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?

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!

Changing from WEP to WPA might have changed the router to no long syncs with wireless "G" by default. Since WEP limits wireless N to 54 mbit data rate (same as wireless G) it might work. You might want to check if there is a b/g/n compatability flag that needs to be set in the router wireless settings. It might be set to "n only" ...

Had the same issue. This is not the router as I tried 3 different. An update of the firmware to VERSION : T-MST10PDEUC-2004.1 solved my problem instantly.

You can download it from http://www.samsung.com/dk/support/model/UE46ES6565UXXE

Just unzip it to a USB stick> put it in your TV-set and go to support > softwareupdate and update from USB.

Hope it helps.....

You might need to update your software. Call 1-800-SAMSUNG (726-7864) and they will email you the most current software with instructions on how to install (you will need a flash dive). Good Luck!

I'm in the same boat. I've spend hours on the phone with Samsung. Reflashed the TV's firmware from a USB. Placed router in same room with TV. Reset TV to factory defaults. Reset Router. Checked router settings. Nothing has worked. Finally the Samsung represenative suggested I buy a new TV, as my two year old TV was out of warranty, and there was nothing else they could do to help me. Really?

is is it safe to disable the firewall on the router? I am having the same issue only I was using an old router and it worked fine. Then I bought this new AC1900 router and I could not get on the internet. It appears it cleared to the router but the router would not let the signal out to the internet.

Not sure if this will help. I had a similar problem with my Samsung UE40ES6300UXXU SMART 3D TV. I have had it for a couple of years and decided I would like a sound bar to complement it so I bought a Samsung HW H450. In the process of installing it I found that my TV was no longer connected to my Network. To cut a long story short after several days of trying different things most of which has been mentioned by previous posters I made a wired connection to my network. When the wired connection was up and running I was then able to wirelessly connect with none of the problems I had been suffering previously.

I finally disconnect the firewall on the router.. Got online. Then I added one component to the firewall at a time and verified I could get online each time. Doing this I found out what was causing the problem and unchecked it so it would not be used..So far its working. Thanks for all the help..

I had the same problem plus it was turning on and off. Called Lifetime Services centers and they came out and changed the Wifi card which was the problem. Had to call Samsung center and had them update the system and now everything works fine. Took a while on the phone but was worth it. Now things are working fine. Cost was $210. Hope this helps you out.

Go to Menu, then Support, then go to Software Update. I used the Download option NOT USB. I waited a few minutes as the Download processed. Once done the TV shut down & then turned on by itself (as mentioned on the screen). Once the TV a turned back on, I was able to go on the Internet.

Unfortunately it may be a hardware problem. The wifi card has failed in my UE46ES7000 twice now, first time just outside the Samsung warranty. I do have an extended warranty though. This time, a year later, even the wired connection won't connect to the Internet, but it sees the router just fine. The TV is not even three years old!

I was having a similar problem, it would connect to router but not Internet. My wifi was working and Netflix on another tv was. I downloaded the software update even tho I didn't think it would work since I couldn't connect to Internet. To my surprise it did and then it prompted me for a Netflix update and now Im up and running :) . Thanks

I used a WiFi extender to solve the problem with my Samsung 46" Smart TV, UN46ES6100.

Only two years old, the TV initially had spotty connectivity, then finally failed to connect to the internet entirely. I could see the wireless network I wanted to connect to in the Network setup process, but after trying to connect, it would fail.

After 5+ hours on the phone with Samsung support over the span of about 4 phone calls, the determination was made by Samsung that my WiFi card in the TV would need to be replaced. That option didn't appeal to me, so I headed to Best Buy to purchase a Roku box and offload "Smart" from my TV. Fortunately, the Best Buy sales guy pointed me to a WiFi extender to solve the problem instead. It attaches to the back of the TV, plugs into the ethernet port (which still works) to deliver the connectivity, and draws power from the USB port on the TV, so wireless has been restored for $30. Brilliant!

The key to this solution is that you have an ethernet port on the TV, and it is still working properly.

I used the Netgear WNCE2001, but any equivalent device should work.

It's apparently a Samsung problem, currently affecting most of Europe on D and E series TVs. Called them yesterday, they said they're "aware of a problem" and "engineers are working on it". Not very fast, it would seem. Whatever the problem is, it's crapped up their DNS system - all the Samsung smart TVs need to connect to their servers before loading most of the apps, for some reason. So, don't keep resetting routers and pulling cables out, it won't fix things. It's been over 24 hours, so - hopefully - they'll have a fix soon...

HTH.

I had to do your procedure twice. 1st time TV power went off. 2nd time a window popped up showing download progress. Stand by. It only takes a minute. I reconnected to internet thirty seconds later.

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!!!

I had the same problem. Got the firmware update from Samsung, used a usb to update. Then it took a few starts and stops for it all to get in sync. One app needed to update, then another, then Netflix. What pisses me off is who in their right mind would design a tv that would suddenly stop connecting to the internet because firmware is not up-to-date. They should take their smart tv concept and stuff it.

I'm having the same issues here. Bought our Smart TV in 2012, in 2013 we used Netflix with no problem, WiFi was working fine.

6 months later, it stopped detecting Wi-Fi signal. We tried a WiFi signal expander, (didn't detect it still, even after connecting the expander to the TV through Ethernet Port), yes the signal on the house was improved, but the TV still didn't detect it. It was kind of a cheap expander (around $30), so I don't know if a better one would fix the problem (I saw someone suggest a NetGear which costs around $60-$80). I'd be happy to try but I'm not sure this would do it, because I connected our Blu-Ray to the expander and it did work, so it should work on the TV too right? (Although the TV is farther from the router). I'm just hesitant about spending on another expander just to find out it wouldn't solve the problem.

After hours on phone with Samsung Tech Support, they told me that my Wireless Card was probably broken, due to power variations, and they suggested taking the TV to a repair center. Since my TV is 3 years old, I'm assuming this is not gonna be covered by warranty, so at least I'm calculating $200 to fix it. Waaay too much honestly. Any of you guys think connecting a WiFi wireless adapter to the TV (through USB) would work? I'm not sure it would override the internal LAN adapter TV has. :(  (P.S. We did all the updates etc, etc,)

I tried almost all the suggestions that I've seen on these forums to fix this same problem with my Samsung UN40ES6100F, including searching for s/ware updates. I finally contacted Samsung support via chat, who advised me to switch the DNS address to 8.8.8.8. This worked for me--it would be nice to know what the variables are that cause some suggestions to work for some and not others. But for now, I'm just glad to get internet back.

I just thought I would post this solution here after I spent several days and hours on the phone trying to get my Samsung Smart TV to connect to the internet. After having the television for 2 years with not problems at all, suddenly it would not connect to WiFi. The last tech at Samsung that I spoke with knew exactly what to do and my TV was back working and connection to the internet within a few minutes. He told me to reset the DNS to 8888.
Detailed instructions for the computer challenged community such as me:
On your TV remote, go to Menu, Settings, Network
Next select Network Settings, Start, IP Settings
Then select DNS mode and make sure the green check is on "manual"
Enter 8 8 8 8 and OK
Bingo, instant internet
(note - I also was told to click on Samsung Smart Hub in upper right corner. I had reset my TV and it needed to update and add back my programs)
I have a Samsung Smart TV Model No. UN553S6500 (a 2012 model)

I have the same issue with my Samsung smart tv. Its been updated and I've tried every troubleshooting tip I could find but the problem is with the tv. Samsung told me to either buy a new one or pay for servicing. I paid too much money for that tv to have to pay anything at all this soon. I have ancient tv's I'm still using with no problems. For that kind of money one should expect the equipment to last longer than a few years. I'm just not doing it and I'm also never buying another Samsung. If you search around you'll find lots of folks with this issue. Just my opinion but Samsung ought to take care of their customers on this since there's clearly some kind of issue with their tv's.

I tried everything you tried first and after making several calls to Samsung, I called again and spoke to another tech who immediately told me to reset the DNS to 8888. That solved my problem immediately! The code may be different for where you live. I don't know that just that is my line of thinking since I am no computer wiz. You might check with Samsung help number again and suggest that.
Here are my simplified instructions:
On your TV remote, go to Menu, Settings, Network
Next select Network Settings, Start, IP Settings
Then select DNS mode and make sure the green check is on "manual"
Enter 8 8 8 8 and OK
Bingo, instant internet
I hope this helps. I am sharing because I had a very frustrating experience too. My TV is now two years old and this is the only issue I have had with it. All the techs I spoke too were extremely nice except two who both tried to get me off the phone as soon as possible, but then you can get that anywhere. Good luck!

I have 65" Plasma 2011 Model#PN64D8000FFXZA. My internet works fine and my router shows that it is connected wirelessly to the TV.
Problem:
TV was not able to launch Smart Hub Apps (Netflix, HBOGO, etc.) after recent automatic software updates. Shows error message that wireless network interference occurred try again later.
Observations:
Not able to launch apps from TV (netflix, etc).
Able to download new apps to TV.
TV Network Settings showed that it was connected to network but not to internet.
Able to browse internet on TV using its Web Browser (this was a huge giveaway that the way Smart Hub launches its Apps are the problem).
Solution:
I went online to samsung.com and downloaded the latest software to a USB drive and updated my TV manually since the TV kept on telling me that there was no new upgrades available, this did not solve the problem, but you should update your stuff when troubleshooting. What solved the problem for me was that I changed my TV DNS Server settings to 8.8.8.8. Perhaps Samsung has screwed something up in their latest Smart Hub update and/or something is wrong with their DNS servers as mentioned by a previous poster?

I had the same issues with my ES model. when trying to get on wireless for smart hub, menu would disappear and i couldn't get on. Wired worked for a day and then stopped. I called samsung, they tried everything and it didnt work. They said they would escalate the issue and call me back, but never did. Second time they said they would call but didnt. I updated the software to 2004 now and wired started working, but wireless doesn't work. Thank god i have a warranty with PC richards. I called them, a tech came the next day and knew the issue. He said the ES models are not compatible with the new 4gig routers. The antennas the samsung TVs come with are faulty. He replaced that piece and now it works. Samsung Customer service is the worst. PC Richards tech knew the issue right away and has had to deal with this for a year now. If I didnt still have a warranty, i would have to pay $350 for this part. Jeez. Hate Samsung.
