Samsung Smart TV (UN46ES6100) can't connect to wireless network anymore

[cejay25]

I've had this TV for 2 years connected to my home network (Cisco router) using WEP security protocol. This week I have upgraded to WPA2 Personnal (AES) protocol. All of my home hardware (PC's, iPad,s, iPhones...) have switched over without any problem but the TV just won't connect. After entering the password, I get a connection failed message. I have tried disabling the security on the router, reverted back to WEP also to no avail. Nothing works anymore. Help please?

How is it possible for this solution to work? I mean, the problem is the TV doesn't recognize any wireless networks to connect to so how is it going to suddenly connect to the network server?

I'm having this same problem. It won't recognize any network at all. It won't update without any connection.

I fixed my problem by Reseting router to factory settings and resetting the tv to factory settings - took ages but i am now connected thanks to this forum. Thankyou

Hey folks. I FIXED MY ISSUE.

I tried resetting the router....NADA
The MAC address of the TV was already in the web interface for my router.
Tried setting DNS to 75.75.75.75 and 75.75.76.76.......NADA
Even tried setting DNS to 8.8.8.8..........NADA.
Resetting the TV itself......NADA

So I gave it a day to think about it and here is what I did.

Menu on the remote > Support > Software Update........it connected to the "network server" and my TV connected to the server and installed an update. It was WAY outdated via the version of software.
After the update installed and my TV rebooted I went back into Network Settings it connected to the internet!!!

All apps updated. Keyword.....UPDATE YOUR SOFTWARE ON YOUR TV.

Just HOW would you suggest someone connect to the network server if the problem is not being able to connect to the internet in the first place? You obviously had a connection to the internet, or else your TV would not have been able to download the new Firmware from the Samsung website, which is where the > Support > Software Update gets the update.

I'm glad your problem was solved by updating your TV's software, which is what should be done at least once very 6 months at the minimum, for any piece of electronics that has a microprocessor in it with upgradeable firmware.

I'm having the same problems as cejay25. I've tried all of the things you suggested and nothing works. Any other suggestions are very appreciated.

I'm having the same issue as well. Worked fine for over 2 years. Now it connects to the router but not to the Internet.

11-30-2016 We have a Samsung smart tv, only one year old. It stopped connecting to internet via our wifi....
we just called Costco concierge service... we had a warranty...
they, over the phone instructed us to disconnect from the back of the power cord, cable and everything plugged into the tv....
then push down and hold the power button on the tv (not on remote, our power button was on back of tv).
Hold power button down for one entire minute.
Release button and then plug everything back into back of tv....
Yey! We turned tv on and internet was immediately restored... we fretted for two days trying to get our tv to connect back to the internet. Everything else in the house worked thru our wifi. Simple fix!

We had same problem... after one year our Samsung smart tv all of a sudden wouldn't go online thru our wifi. We called warranty for help and they walked us thru the solution... unplug everything from back of tv, then hold down for one whole minute the on/off switch found on tv ( ours was actually on the back of the tv) then plug everything back in... cable, electric, and all else... turn on tv with remote and Yey! It works again!

I had the same problem at my samsung tv ue60j6200.
The solution was to enter in the 'secret menu' with the next buttons combination from remote control: info, menu, mute and turn of button (use this combination with the tv closed).
From the menu I selected <<factory reset>> option and pressed enter button from remote control.
When I opened the tv were displayed all the wifi connections.
Good luck every one!!!!

Appreciate your prompt respond. Not that it won't connect. erratically it will disconnect and when TV is reset. All will be good till the next time this happens, like 5 times in 4 months and its becoming a pain. My other Samsung Curve 55" TV in the hall and all other devices have no issue and the Service personnel came twice but no avail. Probably there will be better answers here. Thanks .

Here's a series of things to try first:

Factory reset the modem and router.
Factory reset the television.

If these don't work, you may want to disable any firewall you have enabled on the router and also check for firmware updates for the router.

Hope this helps!
