Let me explain my home set up first

I have a 300 mbs fibre plan and the router is in the garage because that is where the patch panel is.
Everything that is connected via ethernet, works fine.
Wifi becomes marginal at the farthest point from the router.
I have multiple ethernet ports around the house, which includes one port in the study (farthest point) and one port in the bedroom (next to the study).

In the bedroom I have a new Panasonic TV (TH-43LX800Z) and when connected by ethernet, I have no problems.
However the bedroom ethernet port has now been used as an HDMI Extender (and that works perfectly), which means that I have to use WiFi for the bedroom TV.

I installed an Edimax AC1200 Dual-Band Wi-Fi Access Point in the study which is wired directly to the router using the study ethernet port.
I connected the study computer to the AP by an ethernet cable and, using the Ookla speed test, I get 283 Mbps download and 97 Mbps upload.

The AP is set to broadcast on the 2.4 Ghz and 5 Ghz channels and using a Samsung S9 phone in the study, I get 265 Mbps on the 5 Ghz band. I get 232 Mbps in the bedroom standing next to the TV.

I have set the TV to connect to the 5 GHz band and this is when I have problems.
If I am watching live TV, a message continually flashes to say that the WiFi is not connected.
If I try to watch an App (say TVNZ+) I have trouble connecting and if it does start playing, I get the attached message:

Note that although the picture has been replaced by this screen, the sound track keeps playing.
When I click on "try again" the picture comes back, but goes again shortly after.

I have tried the 2.4 Ghz band, as well as the Router Wifi, with the same result.
I have also tried watching on an iPad and it works fine.

Any ideas? Please don't suggest running extra ethernet cables, as that is not an option.

Thanks

Couple of things spring to mind...

Do you have a Chromecast (or similar) you could test in the TV instead of its WiFi? This would help eliminate/identify it as the TV WiFi being the issue
Is it possible the TV is jumping access points and using your Router some times? If you've used the same SSID this may be happening. Try changing the name on the AP and using that instead. Also ensure you "forget" the old router SSID

Check your router/ap settings and see if it has an option 'fast roaming' if so try disabling that. Some devices occasionally have issues with AP's trying to get them to switch channels or APs. You could try turning down the signal strength of either the original wifi router or the AP to insure that TV can only see the wifi signal from one of the two sources, that will stop the TV switching between the sources and getting confused. If they're both using the same SSID then it's possible the TV is incorrectly connecting to the more distant router at times.

Thanks for your responses

The AP has a name similar to 'MainNetwork 5G' (and 2.4G) and when I installed the AP I renamed the router 'MainNetwork - Guest 5G' to try and avoid any possible conflict.
Is that what you were meaning?

I'll get the TV to forget the router and 'MainNetwork 2.4G' to see if that makes a difference.

I am not familiar with Chromecast, but can I Chromecast direct to the TV or does it require some form of Dongle?

Run a long cat 6 cable and mount the router in the center

Yes, thats what I meant.

Definitely try this, and the 5G one to the router if you have that configured on the TV as well. If you renamed it on the router as you say you're probably fine there.

I meant a separate dongle as that'll have its own Wifi aerial. That way you can confirm if its the TV with a problem, or just general Wifi connectivity where the TV is located.

I don't have Chromecast, but I do have an Apple TV device connected to my lounge TV. Will that do the trick?

Tried using the 2.4 GHz SSID only on the TV?

I expect the TV is having trouble with a particular WiFi setting on the Edimax extender. A couple of things to look at:

1) From the Edimax, can you see connected clients? What does it say about the TV? RSSI / MCS if available.
2) If you log on to your router, is it handing out a DHCP lease to the TV? Does it show a lease expiry time? If the TV is constanly disconnecting and reconnecting it may show up in the DHCP lease.
3) Can you temporarily move the router closer to the TV by patching to the study for example. The idea is to see if connecting to the router's wifi is more reliable.
4) Any firmware updates for the TV that need to be installed? Would need to connect via ethernet obviousaly to check.

freitasm: Tried using the 2.4 GHz SSID only on the TV?

Correction to my original answer.
Yes I had tried 2.4, but the 5G band was also logged in.

I went through each SSID and forgot them and then re-logged into the 2.4 G band of the AP.

Initial testing looks OK. Certainly logged onto the channel quicker and I got no messages when watching live TV.
No one is watching TV at the moment, so will try tonight and report back in the morning

Thanks

UPDATE

Since putting the TV on the 2.4 GHz band only, I have had no further issues.

Thanks for your collective help, particularly freitasm

I have the exact same TV on a Unifi network. TV seems to take probably 10-15 seconds to connect to Wi-Fi when I turn it on, but when it connects, it stays connected until you power down/power up the TV again.
