Samsung TVs suddenly have lost WiFi connections & won't reconnect!

[mikey59]

I can write the same detailed content that I have posted to a Samsung forum, if needed, but basically my 2 not so smart Samsung TVs have lost their WiFi connections & cannot reconnect! I have several other devices, iPhone, Galaxy phone, iPad, Windows laptop, Mac book Pro, Brother printer & a range extender in my garage, that are connected just fine.
Any suggestions?

Thanks!

Do you have the MK70 series mesh system? 

Has a power off for 1 minute then back ON with the ISP modem and router, and satellites been performed since last update?
Be sure to restart your network in this sequence:
Turn off and unplug modem.
Turn off router and computers.
Plug in and turn on modem. Wait 2 minutes for it to connect.
Turn on the router and wait 2 minutes for it to connect.
Turn on computers and rest of network.

What channels are being used on the router unit? 

If all other devices are connecting fine, then sounds like a issue with the TVs. Ask about FW updates for the TVs.

I have the MR70 router & an MS70 satellite.

I have rebooted everything, in order, when I first noticed the problem & the Samsung TV Plus wouldn't work, as the TVs aren't connected to WiFI, I do have Apple TV boxes right under each of the TVs & they have no problems connecting.

Everything else in the house is working with no issues. I was starting to wonder if there was any issues with 2.4 GHz vs 5 GHz, that I might need to set up a separate 2.4 or 5 GHz network & force the TVs to connect to that.

Try that.

This suggests that faffing around with your network isn't just pointless, but could be dangerous. You could break an otherwise fine network.

Setting up "smart" TVs, especially Samsung TVs, seems to be a painful process. Go back to the TV. Go through it network setup process.

The TV doesn't care about 2.4GHz or 5GHz. If it can't see 5GHz – most TVs don't need it or support it – the setup process won't see it.

Look for the network that the TV does find and connect to that.

If possible, and if the TV supports it, use a wired (LAN) connection. You could even consider using Powerline Ethernet to create a fake wired network that uses your mains network to connect the TV. No need to mess around with SSIDs and wifi passwords.

Aside from the fact that everything worked fine for the past year or so, I find a couple of things rather puzzling.

That the BR TV will actually see my wireless network during the process of trying to connect to it & my satellite is in the living room, directly under that TV, but that one doesn't detect any wireless networks!
I've wanted to have both TVs, along with Apple TV boxes all hard wired, just haven't wanted to spend the money to do it.

I'm lost? BR TV? What is "that TV"? What does not detect any wireless networks?

Dumb switches cost next to nothing.  <£$€20 for five ports.

Not sure how to answer inline as you did on your last post, so here goes.

BR TV is the TV in the bedroom. When trying to reconnect the BR TV will at least see my WiFi network, but doesn't connect.

"that TV" that's not detecting any WiFi networks is the TV in the Living Room. I found this puzzling, as my satellite is sitting directly under that TV, making me think that would be getting the strongest WiFi signal of either of the TVs.

Yes, I know small 5 port switches are dirt cheap, but my internet connection comes into the house in another room & the wife would hit the ceiling if I just started running cables across the floor, throughout the house. I'd need a couple of network drops behind each of the TVs, that would cost about $150 each, going up through the walls, across the attic, etc.

UPDATE: With all that being said, I was able to download the latest firmware update for the living room TV (the one that wasn't even seeing the WiFi) & after the update, it saw my network, connected to it with no problem & is working fine.

You talked about "TVs, along with Apple TV boxes". If you can plug one device into the router or satellite, then you can have a switch there to go to other nearby devices. No need for long wires. So if the TVs and Apple TV boxes are next to each other, the switch can connect to the satellite and feed both of these. I mentioned it because these MS satellites don't have as many LAN ports as some routers.

Powerline Ethernet is another option for devices like TVs that don't need ultrafast Internet.

So the challenge now is to get the BR TV to work?

Again, start with the TV and its setup routine.

While looking for an additional satellite, to put in the bedroom & used the LAN port on it, Amazon was nice enough to recommend a 'renewed' Nighthawk Tri-band WiFi 6 Mesh System, 3.6Gbps, Router + 2 Satellites system for $129, so I bought that & since router has 4 ports & each of the satellites have 2, I can connect both Apple TV & Samsung TV to them & hope for the best!
