My Dad has a new Samsung Series 7 smart TV

He has an Unifi UAP AC-LR wireless access point

When he tries to add the WiFi access point as a network connection on the TV, it fails to connect with error "wireless network disconnected"

He is able to connect to the TPLink wireless router without a problem so am guessing it's something on the Unifi

We tried all the steps in this video, but setup not working


How can I get the TV to connect to the Unifi WiFi network?

As you can see, your AP device is simply too fancy! It has identified the Samsung TV as an enemy!

Perhaps connect that new TV to the AP (or the router) via LAN, so the TV has a chance to connect to the Internet, so it can download its own various updates. You could also update the TV firmware, if an update is available.

You could also change authentication settings on the AP, edit/assign exceptions in its connection configurations regarding the Samsung TV, as well as update the firmware on the AP.
 
TO the point above - is your Dad's wifi a combined SSID, i.e both 2.4 and 5ghz on the same SSID name? My TV had issues with this setup. I eventually just ran a cable to it and stopped messing around with the Wifi

This. I have unifi and when I combined frequencies under 1 SSID the TV got confused and wouldn't connect. Had to split it back into 2.4 & 5ghz.
 
Disable the automatic optimise network configuration on the Unifi Controller.

No you don’t need to separate it.

Just disable automatic configuration and do it yourself.

Settings > Network Settings > Optimizations

Turn off Auto-Optimise Network.

Now go back to your SSID configuration and put the following ON.

Enable Multicast Enhancement
Enable UAPSD
Combine Name/SSID

I wouldn’t recommend Optimize For High Performance unless you have a number of AP’s in perfect proximity to all 5ghz devices.

Aaah will give this a try! Thanks
 
i just created a separate guest network for the tv stuff and it does not do this anymore. /touchwood
 
Thought I'd chime in on this after finding this on Google. TLDR, Reset the TV and use the Smart Things app to connect it to your WiFi.

I had a Samsung UHD/Crystal TV that died, and I replaced it with a Samsung QLED (Q60). Strangely the new QLED TV refused to join the WiFi and kept saying the password was incorrect, or there was no internet, or the TV was unable to obtain a LAN IP address.

This is the same UniFi setup the old TV connected to fine so it seemed a bit strange.

It seems there are a few reset/fix procedures, I'll summarize below:
  • Power down the TV at the wall for 60 seconds
  • Reset network settings in the network
  • Firmware update (which ironically needs internet)
  • Full system reset (General > Reset)
  • There was also Support > Self Diagnosis > Smart Hub Reset
I also went all over the internet to find the solution in UniFi and I tried every variation of network settings including the ones listed above and on the UI community and did every variation of the resets above but wouldn't join the original WiFi name/password and kept saying the password was wrong.

To rule out the WiFi hardware I found the TV seemed to be happy to join my iPhone hotspot (for the firmware update), an Open WiFi network (UniFi) and any number of new WiFi networks with WPA-PSK (also UniFi), but not the original WiFi name/password combination that failed the first time.

I also observed every other WiFi name/password combo I had to press enter/done for the TV to join the network. The original WiFi name/password combo would always automatically try to join when I inputted the last character of the password.

In my case I observed no special network or AP configs, the TV would happily join a new WiFi name/password, but whatever failed the first time seemed to prevent the TV from joining the first WiFi/password combination.

What I ended up doing was doing the full system reset (General > Reset) and using the Smart Things app on my iPhone to run through the setup procedure. That time the TV seemed happy to join the WiFi.

Hope this helps someone.
