wireless problem with Samsung Smart TV

I have a Samsung UN46ES6150F smart LCD TV that won't work wireless to Netflix. It works if I hook it up with an Ethernet cable. The wireless adapter is built into the TV. If I take the TV apart is the adapter easy to remove and replace? How do you do that?

I happen to have a Samsung external wireless stick that I can attach to the USB port but the TV does not see it.

All the wireless network settings are correct so I feel sure the adapter or main board is bad. That's why I need to know if the internal adapter is desperate from the main board.

Help please?

 

I've been trying to find a service manual or schematic for your TV but I can only locate paid services. I would doubt that the wireless section is a separately replaceable module but without any service info it's only a guess.

You said all the wireless settings were ok. When you try to connect wirelessly is there any information appearing in the fields. There are pinging routines you can use to locate what is missing. The following is the diagnostic routine for your set.

Wireless

 

The TV puts a red X between the TV and the Router showing a failure there. It also gives a messege that it failed to connect. I had a TV repair shop that thought that the wireless was seperate from the main board.
