I have a MODEL : UN50RU7200FXZA 50 inch UHD SMART TV Series 7 (Manufactured June, 2019)
that has the same problem. This board is also littered with people with Series 7 TVs (and even some earlier) that have the same internet connection issue. I have a very good internet connection and wireless connections throughout my home and even a Wi-Fi extender plugged into an outlet right next to the TV. The Samsung TV initially will accept the Wi-Fi connection, but every night (or even after a few hours of having the TV power off) it will lose the connection and it will not automatically or manually reconnect, even when connected by Wi-Fi to the wireless extender in the same room!
It needs to be reset by either: Unplugging the TV and then replugging it in, or by Pressing the POWER button on the TV Remote until the SAMSUNG logo appears on the TV (about 3-5 seconds) . The wireless connections magically reappear after doing one of those two fixes, but there is obviously some sort of glitch either in the TV software (I have updated to the latest version) or a problem with the TV sets wireless internally.
A third solution, (but it is not really a "fix" as the TV should be able to stay connected wirelessly) as mentioned I have a plug-in Wi-Fi extender that has an ethernet port. If I run a CAT 7 (ethernet) cable from the ethernet port on the back of the TV to the extender, it STAYS connected even after powering down the TV and turning it on later. You could also run a cable directly from your router, but that is not convenient for everyone, and SAMSUNG, the Wireless connection should stay connected!
Samsung needs to address and FIX this issue with their TVs!

Tried disabling the Samsung TV channels app but had no effect on wi-fi disconnect. One shortcut I have discovered is instead of unplugging the TV each morning when it won't connect to Wi-Fi, If you push the power button on the remote and hold it down until the Samsung logo appears on the screen, it has the same effect as unplugging and Wi-Fi reconnects! Amazing Samsung has not acknowledged the issue nor provided a solution for it!

Same exact Wi-Fi disconnecting issue:
MODEL : UN50RU7200FXZA 50 inch UHD SMART TV Series 7 (Manufactured June, 2019)
Purchased last week, apparently a SKU available exclusively at Walmart.
The TV will lose the Wi-Fi connection each night and basically renders Smart Hub and it's apps useless.
It did return Error Code 107, but I still have not found a meaning for that code.
I have to unplug the TV, wait 5 minutes, and then plug it in again before my Network shows up and reconnects. I have also tried manually entering the IP address and Subnet mask etc. but that does not yield a positive result. The only thing that works is unplugging and plugging back in, hardly convenient. It will keep that connection for several hours if I am watching TV throughout the day, but if I shut it for more than a few hours, I have to unplug it again.
I have high-end fast internet router with 2G and 5G bands and also have aWi-Fi extender in the same room as the TV that gives me even greater coverage. I have even tried resetting my router and broadband modem but that didn't work either.
I checked for UPDATES from the TV settings but there were none.
(I previously owned a Series 6 Samsung Smart TV that had NO connection problems, but after 6 years suffered from another of Samsung's unsolved mysteries...the lower right side of the screen started getting hot, the screen grayed-out and the set actually started melting!!!)
I have searched the web and Samsung Community for answers and tried some of the so-called solutions to no avail. There seems to be an abundance of people with different sets through the years with the same issue. At this point, I may buy another Wi-Fi extender but this time with an Ethernet port and hard wire it with cat cord to keep a wired connection. I gave Samsung another go mainly because you just can't beat their screen...but if a working solution is not provided soon, I will not trust them again.
