Hi and welcome to Just Answer. I'm sorry to hear about your TV. I will try my best to give you a precise and accurate answer.
Whoever set up the router should have given you the code (I'm assuming that it wasn't you). Some cable/internet providers will put a small label on the router or the cable modem. Have you looked there?
We have a router from AT&T Uverse wireless with access point being 2Wire998. The IP address is 192.168.1.254. On the Modem/router box is the network key: XXXXXXXXXX and the system password: XXXXXXXXXX Tried both of those for my WEP Passphrase. Neither worked. Got message saying "not connected"
The network key is the one to use.
So there has to be some other issue here.
Is your TV seeing the correct network i.e. the correct SSID, your SSID? For example, I can see three of my neighbors' routers from my home.
We can get into the router and check that the tech wrote down the correct key.
The system password XXXXX XXXXX getting into the router. Click here and log into your router using the system password: http://192.168.1.1
Let me know if you can get in.
can't get in... the number on the tower from AT&T is 192.168.1.254. Shouldn't i use that one?
Yahoo? No, you should be at your login page for your router.
Click here: http://192.168.1.254
ok.. i'm in.. now what?
Clicked on system password XXXXX is now asking for a password. i loaded in the system password XXXXX on the router.. and now its asking me to set a new password. Don't think that is what i want.
There is an apparent # : 3800HGV-B. It is the AT&T Uverse router used for both tv, phone, and internet. the Access point is: 2WIRE998
The TV may not like WEP.
Turn off Wireless Security and see if the TV will connect.
I don't know.
I am going to opt out of this question which will allow other experts to chime in.
You need a network guy.
I went to "Change Settings" on Vizio and see a different IP address. i'm going to change it to the AT&T IP address and see what happens.
my initial problem was never solved. Should still be covered i would think
