Question: only works with n router? Ok...this would be my first venture into HD tv and such.  One question - do you have to have an n router, or can you use a g router and connect via an ethernet cable?I currently have a linksys g router that has performed admirably for all these years.Thanks
Document: I bought this a year ago and was very excited to try out the internet features. Not exactly what I expected but it was ok. First of all the tv would randomly cut on and off several times a day. I called multiple times and would get different answers. Finally they said there was a needed Firmware update which took almost a year to have ready. There were other issues with the internet apps and getting it up an running. Finally had to purchase a Cisco wireless router.
Bought this 37 inch Vizio from Amazon and see the price has recently increased by $150!Set up was fairly easy, though we have not investigated all the features yet. Bought a Netgear wireless router, but used a hardwire ethernet cable to connect the TV to the internet in anticipation of streaming Netflix.
The only fault I see so far is blurred motion with the picture quality, especially when there's rapid movement with darker frames. It doesn't happen too often but it can be annoying. The speakers that came with this tv is okay. Just hook it up to your sound system for a more theatrical effect. Now, the internet applications for this tv surprised me. The setup took me about 5 minutes to connect wirelessly to my router. I stream movies through to this tv via Netflix.
So an upgrade from 60 to 120 is a great start.3. The wireless internet wi-fi connection works great. It was easy to set up. I am using an old Linksys Wireless 802.11N Router (Model WRT150N) running with encryption. It's connected to a cable modem with Time Warner Road Runner service. I just had to shorten the password to about 22 characters. If you get good wi-fi reception in the room, then the tv's internet connection will work just fine.
It would be ho-ho-riffic if I had a credit to spend on a replacement TV. (update 8/8/12) Ok there was a firmware update which made off to on time go to nearly 3 minutes, which makes it slower to turn on than my grandfather's tube tv. Bad news for me, my router died and thus I needed to re-pair my TV with a new wireless router. Shazam!
Stand is nice, sleek. Setup wizard guides you through setting up all your devices, so easy, loved that. I just connect a antenna (don't use cable) but where I live I can get 63 channels but they are in HD so I'll watch shows about K-Pop stars. You'll enjoy if you go for it. Best.
Vizio did it again with this tv. It took all of 20 min to unpack connect, install new apps, and enjoy. I have a 61 inch 1080p Samsung in my den which I thought no one could match, but I was wrong. Picture quality is amazing. Setup on this new Vizio was super easy, and it connected automatically to my router within seconds. You won't be able to find anything better for the price.
I am using this as a spare tv in the bedroom. Great picture and sound. The remote is ok. It tends to "wobble" a little bit when you first pick it up, since it is one of those slide out keyboard types, but it is not a problem.
(seems they have a one man operation) I asked for someone to come onsite (because that's what they do for repairs) and the rep launched at me and said that wasn't going to happen. So far I have owned this model for 7 weeks and only been able to use it for just shy of 5 weeks. When it works though everything about it is nice. Sound is ok but I have it plugged into a sound system.
I've run my desk computer's internet connection via wi-fi so I knew I already had a good wi-fi connection. You can also connect the TV directly to the internet via an ethernet cord.4. The sound is very good for my purposes. What do you expect? It's not close to what a Bose 5+1 sound system will get you (which by the way is really nice), but for a TV speaker it's still very good.5.
Answer: I have same router and  it connects to TV wireless without any problem. Wireless n bands are compatible with older routers.
