Is your cable box plugged in with hdmi?
Were there any changes to your home network, modem, or router along with the new box?

Customer: replied 8 months ago.
plugged in with hdmi. had a new cable box put in and this is when the problem happened with the wifi connection to the tv. all other devices work with wifi
Customer: replied 8 months ago.
when i reset the tv settings the message says that all settings will be reset to factory settings except network settings. That is where the problem lies

My apologies for the delay. The site is not quite instant, but please try to send only a single response and allow me time to receive it and respond back; multiple messages can get lost in the queue and further delayed.

Expert:  Nathan replied 8 months ago.

Initially, if you go into the samsung menu, under network/wireless, does it "see" any wifi networks at all?

Customer: replied 8 months ago.
Expert:  Nathan replied 8 months ago.

Thanks for confirming, that indicates a hardware problem, meaning that the tvs internal wifi adapter has actually failed.
This is a pretty common problem, they often fail all on their own just from overheating as they are very small and underpowered for the work they are expected to do within the shielded frame of the tv. In your case, it was most likely damaged from a static shock or power surge when disconnecting/connecting the cable box.

This is something that could be fixed, but isn't worth the cost to repair (or even the time to file a warranty claim), as there are quick and inexpensive alternatives. If close enough to the router you can just plug it in with an ethernet cable. If not close enough you can approximate that same connection via a

powerline ethernet adapter: or wifi bridge: either of which will link up with your home internet connection and relay that to the tv via the ethernet port.

My apologies for the news.

If you have any other questions, just let me know. Otherwise, please take a moment to rate my service as this is the only way I am credited for my time.

I connected the ethernet & now have a connection from the cable box to the tv but still no internet connection. Thoughts?
Expert:  Nathan replied 8 months ago.

Well that is not the same thing.

You need ethernet from the tv's lan port to the ROUTER, not to the cable box.

Customer: replied 8 months ago.
I stand corrected. It is to the wifi box not cable box
Expert:  Nathan replied 8 months ago.

So you have an ethernet cable (looks like a phone cord, but the plug is about twice the size) from the back of the tv to the router?

Customer: replied 8 months ago.
Tv shows connection between tv & router but not router & wifi.
Expert:  Nathan replied 8 months ago.

It doesn't need wifi, if physically plugged in with a cord, that is all that matters. Go into the network settings, and it should show the status under Wired.

Does it show network connection? Internet connection?
