Let me revisit the original suggestions in more detail to see if that helps:
"1, Ethernet cable from router (cheap)"
Most WIFI routers also have around 4 ethernet ports in them (i.e. for a wired connection). The TV (presuming it is the same as the 46 inch model connection wise) also has an ethernet port in the back. You run the cable from the router to the TV. No WIFI involved between router and TV.
This option is good if the router is near TV and/or there is an easy way to discretely run the ethernet cable between the two without having a big wire visible and in the way.
"2, Homeplug (get 200mpbs)"
This is also a wired connection - not WIFI. You plug a homeplug into a mains socket near the router and a second one near the TV. Each plug has an ethernet cable sticking out the back, you plug each into your router and TV respectively. This effectively simulates a long ethernet cable but as mentioned by others is not as cheap or reliable, but arguably more reliable than WIFI might be. This is what I use and it is fine for me.
"3, Buy the very expensive Sony WiFi adapter but be aware over wifi you might not have enough bandwidth to play smoothly if your router is only G and not full 300mpbs N."
This is the option to use the WIFI signal from your router instead. No wires at all between router and TV. Same price as homeplugs (ish) but arguably not as reliable. The TV in question will not pick up a WIFI signal without this extra dongle.
"4, Stick your to your HDMI connection."
If you can just put the laptop next to the TV when you want to use it, leave a HDMI cable hanging out the TV off to the side for use when needed. I still use this method occasionally for HD content etc. Once running it is fine but not as slick as streaming in terms of messing around with resolutions/audio output settings are sometimes required I find. And streaming is nicer as can all run off TV remote.
