Is your router obtaining an IP ?
Its possible for wireless routers to be online, broadcast an SSID, and allow devices to connect to it without having a connection to the outside world.
Yes..In my case it was the Firewall that would not let my Vizio reach the Internet...However the Vizio was communicating with my Belkin Router.
In other words it is because of this communication / Handshake between Vizio and Router that the router checks the Vizio information for validity and then if all checks out ok, then and only then will the router let it pass on to the internet and make a WWW Connection.
In the network section on the TV, go down to test connection. What speed #'s are you getting back?
I did not see actual #'s but at the end of the initial Connection Check, it stated that the connection was there but that it was so slow that most streaming and usefullnes did not exist.
This was again because the Firewall was shutting down access to the internet.
Once I corrected this, it is now Flying on the Net..Very Fast.
Got any other devices in your home successfully connected (wireless) to this router and getting an outbound connection?
Yes, I have three and now with the Vizio I have four devices, an HP Pavilion Elite, HPE112y HTPC with WiFi, an IBM Thinkpad Laptop and a Sirius Stilletto 2 radio.
I, for Security purposes enabled "MAC Address Filtering" awhile ago...With MAC Address Filtering the router allows only those specific MAC Addresses to securely connect to my Network and Internet!
I live in an Apartment Complex so it is a Secure way of shutting out all other MAC Addresses in my Bldg.
However for some reason it did not like the Vizio MAC Address, (Located in Networking under "Manual Settings") so once I Disable MAC Address Filtering the Vizio came Alive!
Not quite sure why, but I do have my Belkin Routers other Wireless Security options enabled, including Password Protected and locked down.
The MAC Address Filtering was probably overkill as it was, so no big deal.
That's about it.
Bottom line is that all of the Internet Apps are now very functional via WiFi.
PS. There are at least 6 wireless Networks in my Bldg, but myself and one other, are the only two that are secure!
I know people that live in Apt. Bldg's and never pay for Internet access, they just piggy back onto one of the many un-secure Networks available, Wild!
People have "Home Networks" and just don't know or know how to at least Password protect their network, I know that my Dad would not have a Clue..if your here your probably Tech Savvy enough that your Network is Secure, but if this is your first foray into WiFi,
I can hear some people saying, Shhh, don't say anything about that! LOL!
