There's a slim chance you may have interference from your neighbors. My suggestion is change channels on your router like I did --
You see that 3rd picture with the Channel 7 setting?
My router was ROLLING the channels, and I selected/LOCKED the channel to channel 7. Less neighbors, more signal strength.
But...when you have a weak signal, the TV usually states it cannot CONNECT.
We are constantly getting dropped signals when watching Netflix between the hours of 6-9pm
If you're watching Netflix and you DROP the movie....that's usually the VIDEO QUALITY is too high or too many people online with Netflix.
If you attempt to access Netflix, and you cannot CONNECT to Netflix or any other service like BBC or MSNBC, then that's more related to the possibility that you DO NEED to switch to a Locked /Nonvarying Channel on your router.
Rolling frequencies can cause issues, because when you get near the higher frequencies, the Signal distance shrinks.
The laptop works....you could be closer to your router, or the antenna or channel on it might be better.
The only other possibility is that your TV's connection (via software) is just plain bad.
Did I show you how to Disconnect/Reconnect your TV to Netflix?
No I didn't --
That reconnects your TV to your Netflix account with a brand new connection. I've seen that fix issues like yours.
You have a lot of possibilities that can mess with your TV set.
So....Set your Netflix account to Medium
Set your router channel to a low number like channel 7 or lower.
Deactivate/Reactivate a new connection on Netflix to get rid of any software glitches.
