Samsung Q70 TV Not Connecting to 5ghz Internet

Hello all! Hopefully you can help me, I'm at my wits end.

 

My Samsung TV was working great up until a few days ago when the internet stopped working on the 5GHz connection stopped working. The 2.4g works just fine, but the 5GHz has major trouble. It will always connect to the router, but never has an internet connection over wifi. I have not tried wired yet, as that would require an extremely long cable. 

Steps taken based on suggestions from the website:

1. Try DNS server 8.8.8.8 or 2.2.2.2. Neither works for me.

2. Try rebooting the TV. Works for about two minutes, and then stops working. 

3. Resetting the router. Has the same effect as above.

4. Even tried resetting my wifi password to see if it was a traffic issue. The issue even remained, is it was the only device connected.

5. Checked for software update. No luck.

 

I'm buying an Ethernet cable as we speak to see if it potentially fixes the issue. 

 

Has anyone had any success in fixing this error?

Hi @Pixelcole obviously connecting via Ethernet may well provide a more stable connection, however the wifi connection has usually been fine for me and can be more convenient.

The Google DNS Servers are  8.8.8.8 and  8.8.4.4. Others alternatives such as OpenDNS here https://www.expertreviews.co.uk/technology/1404176/best-dns-servers-in-the-uk     You could see if changing the wifi channel makes a difference in the Router Admin or could split the frequencies if not done this previously.  A few instructions  from Bt and Sky for instance https://www.bt.com/help/broadband/fix-a-problem/broadband-and-wi-fi/i-want-to-improve-my-wi-fi/how-d...       https://helpforum.sky.com/t5/Broadband-Talk/How-to-separate-WiFi-bands/ba-p/3530610  

on another point when you say  you rebooted Tv and router did you actually disconnect from mains  as sometimes that can  be more effective.
