I checked for software my TV is is from 2010 and Samsung doesn't have any new firmware updates anymore. so I guess i am stuck with this - although I will try another HDMI jack not sure what will that change
I think my Samsung TV is also a 2010 model.
Unless things have changed, only one of the HDMI ports on 2010 Samsungs is the Anynet port. So switching your

TV to a different port should break that functionality in your case.
OR, if your Samsung has Anynet on all ports, maybe the port to which your

TV is connected is funky and it will work fine in a different port.
One more idea: swap HDMI cables just to rule out some kind of cable issue.
I'm sure lots of us have Samsung TVs and 4th gen

TVs. I can't recall ever seeing a post with your problem. So I suspect something is broken in your setup. Potential culprits: 1) TV, 2) TV HDMI Jack, 3) HDMI cable, 4)

TV. You can rule out #2 & #3 by simple swapping and retesting. If #1 has worked fine for years and/or if other Anynet hookups works just fine, I strongly suspect #4. On the other hand, if

TV is the only thing with which you've tried using Anynet, it could be #1. If you have another

TV 4th gen or could borrow one from a friend, it would be easy to pin it down to either #1 or #4.
If you happen to have a receiver in the chain from

TV to Samsung Anynet HDMI port, test a direct connection to rule out the receiver or the extra HDMI cable in that kind of hookup.
Basically, use some step-by-step tests to pin down where the problem is. I strongly suspect it's either TV or

TV based on what you've shared. But a borrowed

TV and a direct connection if applicable could pin it down to a single thing.
